An options term describing a strike price that is equal or very close to the current market price of the underlying asset.
A volatility indicator that measures the average price range of an asset over a selected number of periods, including gaps between sessions.
A balance sheet shows a company’s assets, liabilities and shareholder equity at a specific date. Investors use it to review debt levels, liquidity, financial strength and the company’s ability to meet short-term and long-term obligations.
A basis point equals 0.01 percentage points. The term is commonly used when describing changes in interest rates, bond yields, fees and central bank policy, where small movements can have a meaningful effect.
A bear market is an extended period of falling prices, often associated with a decline of 20% or more from a recent peak. It may be accompanied by weaker sentiment, reduced risk appetite and higher volatility.
Beta measures how strongly an asset has historically moved relative to a benchmark. A beta above 1 suggests greater sensitivity to market movements, while a beta below 1 indicates lower relative volatility.
The bid is the highest price currently offered by a buyer for an asset. A market sell order will generally execute at or near the available bid price, depending on liquidity and market conditions.
The bid-ask spread is the gap between the highest buying price and the lowest selling price. It reflects trading costs and liquidity, with tighter spreads usually found in more actively traded markets.
A blue-chip stock is a share in a large, established company with a recognised brand, long operating history and substantial market value. These companies may offer greater stability, although their share prices can still fall.
A bond is a debt instrument issued by a government, company or other organisation. The issuer borrows capital from investors and may pay interest before returning the principal when the bond reaches maturity.
Book value represents a company’s assets minus its liabilities according to its financial statements. Analysts may compare book value with market value to assess how investors are pricing the business.
A breakout happens when price moves beyond an established support, resistance or chart pattern boundary. Traders often look for stronger volume or continued price movement before treating the breakout as significant.
A broker provides access to financial markets and facilitates the buying and selling of instruments. Depending on the service, a broker may also provide pricing, execution technology, research, account tools and leveraged products.
A bull market is a sustained period of rising prices supported by strong demand and positive market sentiment. It may occur across an entire market, a particular sector or an individual asset class.
A call option gives the holder the right, but not the obligation, to buy an underlying asset at a specified strike price before or on the expiry date. Buyers generally use calls when they expect the asset price to rise.
A capital gain occurs when an asset is sold for more than its purchase price. Tax treatment may depend on the asset, holding period, investor status and applicable jurisdiction.
A carry trade involves borrowing or selling a lower-yielding currency to fund exposure to a higher-yielding currency. Returns can be affected by interest-rate differences and exchange-rate movements.
Cash flow tracks money entering and leaving a company over a given period. Analysts review operating, investing and financing cash flows to understand liquidity, business quality and the source of reported earnings.
A chart pattern is a recognisable price formation used in technical analysis. Triangles, flags, double tops and head-and-shoulders patterns may suggest continuation, consolidation or reversal, but they do not predict outcomes with certainty.
The closing price is the final recorded price of an instrument at the end of a trading session. It is widely used to calculate daily returns, technical indicators and portfolio valuations.
A commodity is a tradable raw material or primary product, such as crude oil, gold, copper, wheat or coffee. Prices are influenced by supply, demand, weather, production levels, inventories and geopolitical developments.
Compound interest is calculated on the original principal and on interest accumulated during earlier periods. Its effect becomes more significant as the investment period and compounding frequency increase.
A contract for difference, or CFD, is a derivative that tracks the price movement of an underlying market without transferring ownership of the asset. CFDs can be used to take long or short positions, while leverage, financing costs and rapid price movement increase risk.
Convexity measures how the price sensitivity of a bond changes as interest rates move. It adds detail to duration analysis, particularly when rate changes are larger.
Correlation describes how closely the returns of two assets have moved in relation to one another. Positive correlation indicates similar movement, negative correlation indicates opposing movement and a reading near zero suggests little consistent relationship.
Cost of carry refers to the expenses and benefits associated with holding an asset over time. It may include financing, storage, insurance, income and convenience yield, and often affects the relationship between spot and futures prices.
Counterparty risk is the possibility that the other party to a financial agreement cannot meet its obligations. It is relevant to derivatives, lending, over-the-counter transactions and some settlement arrangements.
The coupon rate is the annual interest paid by a bond issuer as a percentage of the bond’s face value. It differs from the bond’s current yield and yield to maturity, which also reflect the market price.
Credit risk is the chance that a borrower or bond issuer will fail to make scheduled interest or principal payments. Higher credit risk generally leads investors to demand a higher potential return.
A day order remains active only for the current trading session. Any unfilled portion is usually cancelled when the market closes.
Day trading involves opening and closing positions within the same trading session. The approach focuses on short-term price movement and avoids carrying positions overnight, but requires close monitoring, disciplined execution and defined risk limits.
The debt-to-equity ratio compares a company’s total liabilities with shareholder equity. Analysts use it to assess financial leverage and how heavily a business relies on borrowed capital.
Deflation is a sustained decline in the general price level of goods and services. It can increase the real value of debt, weaken business revenue and influence interest-rate expectations.
Delta estimates how much an option’s price may change when the underlying asset moves by one unit. It is also used to assess directional exposure within an options position.
Demand reflects the quantity of an asset buyers are willing to purchase at different prices. Stronger demand can support higher prices, while weaker demand may place downward pressure on the market.
A derivative is a financial contract whose value depends on an underlying asset, rate or index. Futures, options, swaps and CFDs are common examples used for hedging, speculation and risk transfer.
A discount rate is used to convert future cash flows into a present value. Central banks may also use the term for rates applied to certain forms of institutional borrowing.
Discretionary trading relies on human judgement rather than fixed automated rules. Decisions may draw on charts, economic data, market news, positioning and the trader’s interpretation of current conditions.
Diversification spreads exposure across different assets, sectors or markets. It can reduce dependence on one position, although it cannot remove market risk or prevent losses.
A dividend is a distribution made by a company to eligible shareholders, usually from earnings or retained profits. Payments may be issued in cash, additional shares or another approved form.
Dividend yield compares a company’s annual dividend per share with its current share price. It is commonly used when assessing income-producing shares.
Downtime risk is the possibility that a platform, data feed, internet connection or trading system becomes unavailable. Technical disruption can delay orders, position changes or access to account information.
