Drawdown is the single most important concept in trading risk management. Yet many traders don't fully understand its implications.
What Is Drawdown?
Drawdown measures the peak-to-trough decline in your trading account. If your account peaks at $110,000 and then drops to $104,000, your drawdown is $6,000 or 5.45%.
Types of Drawdown
Static (Fixed) Drawdown
Your maximum loss is calculated from your starting balance. If you start with $100,000 and have a 10% max drawdown, you can lose up to $10,000 total, regardless of how much profit you've made.
Example: Start $100K → Make $15K profit ($115K) → You can still drop to $90K before violation.
Trailing Drawdown
The drawdown limit follows your highest account balance. This is significantly harder to manage.
Example: Start $100K → Make $15K profit ($115K) → Drawdown trails up → You can now only drop to $105K.
End-of-Day (EOD) Trailing
Same as trailing but only updates at market close, not intraday. This gives you more breathing room during volatile sessions.
The Math That Kills Accounts
Recovery from drawdown is asymmetric:
| Drawdown | Recovery Needed |
|---|---|
| 10% | 11.1% |
| 20% | 25% |
| 30% | 42.9% |
| 50% | 100% |
A 50% drawdown requires a 100% gain just to break even. This is why risk management trumps everything.
Practical Drawdown Rules
- Risk per trade: Never more than 1-2% of account
- Daily loss limit: Stop trading after losing 3-4%
- Correlation risk: Don't take 5 correlated trades simultaneously
- Scale down after losses: Reduce size after consecutive losses
Drawdown in Prop Trading
Different prop firms handle drawdown differently. Some use static drawdown (more forgiving), others use trailing (harder). Understanding which type your firm uses before starting is critical.

Key Takeaway
The best traders aren't the ones with the highest win rate — they're the ones who manage drawdown effectively. Protect your capital first, profits follow.
