Who this is for — Anyone who judges a method only by winning trades and risks confusing success frequency with result quality.
Win rate measures the share of trades closed positively out of the total. It is a useful metric, but alone it does not say whether a system truly earns.
In plain terms — Winning often is not enough: how much you gain when you win and how much you lose when you are wrong also count.

How to read it without self-deception
To interpret win rate well, always pair it with:
- payoff-ratio to measure average win/loss ratio.
- expectancy to know expected return per trade.
- profit-factor for aggregate profit/loss ratio.
A high win rate can hide very large losses. A moderate win rate can be excellent with robust payoff.
Example — System A: 70% win rate, payoff 0.6. System B: 45% win rate, payoff 2.1. Over time system B can produce better results despite "winning less often".
Common mistakes
- Seeking only high-probability setups while sacrificing risk/reward.
- Increasing size after short winning streaks.
- Evaluating win rate on samples that are too small.
- Ignoring commissions and slippage in real results.
Card
- What it is: percentage of positive trades out of the total.
- What it does not say: profitability and risk on its own.
- Correct use: read with payoff, expectancy, and drawdown.