Drawdown measures the decline in an account, portfolio or strategy from a previous peak to a later low. It helps evaluate downside exposure and the depth of past losses.
Duration estimates how sensitive a bond’s price is to changes in interest rates. Bonds with higher duration generally experience larger price movements when market rates change.
Earnings guidance is a company’s estimate of future revenue, profit or other financial results. Investors compare guidance with market expectations to assess whether the outlook has strengthened or weakened.
Earnings per share, or EPS, divides a company’s profit available to ordinary shareholders by the number of shares outstanding. It is commonly used to compare profitability across companies and reporting periods.
EBITDA represents earnings before interest, tax, depreciation and amortisation. Analysts use it to compare operating performance, although it does not reflect debt costs, capital expenditure or cash flow in full.
An economic indicator is a data release that provides information about economic activity. Inflation, employment, retail sales and GDP figures can affect interest-rate expectations and market pricing.
Equity represents ownership in a company or the residual value of an asset after liabilities are deducted. In public markets, equity exposure is commonly obtained through shares or equity-based funds.
The equity risk premium is the additional return investors expect from shares compared with a lower-risk benchmark, such as government bonds. It reflects compensation for taking greater market risk.
An entry point is the price at which a position is opened. Traders often assess the entry alongside the stop level, target price and expected risk-to-reward ratio.
An exchange is an organised marketplace where approved financial instruments are traded under defined rules. Exchanges support price discovery, transaction reporting and standardised settlement procedures.
An exchange rate shows the value of one currency relative to another. Rates move in response to interest-rate expectations, economic data, capital flows and changes in market sentiment.
An exchange-traded fund, or ETF, is a pooled investment vehicle that trades on an exchange. ETFs may track an index, sector, commodity, bond market or investment strategy.
The ex-dividend date is the first trading day on which a buyer is no longer entitled to the next declared dividend. Share prices may adjust around this date to reflect the payment.
Execution is the process of completing an order in the market. The final result can be affected by available liquidity, order type, price movement and slippage.
An exit strategy defines the conditions for closing a position. It may include a profit target, stop-loss level, trailing stop, time limit or change in the original trade thesis.
Expected return is an estimate of the average outcome from an investment or strategy based on possible results and their probabilities. It is a forecast, not a guaranteed result.
Exposure measures how much a portfolio or account may be affected by movement in a particular asset, sector, currency or market. It may be calculated using capital invested, position value or leveraged notional value.
Fair value is an estimate of an asset’s current worth based on financial data, comparable instruments and prevailing market conditions. In derivatives, it may also refer to a theoretical price that reflects interest rates, dividends and time to expiry.
Fiat currency is government-issued money whose value is supported by the issuing economy and monetary system rather than a physical commodity. The Australian dollar, US dollar, euro and British pound are common examples.
Fibonacci retracement is a technical analysis tool used to mark possible support and resistance levels after a significant price move. Common reference levels include 38.2%, 50% and 61.8%.
A fill occurs when all or part of an order is executed at an available market price. Large orders or fast price movement may result in partial fills or execution across several prices.
A fill or kill order must be executed immediately and in full or cancelled entirely. It is used when receiving the complete requested position at the available price is more important than partial execution.
A financial instrument is a contract or asset that can be traded or valued, including shares, bonds, currencies, options, futures and derivatives.
Fiscal policy refers to government decisions on taxation, spending and borrowing. Changes in fiscal policy can affect economic growth, inflation expectations, interest rates and market sentiment.
A floating exchange rate is primarily determined by supply and demand in the currency market. Central banks may still intervene when exchange-rate movement becomes disorderly or conflicts with policy objectives.
The Federal Open Market Committee sets monetary policy for the US Federal Reserve. Its interest-rate decisions, statements and economic projections can influence currencies, bonds, equities and commodities worldwide.
Force majeure is a contractual provision covering extraordinary events that prevent an agreement from being performed as expected. It may affect settlement, delivery and operational obligations during major disruptions.
A forward contract is a private agreement to buy or sell an asset at a fixed price on a future date. Terms are customised between the parties, which makes counterparty risk an important consideration.
Fractional shares represent less than one full share of a company. They allow investors to allocate smaller amounts to higher-priced shares, subject to the provider’s ownership, transfer and voting arrangements.
Free float is the portion of a company’s issued shares available for public trading. It excludes holdings that are restricted or closely held by insiders, governments or strategic investors.
The front month is the nearest futures contract approaching expiry. It often carries the highest trading activity, although liquidity may begin shifting to the next contract as expiry approaches.
A funding rate is a periodic payment exchanged between long and short positions in perpetual futures markets. It helps keep the contract price aligned with the underlying spot market.
Fundamental analysis assesses an asset using economic, financial and business information. For shares, this may include earnings, cash flow, debt and industry conditions. For currencies, it may include inflation, growth and monetary policy.
A futures contract is a standardised agreement traded on an exchange to buy or sell an asset at a specified price and date. Contracts may settle in cash or through delivery, depending on the market.
Gamma measures how quickly an option’s delta changes as the underlying asset moves. Higher gamma means directional exposure can shift more rapidly, particularly for at-the-money options approaching expiry.
Gamma scalping is an options strategy that combines a long-gamma position with repeated trades in the underlying asset. The approach seeks to benefit when realised price movement exceeds implied volatility and transaction costs.
A gap occurs when an asset opens or trades at a price separated from the previous range, leaving little or no activity between the two levels. Gaps often follow earnings, economic releases or overnight news.
Gearing describes the relationship between market exposure and the capital committed to a position. Higher gearing increases the effect of both favourable and adverse price movements.
Gilts are bonds issued by the UK government. Their prices are influenced by interest-rate expectations, inflation, credit conditions and demand for government debt.
Good delivery refers to the standards an asset must meet for physical settlement. These rules may specify weight, quality, approved refiners, packaging and delivery location.
A good-til-cancelled, or GTC, order remains active until it is executed or manually cancelled. Traders should review open GTC orders regularly as prices and market conditions change.
Gross exposure is the combined value of long and short positions without offsetting one against the other. It shows the total amount of market exposure carried by a portfolio.
Gross margin is revenue minus the direct cost of producing goods or services, expressed as a percentage of revenue. It helps investors assess pricing power and operating efficiency.
