A trading win rate divides winning trades by the total number of resolved trades. The definition of a win, treatment of partial exits and chosen sample period should be consistent before comparing strategies.
A high win rate can coexist with poor profitability when occasional losses are much larger than frequent gains. Average win, average loss, fees, drawdown and trade count are necessary companions to the percentage.

Win rate is the share of completed trades that made money according to the strategy's rules. It describes how often the strategy won, not how much it earned overall.
For example, 23 winning trades out of 32 would be about a 72 percent win rate. The strategy could still lose money if its nine losing trades were much larger than its winning trades.
