Win Rate vs Risk-Reward
A strategy can win often and still lose money if average losses are much larger than average wins.
Why win rate can be misleading
Win rate tells you how often trades finished as winners, but it does not tell you how large those winners were compared with losses.
Why payoff matters
A lower win rate can still produce a positive historical result when average winning trades are sufficiently larger than average losing trades.
Review both together
When reviewing completed trading history, win rate and payoff should be interpreted together rather than as isolated statistics.