Gross domestic product, or GDP, measures the value of goods and services produced within an economy over a defined period. Growth figures can influence currencies, bonds, equities and interest-rate expectations.
Greenback is a widely used market nickname for the US dollar. Movements in the dollar can affect currency pairs, commodities, global funding conditions and international trade.
The Greeks are measures used to estimate how an option’s value may respond to changes in price, time, volatility and interest rates.
Common Greeks include:
A grey market operates outside an official exchange or authorised distribution channel. Prices may offer an early indication of demand, but liquidity, transparency and settlement arrangements can be limited.
A growth stock is a share in a company expected to increase revenue or earnings faster than the broader market. These shares may trade at higher valuations and can be more sensitive to changes in expectations.
A GTC order remains active until filled or cancelled. An immediate-or-cancel, or IOC, order executes as much as possible immediately and cancels any remaining quantity.
A handle is a whole-number price level used as a reference in currencies, indices and rates. Orders often cluster around these levels, making them potential areas of support, resistance or sharper volatility.
A hard stop is a stop-loss order placed directly with a broker or exchange. It is designed to close a position when a specified level is reached, although gaps and limited liquidity may affect the execution price.
Hawkish describes central bank language or policy that places greater emphasis on controlling inflation. It may signal higher interest rates, slower rate cuts or tighter financial conditions.
A head-and-shoulders pattern is a technical formation made up of three peaks, with the middle peak higher than the other two. Traders often interpret a break below the neckline as a possible reversal signal.
Heikin Ashi is a charting method that uses averaged price data to smooth candlestick movement. It can make trends easier to identify, although signals may appear later than on standard price charts.
A hedge ratio shows the proportion of an exposure covered by an offsetting position. It helps determine how much of a portfolio, asset or currency risk is being reduced.
Hedging involves taking a position intended to offset potential losses elsewhere. Futures, options, correlated assets and currency positions are commonly used, although a hedge may introduce additional costs or risks.
Herd behaviour occurs when market participants follow the actions of others rather than relying on independent analysis. It can contribute to crowded trades, rapid rallies, sell-offs and sharp reversals.
Hidden liquidity is buying or selling interest that does not appear fully in the visible order book. Iceberg orders, dark pools and other execution methods may conceal the total quantity available.
High-frequency trading uses automated systems and low-latency infrastructure to execute a large number of orders rapidly. Strategies may focus on market making, arbitrage or small short-term pricing differences.
A histogram displays data as vertical bars. On trading platforms, it is commonly used to show momentum, volatility or the difference between indicator values, such as within the MACD.
Historical volatility measures how widely an asset’s price has moved over a past period. It is calculated from observed returns and differs from implied volatility, which reflects market expectations.
A holding period is the length of time an asset or position remains open. It may influence strategy selection, financing costs, tax treatment and exposure to overnight events.
Hot money is capital that moves quickly between markets in search of short-term returns. These flows are often influenced by interest-rate differences, policy expectations and changing risk sentiment.
A hurdle rate is the minimum return required before an investment or strategy is considered acceptable. It may be based on the cost of capital, a benchmark or a required return for the level of risk taken.
Hyperinflation is an extreme and accelerating rise in prices that rapidly reduces a currency’s purchasing power. It is often linked to severe monetary instability, fiscal stress and declining confidence in the financial system.
An iceberg order divides a large order into smaller visible portions. Only part of the total quantity appears in the order book, helping reduce market impact and conceal the full position size.
Illiquidity describes a market where buying or selling can significantly affect the price. Illiquid conditions often involve wider spreads, greater slippage and fewer available counterparties.
Implied volatility is the market’s estimate of future price movement derived from option prices. It indicates expected magnitude rather than direction and generally rises when uncertainty increases.
An option is in the money when it has intrinsic value. A call is in the money when the underlying price is above the strike, while a put is in the money when the price is below the strike.
An index tracks the performance of a selected group of securities or assets. It may represent a broad market, industry, region or investment theme and can be accessed through funds or derivatives.
Index rebalancing is the scheduled adjustment of an index’s constituents or weightings. These changes can create temporary trading activity as funds update their holdings.
Inflation is the rate at which the general price level of goods and services increases. It reduces purchasing power and can influence interest rates, bond yields, currencies and company costs.
Initial margin is the capital required to open a leveraged position. It acts as collateral against potential losses and may increase when market volatility rises.
Insider trading involves trading securities using material information that is not publicly available. Laws and permitted activities vary, but unlawful insider trading can carry serious penalties.
An institutional investor is an organisation that manages or invests large pools of capital. Examples include pension funds, insurers, banks, hedge funds and asset managers.
An interest rate differential is the gap between the interest rates of two countries or financial instruments. In currency markets, it can affect capital flows, forward pricing and carry-trade returns.
Internal rate of return, or IRR, is the discount rate that makes the net present value of an investment’s cash flows equal to zero. It is commonly used to compare projects with multiple cash flows over time.
Intermarket analysis examines relationships between asset classes such as shares, bonds, currencies and commodities. Traders use these links to interpret broader market conditions and confirm directional signals.
Intervention occurs when a central bank or public authority acts to influence a market. In currency markets, this may involve direct transactions, policy measures or public statements.
Intraday refers to price movement or trading activity that occurs within a single market session. Intraday traders usually close positions before the session ends.
Intrinsic value is the immediate value of exercising an option. For shares or other assets, the term may also refer to an estimated value based on financial fundamentals.
Inventory risk is the exposure a dealer or market maker carries while holding assets. Adverse price movement can create losses before the position is hedged or sold.
Inverse correlation describes two assets that tend to move in opposite directions. The relationship may change over time and should not be treated as permanent.
Investment grade refers to bonds or issuers that receive relatively strong credit ratings from recognised rating agencies. These instruments generally carry lower default risk than speculative-grade debt.
Japanese candlesticks display an asset’s open, high, low and close for a selected period. Traders use candle shape and position to interpret momentum, rejection and possible changes in market direction.
Jawboning occurs when policymakers try to influence markets through public statements rather than direct intervention. Comments about inflation, interest rates or currency strength can quickly alter market expectations.
