Risk management, not prediction, is what keeps a trader alive. Define risk in R — one R is the money lost if the stop is hit. A trade targeting three times its stop is a 3R trade.
| Drawdown | Gain needed to recover |
|---|---|
| 10% | 11% |
| 25% | 33% |
| 50% | 100% |
| 75% | 300% |
Expectancyjs
function expectancy(winRate, avgWinR, avgLossR = 1) {
return winRate * avgWinR - (1 - winRate) * avgLossR;
}
// 40% win rate at 3R
console.log(expectancy(0.4, 3).toFixed(2) + "R per trade");- Risk a fixed small percentage (0.5-1%) per trade.
- Every position has a stop loss before it is opened.
- Cap total risk across correlated pairs (EUR/USD and GBP/USD move together).
- Set a daily and weekly loss limit, then stop trading.
A 40% win rate at 3R is highly profitable. A 90% win rate at 0.1R is not. Win rate alone means nothing without R.
