Risk per trade
Family III · Risk
Not to be confused with trade, forex risk, trade forex.
Risk per trade is the maximum loss a trader accepts on one position, set before the trade is opened. It is usually defined as a percentage of account equity or as a fixed cash sum, and it determines position size when combined with the distance to the stop-loss. The figure is a limit chosen by the trader, not a prediction of the actual loss.
How risk per trade is set and used
Risk per trade is a control variable. A trader decides in advance that no single position may lose more than a chosen amount, then calculates the position size that keeps the loss at or below that amount if the stop-loss is hit.
The calculation uses the distance between the entry price and the stop-loss price. That distance, multiplied by the position size and the value of one point or pip, gives the potential loss. Risk per trade is the ceiling for that result.
Common choices range from a small fraction of a percent to a few percent of account equity. The appropriate figure varies by account size, instrument volatility, strategy and regulatory context, and no single number is universally correct.
Worked example
A trader has an account equity of $50,000 and sets risk per trade at 1%. The maximum acceptable loss is therefore $500. The trade idea uses an entry at 1.2500 and a stop-loss at 1.2450, a distance of 50 pips. If one pip is worth $10 per standard lot, the position size is calculated as $500 divided by (50 pips × $10 per pip) = 1 standard lot.
If the stop-loss is triggered at 1.2450, the loss is $500, which equals the risk per trade. Slippage, gaps or wider spreads can make the realised loss larger than the planned figure.
Limits and variation
Risk per trade is a planned maximum, not a guaranteed outcome. Market gaps, slippage and execution delays can cause the actual loss to exceed the intended amount. The percentage or cash figure a trader selects is a personal or firm-level policy choice; it is not fixed by any universal rule, and different brokers, regulators and trading programmes may impose their own limits or guidelines.