The J-curve describes how a country’s trade balance may initially weaken after its currency depreciates before improving later. Import costs often rise before export demand and trade volumes adjust.
Jensen’s alpha measures an investment’s return relative to the return expected for its level of market risk. A positive result suggests historical outperformance against the selected benchmark model.
Jitter refers to small variations in the timing of market data or order transmission. It can affect execution quality, slippage and the reliability of high-speed or systematic trading strategies.
Jobless claims measure the number of people applying for unemployment benefits. Changes in claims can influence expectations for economic growth, labour-market strength and central bank policy.
A joint account is owned by two or more people. Account permissions determine who may trade, withdraw funds or make administrative changes, depending on the provider’s terms.
A joint venture is a business arrangement where two or more parties combine resources for a specific project or commercial objective. Investors may assess its ownership structure, funding needs and potential effect on earnings.
A journal entry records a financial transaction within a company’s accounting system. Analysts may review entries and adjustments when assessing earnings quality and reported financial performance.
The JPMorgan Emerging Markets Bond Index, or EMBI, tracks the performance and spreads of selected emerging-market sovereign debt. Wider spreads may indicate rising credit concerns or weaker global risk appetite.
Jump diffusion is a pricing model that combines normal continuous price movement with occasional sudden jumps. It is used to represent markets where gaps and sharp event-driven moves can occur.
Jump risk is the possibility of a sudden price move that skips available trading levels. Earnings releases, policy decisions and geopolitical events can create gaps that affect stop orders and execution prices.
A junk bond is a bond with a lower credit rating and higher default risk. Issuers generally offer higher yields to compensate investors for taking greater credit exposure.
Jurisdiction risk arises from the laws, regulations and enforcement standards of the country governing an asset, provider or transaction. It may affect leverage, taxation, investor protections and access to funds.
Just-in-time liquidity appears only when automated participants identify a trading opportunity. It may support tighter spreads in calm conditions but disappear quickly during periods of stress or heavy volatility.
A Keltner Channel is a volatility indicator built around an exponential moving average with bands based on average true range. Traders use it to assess trend direction, volatility expansion and possible breakout conditions.
A key level is a price area where buying or selling activity has previously increased. It may align with an earlier high or low, a round number or another widely watched reference point.
A key performance indicator, or KPI, is a metric used to assess trading or investment performance. Common examples include expectancy, drawdown, win rate, average return and risk-adjusted performance.
Key rate duration measures how sensitive a bond or fixed-income portfolio is to interest-rate changes at a specific maturity. It helps separate exposure across different points of the yield curve.
A kicker pattern is a two-candle formation showing a sharp change in market direction. It often appears after unexpected news, although further confirmation may be needed before treating it as a reversal.
A killer candle is an informal term for a large price bar that breaks through a significant level with strong momentum. It may indicate continuation, forced position closures or short-term exhaustion.
A knock-in option becomes active only after the underlying asset reaches a specified barrier. Its value depends on both the final price and whether the barrier was touched during the contract period.
A knock-out option ends if the underlying asset reaches a predetermined barrier. This can reduce the initial premium but may close the exposure during a brief period of volatility.
Know Your Customer, or KYC, refers to identity and risk checks completed by financial service providers. These procedures help meet legal obligations relating to fraud prevention, financial crime and account security.
Kurtosis measures how frequently extreme observations occur within a distribution. In markets, higher kurtosis suggests that unusually large price movements may happen more often than a normal distribution would imply.
The K-ratio evaluates the consistency of investment returns by comparing the slope of cumulative performance with the variability around that trend. A higher ratio generally indicates steadier historical growth.
K-value is a parameter used in some indicators and smoothing calculations. Adjusting it changes the balance between responsiveness and noise, with faster settings reacting more quickly to recent price movement.
A lagging indicator responds after price movement has occurred. Moving averages and MACD are common examples used to confirm trends and reduce short-term market noise.
A leading indicator is designed to signal possible changes before they appear clearly in price. Momentum, volume and sentiment measures may act as leading indicators, though false signals remain possible.
Leverage allows a trader to control a larger position with a smaller amount of capital. It increases exposure to both gains and losses and can lead to rapid account drawdowns.
A limit order instructs the market to buy or sell only at a specified price or better. It offers greater price control but may remain unfilled if the market does not reach the selected level.
Liquidation occurs when a leveraged position is closed because available margin is no longer sufficient to support it. The exact process depends on the product and provider terms.
Liquidity describes how easily an asset can be traded without causing a significant price change. More liquid markets generally offer tighter spreads, deeper order books and more consistent execution.
A liquidity provider supplies buy and sell prices to a market. Banks, institutions and market-making firms may perform this role by maintaining available orders.
A liquidity sweep occurs when price moves rapidly through an area containing multiple orders. The move may trigger stops, fill resting orders and reverse once the available liquidity has been absorbed.
A liquidity trap is an economic condition where very low interest rates and additional monetary stimulus fail to generate stronger borrowing, spending or investment.
A load is a sales charge applied to certain investment funds. It may be paid when units are purchased, sold or held for less than a specified period.
The London Fix refers to scheduled benchmark-setting periods used in markets such as currencies and precious metals. Institutional orders around these times may temporarily increase volume and volatility.
A long-gamma position becomes more directionally exposed as the underlying asset moves further in either direction. It may benefit from larger price swings but is generally affected by time decay.
A long position is opened with the expectation that an asset’s price will rise. The position gains value when the market moves higher and loses value when it falls.
A lookback period is the amount of historical data used in an indicator or calculation. Shorter periods react faster, while longer periods usually produce smoother readings.
Lot size is the standard quantity used to measure a trading position. It affects the position’s notional value, margin requirement and sensitivity to price movement.
A low-float stock has relatively few shares available for public trading. Limited supply can contribute to wider spreads, rapid price changes and increased execution risk.
Maintenance margin is the minimum account equity required to keep a leveraged position open. Falling below this level may trigger a margin call or automatic position closure.
Margin is the capital set aside to open and maintain a leveraged position. It is not a trading fee, but it reduces the amount of free capital available in the account.
A margin call occurs when account equity falls below the required margin level. The trader may need to add funds, reduce exposure or face the closure of open positions.
