Win Rate

The percentage of trades that close in profit — meaningful only alongside risk-reward.

Win Rate, explained

Win rate is simply the share of your trades that end as winners: 55 wins from 100 trades is a 55% win rate. On its own it says very little about whether a strategy makes money.

Win rate must always be read with risk-reward. A 40% win rate is highly profitable at 1:3, while an 80% win rate can still lose money if the rare losers are huge. Chasing a high win rate by using tiny targets and wide stops is a classic trap that looks great on paper and bleeds in practice.

Sample size is the other catch. A 70% win rate over twelve trades tells you almost nothing — variance alone can produce streaks in either direction. It takes a few hundred trades for a win rate to stabilise into something you can trust, which is why short, glowing track records should be treated with caution.

There is also a psychological cost to high-win-rate styles: the occasional large loss, when it comes, feels devastating after a long run of small wins. Many traders abandon a perfectly sound system precisely because its rare losers hurt more than its frequent winners reward.

On the desk we never quote win rate alone. It only becomes meaningful next to average risk-reward and a decent sample, which together feed expectancy — the number that actually predicts whether the approach makes money over time.

Frequently asked questions

Is a higher win rate always better?
No. Win rate is meaningless without risk-reward. A 40% win rate at 1:3 beats an 80% win rate at 1:0.25. Chasing a high win rate with tiny targets and wide stops is a common way to look good yet lose money.
How many trades do I need to judge a win rate?
Usually a few hundred. Over a handful of trades, variance dominates and the win rate is unreliable. Short, impressive track records often reflect luck rather than a stable, repeatable edge.
