Pip

A pip (percentage in point) is the standard unit for measuring price movement in a forex pair. For most currency pairs a pip equals 0.0001 of the quote currency; for pairs quoted in Japanese yen a pip equals 0.01. Some brokers provide fractional pips (pipettes) equal to one-tenth of a pip (e.g., 0.00001). Pip value varies with the pair, account currency and trade size: for many USD-quoted pairs one pip on a standard 100,000-unit lot is $10. Example: EUR/USD moving from 1.1500 to 1.1501 is a one-pip move. For USD/JPY moving from 110.00 to 110.01 is a one-pip move. Traders use pips to express spreads, stop-loss and take-profit levels, and profit/loss, but pips alone do not guarantee trading success or profits.

Pips appear everywhere in forex trading: price quotes, spread displays, order entry fields and historical price data. Brokers show bid/ask spreads in pips (or pipettes) and platforms expose pip-based stop-loss and take-profit inputs. Charts and tick data record moves in pips, and performance metrics like average win or loss are often expressed in pips per trade. In backtests and optimisation, aggregated pip results allow comparison across instruments. Because pip magnitude differs for JPY pairs and due to account currency conversion, traders must convert pip moves into their account currency to measure actual monetary risk and returns. Pips are a fundamental unit for communication and risk calculation but are one component of broader trade management.

Automated strategies (EAs) use pips to set and manage stops, take-profits, trailing stops, grid spacing and volatility filters. EAs calculate position size by combining desired monetary risk, stop-loss in pips, and pip value to determine lot size. Example: if pip value = $10 (standard lot) and an EA wants to risk $100 with a 20-pip stop, it sizes the trade to 0.5 lots (100 ÷ (20×10)). EAs may also adjust entry/exit logic based on pip-based spreads or filter trades when spreads exceed a pip threshold. Always test pip-based rules in demo/backtest environments; pip calculations support risk control but do not guarantee profit.