Margin level compares account equity with used margin, usually as a percentage. It helps indicate how much capacity remains before margin restrictions or liquidation may apply.
Mark-to-market is the process of valuing an open position using the current market price. Changes are reflected in unrealised profit, loss and available account equity.
Market capitalisation is the total market value of a company’s outstanding shares. It is calculated by multiplying the share price by the number of shares issued.
Market depth shows the quantity of buy and sell orders available at different price levels. Deeper markets can usually absorb larger trades with less price movement.
Market impact is the price movement caused by placing or executing an order. Larger trades and thinner markets generally create greater impact and higher execution costs.
A market maker provides buy and sell quotes to support trading activity. It earns part of the bid-ask spread while managing inventory and price risk.
A market order instructs immediate execution at the best available price. It prioritises speed over price control and may experience slippage during fast or illiquid conditions.
Market Profile is a charting method that organises price activity by time and volume. It helps identify value areas, balance, acceptance and rejection.
Market sentiment reflects the overall attitude of participants towards an asset or market. It may be described as bullish, bearish, risk-on or risk-off.
Market microstructure examines how orders, liquidity, spreads and market participants interact. It helps explain short-term price movement and execution behaviour.
The maturity date is when a bond, loan or derivative reaches the end of its term. Principal repayment, settlement or contract expiry may occur on this date.
Mean reversion is the tendency for price or valuation to move back towards a historical average after a significant deviation. The relationship may weaken during strong trends.
The median is the middle value in an ordered data set. It is less affected by extreme observations than the arithmetic mean.
Momentum describes the strength and persistence of price movement in one direction. Momentum strategies seek continuation but remain exposed to sudden reversals.
Monetary policy refers to central bank decisions affecting interest rates, credit conditions and money supply. These decisions can influence currencies, bonds, shares and inflation expectations.
Money flow is an estimate of buying and selling pressure based on price and volume. Positive readings may indicate stronger demand, while negative readings may suggest distribution.
Monte Carlo simulation uses repeated random scenarios to model possible investment or strategy outcomes. It can help estimate return ranges, drawdowns and tail risk.
A naked option is sold without an offsetting position in the underlying asset or another protective option. The strategy may generate premium income but can expose the seller to substantial losses.
Net asset value, or NAV, is the value of a fund’s assets minus its liabilities, usually calculated on a per-unit or per-share basis. An exchange-traded fund may trade above or below its NAV during the session.
Net exposure is the difference between a portfolio’s long and short positions. It indicates overall directional bias after opposing exposures are offset.
Net income is the profit remaining after operating costs, interest, taxes and other expenses are deducted from revenue. It is often referred to as the bottom line.
Negative carry occurs when the cost of maintaining a position exceeds the income it produces. Financing charges, interest-rate differences and storage costs can all contribute.
News risk is the possibility that an announcement or unexpected event causes rapid price movement. Economic releases, company results and geopolitical developments may lead to gaps, wider spreads and slippage.
A no-load fund is an investment fund that does not charge a sales commission when units are purchased or redeemed. Management fees and other operating costs may still apply.
Noise refers to short-term price movement that does not reflect a meaningful change in market direction or fundamentals. Reacting to noise can lead to excessive trading and weak signal quality.
Nominal value is an amount stated without adjusting for inflation. For a bond, it commonly refers to the face value repaid at maturity.
Nominal yield is the annual coupon payment of a bond divided by its face value. It does not account for the bond’s current market price or inflation.
A non-deliverable forward, or NDF, is a currency contract settled in cash rather than through delivery of the underlying currencies. It is often used for currencies with trading or convertibility restrictions.
Non-Farm Payrolls, or NFP, is a monthly US employment report covering most paid workers outside the agricultural sector. It can influence interest-rate expectations, currencies, bonds and equity markets.
A normal distribution is a statistical model in which observations cluster around the average in a symmetrical bell-shaped pattern. Market returns often display more extreme outcomes than this model assumes.
Notional value is the total underlying exposure represented by a derivative or leveraged position. It can be much larger than the margin or capital committed to the trade.
Open interest is the total number of active futures or options contracts that have not been closed or settled. Changes in open interest can provide context on market participation and position activity.
An open position is a trade that has not yet been closed or settled. It remains exposed to price movement, financing costs and changing market conditions.
The opening price is the first recorded trading price of an asset during a market session. It may differ from the previous close when overnight news or order imbalances affect demand.
Operational risk is the possibility of loss caused by system failures, process errors, cyber incidents or human mistakes. Platform outages and incorrect order entry are common examples.
An option chain lists available call and put contracts for an underlying asset by expiry date and strike price. It may include premiums, volume, open interest, implied volatility and Greeks.
An option premium is the price paid by the buyer and received by the seller of an options contract. It reflects intrinsic value, time remaining, volatility and other pricing factors.
Option skew describes differences in implied volatility across strike prices. It can reflect stronger demand for protection, directional positioning or expectations of uneven market risk.
An order book displays visible buy and sell orders at different price levels. It provides a snapshot of available liquidity but may not include hidden or conditional orders.
Order flow analysis examines how buying and selling activity enters the market. Traders may use executed volume, trade direction and liquidity changes to assess short-term pressure.
An oscillator is a technical indicator that moves within a defined or typical range. Indicators such as RSI and Stochastic are commonly used to identify momentum extremes or possible turning points.
An option is out of the money when it has no intrinsic value. A call is out of the money when the underlying price is below the strike, while a put is out of the money when it is above the strike.
Overbought describes a market that has risen rapidly and may be trading above its recent average or momentum range. It does not guarantee an immediate decline.
Overconfidence bias is the tendency to overestimate knowledge, skill or forecasting ability. In trading, it may contribute to excessive position size, weak risk controls and resistance to changing a view.
Overfitting occurs when a strategy is adjusted too closely to historical data and captures random noise rather than a repeatable pattern. Strong backtest results may then fail under live conditions.
Overnight risk comes from holding a position while the market is closed or less liquid. News released during this period can cause price gaps, wider spreads and execution away from expected levels.
Oversold describes a market that has fallen sharply and may be trading below its recent momentum range. The condition can persist during a strong downtrend and does not confirm a reversal.
A parabolic move is a rapidly accelerating price rise driven by strong momentum, speculation or crowded positioning. These moves can reverse sharply once buying pressure weakens.
