Trading terms, explained plainly
38 terms traders meet every day, from risk per trade to funding rates, each in one or two sentences with a link to the full guide.
Risk and position sizing
- Risk per trade
The amount you accept losing if the stop-loss is hit, usually set as a fixed percentage of the account, such as 1%.
Related guide: Position sizing: the 1% rule, worked through- Position size
How much of a coin you buy or sell. With a fixed risk it equals the amount at risk divided by the distance from entry to stop.
Related guide: Position sizing: the 1% rule, worked through- R (R-multiple)
A result measured in units of the initial risk. If you risk 100 USDT, a 200 USDT profit is +2R and a full stop-out is −1R.
Related guide: Risk-reward and expectancy: why win rate is not enough- Risk-reward ratio (R:R)
The planned profit to the target divided by the planned loss to the stop. A 1:2 trade aims to make twice what it risks.
Related guide: Risk-reward and expectancy: why win rate is not enough- Win rate
The share of trades that end in profit. On its own it says little; it only matters together with the average win and loss.
Related guide: Risk-reward and expectancy: why win rate is not enough- Expectancy
The average result per trade over many trades, usually in R: win rate × average win − loss rate × average loss.
Related guide: Risk-reward and expectancy: why win rate is not enough- Drawdown
The fall from an account's peak to a later low, in percent. A 40% drawdown needs a 67% gain to get back to the peak.
Orders and execution
- Market order
An order filled immediately at the best available price. Fast, but the fill can be worse than the last price in a thin or fast market.
- Limit order
An order to buy at or below, or sell at or above, a price you set. It may not fill if price never reaches it.
- Stop-loss
An order that closes the position when price reaches a level where the trade idea is proven wrong, capping the loss.

An order that closes all or part of a position at a planned target price.
- Slippage
The difference between the price you expected and the price you actually got, common with market and stop orders in fast moves.
- Spread
The gap between the best buy (bid) and best sell (ask) price. Wider spreads make every trade start a little behind.
Technical analysis
- Candlestick
A bar showing the open, high, low and close for one period. A green body means the close was above the open, red means below.
- Trend
The general direction of price: higher highs and higher lows in an uptrend, lower highs and lower lows in a downtrend.
- Support and resistance
Price zones where buying (support) or selling (resistance) has repeatedly stopped a move. Best drawn as zones, not single lines.
Related guide: Support and resistance: draw zones, not lines- Volume
How much was traded in a period. Rising volume on a breakout suggests real participation; a move on thin volume is easier to reverse.
Related guide: Reading volume alongside price- RSI (Relative Strength Index)
A momentum indicator from 0 to 100 that compares recent gains with recent losses, usually over 14 periods.
Related guide: RSI without the myths: what 70 and 30 really tell you- EMA (exponential moving average)
An average of recent closing prices that gives more weight to the latest ones. The 50- and 200-day EMAs are common trend filters.
- MACD
The difference between the 12- and 26-period EMAs, shown with a 9-period signal line. The histogram is the gap between the two.
- ATR (Average True Range)
The average size of one candle's range, including gaps, usually over 14 periods. It measures volatility in price units.
Related guide: Setting stops with ATR: room for the trade, fixed risk- VWAP
The volume-weighted average price over a period: the average price paid, with heavily traded prices counting more.
- Fibonacci retracement
Levels drawn between a swing high and low, such as 38.2%, 50% and 61.8%, used to mark where a pullback might pause.
- Divergence
When price and an indicator such as RSI move in opposite directions, for example a higher high in price with a lower high in RSI.

Futures and leverage
- Long and short
A long position profits when price rises; a short position profits when price falls.
- Perpetual futures
A futures contract with no expiry date. A periodic funding payment keeps its price close to the spot market.
Related guide: Funding rates: the hidden cost of perpetual futures- Funding rate
The periodic payment between longs and shorts on perpetual futures. When it is positive, longs pay shorts.
Related guide: Funding rates: the hidden cost of perpetual futures- Leverage
Trading a position larger than the margin you post, such as 10×. It reduces the margin needed, not the loss if price moves against you.
Related guide: Leverage and liquidation: how futures losses really happen- Margin
The collateral you post to open and keep a leveraged position.
- Liquidation
The forced closing of a leveraged position when losses use up the margin down to the maintenance level.
Related guide: Leverage and liquidation: how futures losses really happen- Mark price
The reference price an exchange uses for unrealised profit and liquidation, built from spot index prices to resist short spikes.
- Open interest
The total value of futures positions still open. Rising open interest means new money is entering positions, not which side will win.
Market and sentiment
- Market capitalisation
Price multiplied by circulating supply. It measures a coin's size, not how easily it can be traded.
- Bitcoin dominance
Bitcoin's share of the total crypto market capitalisation. A rising share often means money is moving away from smaller coins.
- Stablecoin
A token designed to hold a steady value, usually 1 US dollar, such as USDT or USDC.
- Volatility
How much price moves. Often quoted as the annualised standard deviation of daily returns.
- Liquidity
How easily you can trade without moving the price. Deep order books and tight spreads mean good liquidity.
- Fear & Greed Index
A daily 0–100 sentiment score for Bitcoin built from volatility, momentum, social data, dominance and search trends.
