Plain-English definitions of common forex terms.
- Ask price
- The price at which you can buy a currency pair. Always slightly higher than the bid.
- ATR (average true range)
- An indicator that measures a pair's average range per candle over a set period, often 14. Traders use it to compare volatility between pairs and to place stops.
- Backtest
- Applying a strategy's exact rules to past price data to see how it would have performed. Useful for rejecting bad ideas; weak evidence that a good-looking idea will work.
- Base currency
- The first currency in a pair. In EUR/USD it is the euro. The price tells you how much of the quote currency one unit of the base is worth.
- Bid price
- The price at which you can sell a currency pair. Always slightly lower than the ask.
- Body (of a candle)
- The thick part of a candlestick, drawn between the open and the close. Its length shows how decisively one side won the period.
- Break-even win rate
- The share of trades you must win to neither gain nor lose, given your reward-to-risk ratio: 1 ÷ (1 + R). At 2:1 it is about 33%.
- Breakout
- When price moves through a support or resistance level that had held before, often with a burst of volume and momentum.
- Broker
- The company that gives you access to the market, holds your deposit and executes your orders.
- Candlestick
- A chart element showing the open, high, low and close of one period, with a body between open and close and wicks to the high and low.
- Carry trade
- Borrowing in a low-rate currency to buy a high-rate one and earn the difference. Profitable in calm markets; unwound violently in fearful ones.
- Central bank
- The institution that sets a country's interest rates and manages its currency, such as the Federal Reserve (US), ECB (eurozone), Bank of England or Bank of Japan.
- Chart pattern
- A recognisable shape made by price over many periods, such as a double top or a flag, that traders use to anticipate what might come next.
- Commission
- A fixed fee some brokers charge per trade, usually quoted per lot, instead of or in addition to a wider spread.
- Commodity currency
- A currency whose country exports a lot of raw materials, so it tends to follow their prices: AUD, NZD and CAD in particular.
- Compensation scheme
- A fund, backed by a regulator, that repays clients up to a limit if a regulated broker fails and cannot return their money.
- Confirmation bias
- Looking for evidence that supports what you already believe and ignoring the rest. In trading, finding a reason to stay in a losing position.
- Confluence
- When several independent reasons point to the same trade: for example a support level, a trend line and an oversold indicator at the same price.
- Consensus (forecast)
- The average of economists' predictions for a data release. The market prices in the consensus beforehand, so the reaction depends on the surprise relative to it.
- Correlation
- How closely two pairs move together, from +1 (always together) to −1 (always opposite). Correlated positions add up to one bigger bet.
- CPI
- Consumer price index: the main measure of inflation, released monthly. One of the most market-moving data points because it steers interest-rate expectations.
- Cross pair (minor)
- A pair of two major currencies without the US dollar, such as EUR/GBP or GBP/JPY. Its price is derived from the two currencies' dollar rates.
- cTrader
- A trading platform popular with ECN brokers, known for modern charting, built-in market depth and C# automation.
- Currency pair
- Two currencies quoted against each other, such as EUR/USD. The price is how much of the second (quote) currency buys one unit of the first (base) currency.
- Curve fitting
- Tuning a strategy's settings until they match past data perfectly. The result usually fails on new data because it learned the noise, not a real pattern.
- Daily loss limit
- A fixed loss, in money or in consecutive losses, at which you stop trading for the day. It prevents one bad session from becoming a disaster.
- Day trading
- A style that opens and closes trades within the same day, usually on 5-minute to 1-hour charts, with no positions held overnight.
- Demo account
- A practice account with virtual money that works like a real one. Used to learn a platform and test ideas without risk.
- Deposit bonus
- Credit added to a deposit, usually with conditions that require a large trading volume before withdrawal. Banned by several regulators because it encourages overtrading.
- Discipline
- Doing what the plan says when you do not feel like it. Built through routine and a daily loss limit, not through willpower alone.
- Drawdown
- The fall in your account from a peak to a low, usually shown as a percentage.
- ECN / STP broker
- A broker that passes your orders through to liquidity providers rather than taking the other side itself.
- Economic calendar
- A schedule of upcoming data releases and central-bank events, with the previous figure, the forecast, and an impact rating.
- Edge
- A repeatable reason a set of trading rules should make more than it loses over many trades, after costs. Measured by expectancy, not by how convincing a setup looks.
- Equity
- Your account balance plus or minus the running profit or loss on open trades.
- Execution
- How and how fast your order is filled: the price you get, the delay, and whether the broker fills it itself or passes it to the market.