A passive order rests in the order book and adds liquidity rather than executing immediately. It may provide better price control but does not guarantee a fill.
A payoff profile shows how the profit or loss of a position changes across different market prices. It is commonly used to evaluate options and multi-leg strategies.
The point of control, or POC, is the price level where the highest trading volume occurred within a selected session or volume profile.
Portfolio diversification spreads exposure across different assets, sectors or strategies. It can reduce dependence on a single outcome, though correlations may rise during market stress.
Position sizing determines how much capital is allocated to a trade. It is usually based on account equity, stop distance, volatility and the maximum loss the trader is prepared to accept.
Positive carry occurs when the income generated by a position exceeds its financing or holding costs. Adverse price movement can still outweigh the income received.
Post-trade analysis reviews completed positions to assess execution, decision quality and adherence to a trading plan. The focus is on process rather than the result of one trade.
Price action analysis studies raw market movement, including trends, ranges, momentum and reactions around important levels. It relies less on calculated indicators.
Price discovery is the process through which buyers and sellers establish a market price. It reflects available information, liquidity, expectations and order flow.
Price slippage is the difference between the expected execution price and the price actually received. It is more common during rapid movement or limited liquidity.
A probability distribution describes the possible outcomes of a variable and the likelihood of each one. Traders use distributions to assess volatility, drawdowns and tail risk.
Profit factor compares the total value of winning trades with the total value of losing trades. A result above 1 indicates that gross profits exceeded gross losses over the measured period.
Psychological capital refers to the discipline, resilience and emotional control needed to follow a trading process. It can affect position sizing, patience and reactions to losses.
A pullback is a temporary move against the direction of an established trend. Traders may use it to assess whether the broader trend remains intact.
A put option gives the holder the right, but not the obligation, to sell an underlying asset at a specified strike price before or on expiry.
The put-call ratio compares put activity with call activity using volume or open interest. It is often used to assess options positioning and broader market sentiment.
Qualitative analysis examines non-numerical factors such as management quality, competitive position, industry conditions and business strategy. It is often used alongside financial and statistical analysis.
A quantile divides a data distribution into equal-sized sections. Traders use quantiles to study return ranges, volatility and the probability of more extreme outcomes.
Quantitative trading uses mathematical models, statistical methods and predefined rules to identify and execute trades. Strategies may focus on arbitrage, momentum or mean reversion, but performance can change when market conditions shift.
Quasi-correlation describes a relationship between assets that appears consistent in some market conditions but weakens or reverses in others. This makes stress testing important when strategies depend on correlation.
Queue priority determines which limit orders at the same price are executed first. Orders entered earlier generally receive priority, although exchange rules may differ.
The quick ratio measures whether a company can meet short-term liabilities using its most liquid assets. It excludes inventory and provides a stricter liquidity test than the current ratio.
A quiet period is a restricted communication window before events such as an earnings release or initial public offering. Limited company commentary may increase reliance on market expectations and existing disclosures.
The quote currency is the second currency shown in a currency pair. In EUR/USD, the US dollar is the quote currency and indicates how many dollars are required to buy one euro.
Quote stuffing involves rapidly submitting and cancelling large numbers of orders. The activity can increase market noise, affect displayed liquidity and place pressure on trading systems.
A quoting convention defines how the price of a financial instrument is displayed. Markets may quote instruments using currency values, percentages, yields, points or other standard units.
A range-bound market moves between established support and resistance without forming a sustained trend. Mean-reversion approaches may perform better in these conditions than trend-following strategies.
Rate of return measures the gain or loss on an investment relative to the capital committed. It may be calculated over a specific period and expressed as a percentage.
Realised volatility measures how much an asset actually moved during a historical period. Traders often compare it with implied volatility to assess options pricing.
Relative strength compares the performance of one asset with another asset, sector or benchmark. Persistent outperformance may indicate stronger momentum or investor demand.
Resistance is a price area where selling pressure has previously increased. A confirmed move above resistance may suggest stronger demand, although false breakouts remain possible.
A return distribution shows the range and frequency of past investment or strategy outcomes. Its shape can reveal skew, volatility and exposure to extreme losses.
A reversal is a change in the prevailing direction of a market. Traders may look for confirmation through price structure, volume, momentum or a break of an important level.
Reversion speed measures how quickly a price or spread returns towards its average after moving away from it. Slower reversion can increase holding periods and drawdown risk.
Risk-adjusted return evaluates performance relative to the amount of risk taken. Measures such as the Sharpe ratio and Sortino ratio are commonly used for this purpose.
A risk-off environment occurs when investors reduce exposure to higher-risk assets and favour more defensive markets. Government bonds, reserve currencies and cash may attract stronger demand.
Risk parity allocates portfolio exposure according to each asset’s contribution to overall risk rather than the amount of capital invested. Lower-volatility assets may receive larger allocations.
A risk premium is the additional return investors expect for accepting uncertainty above a lower-risk benchmark. It can reflect credit, liquidity, equity or market risk.
The risk-reward ratio compares the potential loss on a trade with its potential gain. It helps traders assess whether the expected upside justifies the defined downside.
Roll yield is the gain or loss created when a futures position is moved from one expiry into another. It may be positive in backwardation and negative in contango.
A round-trip trade includes both the opening and closing of a position. Commissions, spreads, financing and slippage may all affect the final result.
A runaway gap appears during an established trend and may signal continued momentum. It differs from an exhaustion gap, which can occur near the end of a move.
Rollover is the process of extending a position beyond its current settlement or expiry date. It may involve closing one contract and opening another or applying an overnight financing adjustment.
Settlement is the process of completing a financial transaction by transferring ownership, cash or both between the parties. Timing and procedures vary by market and instrument.
The Sharpe ratio compares excess return with volatility to assess risk-adjusted performance. A higher result indicates stronger historical return per unit of measured risk.
A short position is opened with the expectation that an asset’s price will fall. Losses can increase if the market rises, particularly when leverage is involved.
A short squeeze occurs when rising prices force short sellers to close positions, adding further buying pressure. Crowded positioning and limited liquidity can intensify the move.
A signal is a condition or event used to support a trading decision. It may come from price action, technical indicators, economic data or a rules-based model.
