Win rate or profit factor? The metric that really matters in signals
Why a 90% win rate can hide a losing system and how to read profit factor, expectancy and loss distribution.
Quick answer
Between win rate and profit factor, profit factor matters more because it measures gross profit against gross loss. A 90% win rate can hide a losing system if the few losses are ten times larger than the wins. The healthy combination is a high win rate, profit factor above 2, maximum drawdown below 20% and losses without extreme tails: The Edge Trading Club discloses 93%, 11.4 and 8.4%.
- Profit factor = gross profit / gross loss; below 1 the system loses.
- Expectancy per trade turns statistical edge into expected value per trade.
- Win rate without drawdown and loss distribution is not a usable metric.
Win rate is the most advertised and least informative metric in isolation. A system with 90% winning trades can be structurally losing if the few losses are ten times larger than the wins. Profit factor and expectancy per trade tell the whole story.
The combination to look for: high win rate, profit factor above 2, maximum drawdown below 20% and a loss distribution without extreme tails. In our panel the top provider discloses a 93% win rate, an 11.4 profit factor and an 8.4% maximum drawdown.
