Drawdown: Understanding and Surviving It
Every strategy has drawdowns. The question is whether you can survive yours.
Researched and written by Laurent What Drawdown Actually Means
Drawdown measures the decline from your account's peak value to its lowest point before a new peak is reached. If your account grows to $12,000 and then drops to $9,600 before eventually recovering, the drawdown was $2,400 or 20%.
Every strategy, no matter how good, experiences drawdowns. Even the best hedge funds in the world see 15-20% drawdowns regularly. The question isn't whether you'll have a drawdown. The question is whether you can survive it.
The Recovery Problem
The math of recovery is asymmetric and cruel:
| Drawdown | Gain to Recover | At 1% Risk, 1:2 RR, 45% Win Rate, Approx Trades Needed |
|---|---|---|
| 10% | 11.1% | ~25 trades |
| 20% | 25.0% | ~55 trades |
| 30% | 42.9% | ~95 trades |
| 50% | 100.0% | ~220 trades |
At 50% drawdown, you need to double your remaining capital to get back to where you were. For most traders, this is practically and psychologically impossible.
Setting Your Maximum Tolerance
Before you trade live, answer honestly: "At what drawdown level would I stop trading this strategy?" Write it down. Common answers:
- Conservative: 15% max drawdown. Strategy suspended for review.
- Moderate: 20-25% max drawdown.
- Aggressive: 30%+ tolerable. Only for experienced traders with high conviction in their strategy.
The number must be realistic given your strategy's backtest results. If your strategy showed 18% max drawdown in backtesting, setting a tolerance of 10% means you'll likely abandon a perfectly valid strategy during a normal drawdown.
Key Takeaways
- • Drawdown = peak-to-trough decline in account equity.
- • A 50% drawdown requires a 100% gain to recover. A 25% drawdown requires 33%.
- • Even excellent strategies have 15-25% max drawdowns historically.
- • You must decide your maximum tolerable drawdown BEFORE it happens, not during it.