Skewness measures the asymmetry of a return distribution. Negative skew indicates a greater tendency towards extreme losses, while positive skew reflects a greater tendency towards unusually large gains.
Slippage cost is the difference between the expected price of a trade and the actual execution price. Tracking it helps evaluate execution quality across different market conditions.
Smart money is an informal term for capital associated with institutions, professional investors or informed market participants. Traders may attempt to identify its activity through volume, positioning and price structure.
The Sortino ratio measures return relative to downside volatility. Unlike the Sharpe ratio, it focuses only on harmful price movement below a selected target.
The spot market is where assets are bought or sold for near-immediate settlement at the current market price. Currency, commodity and digital asset markets commonly use spot pricing.
A spread trade combines opposing positions in related instruments to benefit from changes in their relative prices. Calendar, commodity and intermarket spreads are common examples.
Standard deviation measures how widely returns vary around their average. Higher readings generally indicate greater historical volatility.
The stochastic oscillator compares an asset’s closing price with its recent trading range. It is commonly used to assess momentum and possible overbought or oversold conditions.
A stochastic process is a mathematical model describing variables that change over time with an element of randomness. It is used in pricing, forecasting and risk modelling.
Stop hunting is an informal term for price movement through areas where stop orders are expected to be concentrated. These moves may trigger rapid execution before price reverses or continues.
A stop-loss order instructs a position to close after price reaches a specified level. It helps limit downside exposure, although gaps and low liquidity may lead to execution at a different price.
A support level is a price area where buying activity has previously increased. Price may hold, consolidate or continue lower if the level fails.
Survivorship bias occurs when analysis includes only assets, funds or strategies that remain active while excluding those that failed or disappeared. This can make historical results appear stronger than they were.
Systematic trading uses predefined rules for entries, exits, position size and risk. Decisions are driven by data and models rather than case-by-case judgement.
Tail risk is the possibility of an extreme market event with a low probability but a severe financial impact. These outcomes often fall outside standard volatility assumptions.
Technical analysis studies price, volume and market structure to identify patterns and possible trading opportunities. It focuses on market behaviour rather than company fundamentals.
Theta measures how much an option’s value may decline as time passes, assuming other factors remain unchanged. Time decay often accelerates as expiry approaches.
The theta decay curve shows how an option’s time value may erode at an increasing rate near expiry. The effect is often strongest for at-the-money options.
Tick size is the smallest permitted price movement for a financial instrument. It affects spread width, order placement and the monetary value of each price change.
A time horizon is the expected period for holding an investment or trade. It influences strategy selection, risk tolerance and the relevance of short-term price movement.
Time in market measures how long capital remains exposed to price movement. Longer exposure may increase sensitivity to financing costs, news and changing market conditions.
Time value is the portion of an option premium above its intrinsic value. It reflects the remaining time until expiry and the possibility of favourable price movement.
Trade expectancy estimates the average gain or loss expected per trade. It combines win rate, average profit and average loss across a series of results.
A trading range forms when price moves between defined upper and lower boundaries without establishing a sustained trend.
A trailing stop moves with the market when price changes favourably. It can protect part of an open gain while allowing the position to remain active.
Transaction cost analysis, or TCA, evaluates execution expenses such as spreads, slippage, fees and market impact. It is used to compare trading performance with an expected benchmark.
A Treasury yield is the return implied by the price of a US government debt security. Yield movements can affect currencies, equities, borrowing costs and asset valuations.
Trend exhaustion occurs when an established move begins losing momentum. Possible signs include weaker follow-through, declining volume and repeated failure to extend beyond recent levels.
Trend following is a strategy that seeks to participate in sustained directional price movement. It commonly uses breakouts, moving averages or momentum rules to define entries and exits.
A trendline connects selected highs or lows on a price chart to illustrate direction. Traders may use it to assess support, resistance and changes in market structure.
Turnover measures the value or volume of an asset traded during a period. In portfolio analysis, it can also describe how frequently holdings are replaced.
An underlying asset is the instrument on which a derivative is based. Shares, indices, commodities, currencies and bonds can all serve as underlying assets for options, futures and CFDs.
Underweight describes a portfolio allocation that is smaller than its benchmark weighting. It may reflect a weaker outlook for a company, sector, region or asset class.
Unrealised profit and loss shows the changing value of an open position before it is closed. The result may increase, decline or reverse as the market price moves.
Unsystematic risk is specific to a company, industry or asset. Earnings results, management changes and regulatory action are examples that may be partly reduced through diversification.
Upfront margin is the capital required before a leveraged position can be opened. The amount depends on the instrument, position size and applicable margin rate.
Upside capture measures how a portfolio or strategy performed relative to a benchmark during periods when the benchmark rose. It is commonly reviewed alongside downside capture.
Upside risk is the possibility that price rises more than expected. It is particularly relevant to short positions, where losses may increase as the market moves higher.
An uptick rule restricts certain short sales when a security is falling. Its purpose is to reduce excessive selling pressure during sharp market declines.
An uptrend is a sustained price movement characterised by higher highs and higher lows. A break in this structure may indicate weakening momentum or a possible trend change.
A user-defined indicator is a custom analytical tool created for a particular trading method. It may combine price, volume, volatility or time-based inputs.
A utility function represents an investor’s preference between risk and potential return. It helps explain why participants may make different decisions when facing the same possible outcomes.
Utilisation rate measures how much available borrowing capacity is currently being used. In securities lending, a high rate may indicate strong borrowing demand or crowded short positioning.
A unit trust pools capital from multiple investors into a managed portfolio. Each investor owns units representing a proportional interest in the trust’s assets.
An unwind is the reduction or closure of an existing position. Large or crowded positions may produce stronger price movement when many participants unwind at the same time.
Value at Risk, or VaR, estimates the maximum expected loss over a defined period at a selected confidence level. It is useful for routine risk monitoring but may understate losses during extreme market events.
Value investing focuses on assets trading below an estimate of their underlying worth. Investors may compare price with earnings, cash flow, assets and long-term business quality.
A value trap is an asset that appears inexpensive based on valuation metrics but continues to weaken because its fundamentals are deteriorating.
Variance measures how widely returns are distributed around their average. It is the square of standard deviation and is commonly used in portfolio and risk calculations.
