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.

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.
