Expectancy
Average R per trade: (win rate x avg win R) - (loss rate x avg loss R). Positive expectancy is the whole game.
40% win rate x 3R avg winner, -1R avg loser = +0.6R per trade. Over 100 trades: +60R. At 1% risk per trade = 60% account growth before compounding. Expectancy is the only metric that matters - everything else is decoration.
