Win Rate vs Risk-Reward: What Actually Matters in Trading

Traders often ask, "What win rate do I need?" The more useful question is: "What is my expected value per trade?"

Why win rate can mislead

A strategy can win 80% of trades and still fail if the occasional losses are too large. Another strategy can win 45-55% and still grow steadily if winners are larger than losers and risk is controlled.

The three-part model

Win rate (frequency of winners)
Risk-reward ratio (size of winners vs losers)
Risk management (position sizing and drawdown control)

Simple example

Strategy A: 75% wins, average win +1R, average loss -4R → fragile.
Strategy B: 55% wins, average win +1.8R, average loss -1R → often healthier.

What to track weekly