- Exotic pair
- A major currency against the currency of a smaller or emerging economy, such as USD/TRY or USD/ZAR. Spreads, swaps and gaps are usually much larger.
- Expectancy
- The average result per trade over many trades: (win rate × average win) − (loss rate × average loss). Positive expectancy is what makes a method profitable over time.
- FOMO
- Fear of missing out: entering a trade late, without a setup, because price is moving and you feel left behind. Usually the worst price of the move.
- Forward test
- Trading a strategy's rules in real time, on demo or very small size, after the backtest. It shows how the rules behave with real spreads, slippage and your own discipline.
- Free margin
- Equity minus the margin locked up by open trades. The amount available to open new positions.
- GDP
- Gross domestic product: the total value of everything an economy produces. Its growth rate is the broadest measure of economic health, but it is published late and revised often.
- Hawkish / dovish
- Hawkish means leaning towards higher rates to fight inflation; dovish means leaning towards lower rates to support growth. Markets react to the lean, not just the decision.
- Indicator
- A calculation drawn on or under the chart, such as a moving average or RSI, that summarises past prices to help you read them.
- Inflation
- The rate at which prices rise. Central banks usually target about 2%. Inflation above target tends to bring rate rises; below target, rate cuts.
- Interest rate (policy rate)
- The rate a central bank sets for lending to banks. It shapes every other rate in the economy and is the strongest single driver of a currency.
- KYC
- Know your customer: the identity and address checks a regulated broker must run before you can deposit or withdraw. Their absence is a warning sign, not a convenience.
- Leverage
- Borrowed exposure from your broker that lets you control a larger position than your deposit. It magnifies both gains and losses.
- Limit order
- An order to buy below the current price or sell above it. It waits until the market reaches your price.
- Liquidity
- How easily you can trade without moving the price. High liquidity means tight spreads and quick fills.
- Losing streak
- Several losing trades in a row. Streaks are a normal product of chance, and their length is what decides how small risk per trade must be.
- Loss aversion
- The tendency to feel a loss roughly twice as strongly as an equal gain. It is why traders cut winners early and let losers run.
- Lot
- A standard trade size. A standard lot is 100,000 units of the base currency; a mini lot is 10,000; a micro lot is 1,000.
- MACD
- Moving average convergence divergence: the gap between a fast and a slow EMA, plotted with its own average (the signal line). Used to read momentum.
- Major pair
- One of the most traded pairs, each including the US dollar: EUR/USD, USD/JPY, GBP/USD, USD/CHF, AUD/USD, USD/CAD and NZD/USD. They usually have the tightest spreads.
- Margin
- The deposit your broker sets aside to keep a leveraged trade open. It is returned when the trade closes.
- Margin call
- A warning from your broker that your equity has fallen close to the margin required. If it keeps falling, positions are closed automatically.
- Market maker
- A broker that takes the other side of your trade itself rather than passing it to the market.
- Market order
- An order to buy or sell immediately at the best available price.
- Maximum drawdown
- The largest peak-to-trough fall in account value over a period. It measures how painful a method is to trade, not just how profitable.
- Mean reversion
- A method that bets a stretched price will move back towards its average, usually by selling near the top of a range and buying near the bottom.
- MetaTrader (MT4 / MT5)
- The most widely offered trading platforms, made by MetaQuotes. MT4 is older and simpler; MT5 is its successor with more timeframes and order types.
- Momentum
- The speed and strength of a price move. Momentum methods trade in the direction of a strong move, often using indicators such as RSI or MACD.
- Moving average
- The average closing price over the last N periods, redrawn each period. It smooths price so the trend is easier to see.
- Neckline
- The level joining the dips of a head-and-shoulders or the peak between a double bottom. A break of it confirms the pattern.
- Negative balance protection
- A rule that a retail client cannot lose more than the money in the account, even if a gap in the market takes a position past the stop.
- Non-farm payrolls (NFP)
- The monthly US jobs report, released on the first Friday of the month. Shows jobs added, the unemployment rate and wage growth. Frequently the most volatile release of the month.
- Overtrading
- Taking more trades than your method produces: trading boredom, trading noise, or trading to feel busy. Costs add up and quality falls.
- Pip
- The standard unit of price movement: 0.0001 for most pairs, or 0.01 for pairs quoted in Japanese yen.
- Pip value
- What one pip is worth in money for a given position size. It depends on the pair's quote currency, so the same lot size can be worth a different amount per pip on each pair.
- Pipette
- One tenth of a pip, the fifth decimal place many brokers display.
- Position size
- How much you trade, in lots or units. Set from your stop loss and the amount you are willing to risk, not the other way round.
