Win rate is the percentage of resolved trades that finished as winners. It is simple to calculate, but interpreting it in isolation can be misleading.

Win rate formula
A common convention is wins ÷ (wins + losses) × 100, excluding break-even trades from the denominator. Platforms may handle break-even trades differently, so use one definition consistently.
Why a high win rate does not necessarily mean higher profitability
If average winners are small and average losses are very large, a high hit rate can still produce negative expectancy. Review win rate alongside average win, average loss, Profit Factor, expectancy and trading costs.
Segment your win rate
An overall percentage can hide large differences. Compare it by strategy, market, timeframe, direction, session and plan adherence. Always display the number of trades in each group as well.
Be careful with small samples
An 80% win rate over five trades means something very different from 58% over two hundred. Do not change rules based on win rate without considering sample size and result variability.
