Why most True Forex Funds traders fail
The 10% drawdown ceiling looks generous in isolation. The math says otherwise. At 2% risk per trade, you bust after just 5 consecutive losers. With a 50% win rate, that sequence happens roughly once every 32 trades — and most evaluations require enough activity that you'll see it.
True Forex Funds's static drawdown is more forgiving than trailing rules, but the daily loss limit is the silent killer. Most evaluation failures happen on a single bad day, not from accumulated drawdown.
The fix is structural, not tactical. Reducing risk per trade from 2% to 1% cuts your expected ruin probability by roughly 75%. Reducing it to 0.5% effectively eliminates rule-based failure for most positive-edge strategies.
