Win rate is the fraction of trades that closed at a profit, expressed as a percent. A 60% win rate means 6 out of every 10 trades made money. It is the most cited and most misleading single statistic about a trading system.
Win rate in isolation says nothing about whether a strategy is profitable. A 90% win-rate strategy with average winner 0.5R and average loser 5R has negative expectancy. Combine win rate with average win, average loss, and trade frequency to assess real edge — that combined metric is expectancy.
Different strategies cluster at different win rates: mean-reversion at 60–80% with small RR, trend-following at 30–50% with high RR. Comparing win rates across styles is meaningless.
Formula
win_rate = winning_trades / total_trades
Esempio
Out of 100 trades, 55 were winners. Win rate = 55%. Profitability depends on the size of those winners vs. the size of the 45 losers.