- Position trading
- A long-term style that holds trades for weeks to months, driven by big trends and fundamentals. Swap costs matter more than spreads.
- Priced in
- Already reflected in the current price. A widely expected rate rise is priced in, so when it happens the currency may barely move, or even fall.
- Pullback
- A temporary move against the trend before the trend resumes. Many traders wait for a pullback to enter rather than chasing price.
- Quote currency
- The second currency in a pair. In EUR/USD it is the US dollar. Profits and losses are first measured in this currency.
- Range
- A period when price moves sideways between a floor (support) and a ceiling (resistance) without a clear trend.
- Raw spread (ECN) account
- An account with spreads close to the interbank price plus a fixed commission per lot. Usually cheaper than a spread-only account for active traders.
- Regulation
- Supervision of a broker by a financial authority that sets capital, conduct and client-money rules and can fine or shut the firm. The first thing to check about any broker.
- Requote
- When a broker refuses to fill a market order at the price shown and offers a new, usually worse, price instead. Common at dealing-desk brokers in fast markets.
- Resistance
- A price area where rising prices have stalled and turned lower before. A ceiling, until it breaks.
- Revenge trading
- Taking a new trade immediately after a loss to win the money back, usually larger and without a setup. One of the fastest ways to turn a normal loss into a serious one.
- Reward-to-risk ratio
- How much a trade stands to gain for each unit it risks, measured from entry to target against entry to stop. 2:1 means two pips of potential reward for every pip risked.
- Risk per trade
- The amount you would lose if your stop loss is hit, usually expressed as a percentage of the account. Common guidance is 1 to 2%.
- Risk-on / risk-off
- The market's overall mood. Risk-on: investors buy higher-yielding assets and currencies. Risk-off: they sell them and buy safe havens.
- RSI
- Relative strength index: a 0–100 score of recent gains against recent losses. Above 70 is called overbought, below 30 oversold.
- Safe haven
- An asset bought in times of fear because it is expected to hold its value: the US dollar, Japanese yen and Swiss franc among currencies.
- Scalping
- A very short-term style that holds trades for seconds to minutes and aims for a few pips each time. Costs take a large share of every trade.
- Segregated client funds
- Client deposits held in bank accounts separate from the broker's own money, so they cannot be used to run the business and are protected if the firm fails.
- Slippage
- The difference between the price you asked for and the price you got. Common during fast markets and news.
- Spread
- The difference between the bid and the ask price. It is the main cost of trading and is paid the moment a trade opens.
- Stop loss
- An order that closes your trade automatically at a set price to limit your loss.
- Stop order
- An order to buy above the current price or sell below it, triggered when the market reaches that level. Used to enter on breakouts.
- Support
- A price area where falling prices have stopped and bounced before. A floor, until it breaks.
- Swap (rollover)
- The interest paid or earned for holding a position overnight, based on the interest-rate difference between the two currencies.
- Swap-free account
- An account with no overnight interest charged or paid, offered for religious reasons. Brokers often recover the cost through a wider spread or an admin fee.
- Swing high / swing low
- A local peak or trough on the chart. A series of higher highs and higher lows defines an uptrend; lower highs and lower lows a downtrend.
- Swing trading
- A style that holds trades for days to a couple of weeks to catch one swing in price, usually on 4-hour and daily charts.
- Take profit
- An order that closes your trade automatically once it reaches a set profit.
- Tilt
- An emotional state, usually after losses, in which decisions become impulsive and rules are abandoned. The remedy is to stop trading until it passes.
- Timeframe
- The length of time each candle represents, such as M15 (15 minutes), H1 (one hour), H4 or D1 (one day).
- Trading journal
- A record of every trade: the reason, the plan, the result and how you felt. Over time it shows which setups and which behaviours actually make money.
- Trading plan
- A written set of rules covering what you trade, when, how much you risk, what a valid setup is, and how you enter, exit and review.
- Trading session
- The hours when a major financial centre is open: Sydney, Tokyo, London and New York. The market is busiest when sessions overlap.
- Trend
- The overall direction of price over a chosen timeframe: up (higher highs and lows), down (lower highs and lows) or sideways.
- Trend following
- A method that buys in uptrends and sells in downtrends, accepting many small losses for a few large wins when a trend runs.
- Volatility
- How far and how fast a price typically moves. A more volatile pair needs a wider stop, and therefore a smaller position, for the same money at risk.
- Wick (shadow)
- The thin line above or below a candle body, reaching to the high or the low of the period. Long wicks show prices that were rejected.