Vega measures how sensitive an option’s price is to changes in implied volatility. Options with higher vega generally react more strongly when volatility expectations shift.
Velocity describes how quickly price is moving. A sudden increase may reflect stronger momentum, forced position closures or reduced available liquidity.
Venture capital is private funding provided to early-stage companies with high growth potential. Investors accept substantial risk in exchange for possible long-term returns.
A vertical spread combines options with the same expiry but different strike prices. It can be structured with calls or puts to define both potential profit and potential loss.
The VIX measures implied volatility derived from S&P 500 options. It is widely used as an indicator of expected market turbulence and broader risk sentiment.
Volatility measures the size and frequency of price movement over time. It affects position sizing, option premiums, margin requirements and execution risk.
Volatility compression occurs when price ranges become progressively narrower. Traders often monitor these periods for a later expansion in movement.
A volatility regime is an extended period of relatively high or low market movement. Strategies may perform differently as the market shifts between regimes.
The volatility risk premium is the difference between implied volatility and the volatility later realised by the market. It is often considered when evaluating option prices.
Volatility skew describes differences in implied volatility across option strike prices. It may reflect uneven demand for protection or expectations of asymmetric price risk.
Volume is the number of shares, contracts or units traded during a selected period. It helps measure participation, liquidity and the strength behind a price move.
Volume profile shows how much trading occurred at each price level. It helps identify areas where the market showed stronger acceptance or rejection.
Volume-weighted average price, or VWAP, is the average traded price weighted by volume during a session. Traders and institutions use it as an execution benchmark and intraday reference level.
A wash trade involves buying and selling the same asset without a genuine change in ownership or market risk. It can create misleading volume or price activity and is prohibited in regulated markets.
Wave count is an interpretation of price movement based on Elliott Wave theory. Traders use it to map possible market phases, although counts can be subjective and may change as new price data appears.
A wedge is a chart formation created by converging trendlines. Rising and falling wedges may precede a breakout or reversal, but confirmation from price, volume or momentum is often required.
A weighted portfolio assigns different allocations to its holdings based on factors such as market capitalisation, risk, expected return or investment conviction.
A weighted average gives some observations greater importance than others. In finance, it is used in portfolio returns, cost calculations, index construction and pricing benchmarks.
White noise refers to random price movement with little reliable information about future direction. Excessive attention to short-term noise can lead to weak signals and unnecessary trading.
A whipsaw occurs when price changes direction sharply, causing positions to be opened or stopped out shortly before the market reverses again. It is common in volatile or directionless conditions.
A wider spread is an increased gap between the bid and ask prices. It usually reflects lower liquidity, greater uncertainty or rapidly changing market conditions.
Window dressing is the adjustment of portfolio holdings before a reporting date to improve how the portfolio appears. It may temporarily affect demand, volume and asset prices.
Withdrawal risk is the possibility that removing capital weakens a portfolio’s ability to recover from losses or maintain its intended strategy.
Working capital is the difference between a company’s current assets and current liabilities. It helps indicate whether the business can meet short-term operating obligations.
A working order is an active order waiting to be executed. It remains in the market until filled, cancelled or expired under its selected order conditions.
Writing an option means selling an options contract and receiving the premium. The seller takes on an obligation if the buyer exercises the option.
A write-down reduces the recorded value of an asset when its estimated worth falls below its balance-sheet value. It can reduce reported earnings and shareholder equity.
A yard is market slang for one billion units of a currency. The term is commonly used in institutional foreign exchange trading.
Year-on-year, or YoY, compares a data point with the same period one year earlier. It is commonly used for inflation, revenue, earnings and economic growth.
Year-to-date, or YTD, measures performance from the beginning of the current calendar year to the present date.
Yield measures the income generated by an investment relative to its price or value. For bonds, it reflects the relationship between interest payments and the market price.
Yield compression occurs when yields decline, often because demand for an asset increases or financial conditions become easier. It may encourage investors to seek returns in higher-risk markets.
A yield curve plots interest rates across bonds with different maturities. Its shape can provide information about inflation, growth and future interest-rate expectations.
Yield curve control is a monetary policy approach where a central bank targets a specific yield or range for selected government bond maturities.
Yield enhancement refers to strategies intended to increase portfolio income. Option selling, leverage and carry trades may raise income while introducing additional market or tail risk.
Yield sensitivity measures how strongly an asset’s price may react to changes in interest rates. Long-duration bonds and growth shares can be particularly sensitive.
A yield spread is the difference between the yields of two debt instruments. Traders use spreads to assess credit risk, relative value and broader financial conditions.
Yield to maturity, or YTM, estimates the annualised return from holding a bond until maturity, assuming scheduled payments are made and reinvested as expected.
A yo-yo market repeatedly moves higher and lower without establishing a clear direction. These conditions can create false breakouts and frequent reversals.
A Z-score shows how far a value sits from the average, measured in standard deviations. Traders use it to assess unusual price moves, relative mispricing and possible mean-reversion setups.
A zero-coupon bond pays no regular interest and is issued below its face value. The return comes from the difference between the purchase price and the amount repaid at maturity.
Zero-day-to-expiry, or 0DTE, options expire on the day they are traded. They can react sharply to small price moves and experience rapid time decay.
The zero lower bound describes a situation where interest rates are close to zero, reducing the scope for conventional rate cuts. Central banks may then use tools such as asset purchases or forward guidance.
A zero-sum game is a transaction where one participant’s gain equals another participant’s loss before fees and costs. Many derivatives contracts operate this way between counterparties.
The Zigzag indicator filters out smaller price movements to highlight larger market swings. It is mainly used to study structure and past trends because its historical lines may change as new data appears.
A zombie company generates enough cash to continue operating and service debt but has limited capacity to invest, expand or reduce borrowing.
Zonal resistance is a price area where selling pressure has repeatedly increased. It is treated as a broader region rather than one exact price level.
A zone of control is a price area where significant trading activity has occurred over time. It may indicate balance between buyers and sellers before a breakout or rejection.
The Z-spread is the constant spread added across a benchmark yield curve to match a bond’s market price with the present value of its future cash flows. It is used to compare credit and liquidity risk across bonds.
