Drawdown rules are the #1 reason traders fail prop firm challenges. But not all drawdown is calculated the same way — and the type of drawdown dramatically affects how you should trade.
The Three Types of Maximum Drawdown
Your maximum drawdown limit is always measured from your starting balance. It never changes, no matter how much profit you make.
$100K account with 10% static drawdown. Your limit is always $90K. Even if you grow the account to $115K, you can still drop to $90K before failing. You have a full $25K buffer.
Why it's easiest: Making profit increases your safety margin. The more you make, the safer you are.
Your maximum drawdown limit trails your equity high in real-time. Every new high-water mark raises your minimum balance requirement.
$100K account with 10% trailing drawdown. Start: limit is $90K. You make $5K (equity $105K). Now your limit is $94.5K. You make another $3K (equity $108K). Now your limit is $97.2K.
Why it's hardest: Your buffer shrinks as you profit. A winning streak followed by a normal pullback can fail you.
Your maximum drawdown trails based on your end-of-day balance, not real-time equity. Intraday fluctuations don't affect it.
$100K account. During the day you peak at $108K, then close at $104K. Your drawdown limit trails to $94K based on the $104K close — not the $108K peak.
Why it's medium: Gives you room to have intraday drawdowns without penalty, but still penalizes you for closing days at new highs.
Strategy Adjustments by Type
Trading Static Drawdown
- Trade normally — profit gives you more cushion
- No need to "protect" gains aggressively
- Focus on hitting profit target without worrying about drawdown tightening
Trading Real-Time Trailing
- Critical: Lock in profits early in the challenge
- Once you have 5%+ profit, reduce position sizes
- Avoid letting winning trades run too far (triggers higher trail)
- Consider stopping at exactly the profit target, no more
Many traders fail trailing drawdown right after a winning streak. They make 8% quickly, then have a normal 5% pullback — but now that's 5% from the high, leaving only 5% buffer. One more bad day fails them.
Trading EOD Trailing
- Close positions in profit before end of day if possible
- Avoid closing days at new equity highs unless necessary
- If you have a big intraday gain, consider taking some off before close
Daily Drawdown: Similar Concepts
Daily drawdown also varies in how it's calculated:
| Type | Calculated From | Resets |
|---|---|---|
| Balance-Based | Start-of-day balance | Midnight or session close |
| Equity-Based | Highest equity of day | Midnight or session close |
| Higher-of | Higher of balance or equity | Midnight or session close |
Equity-based daily drawdown is trickier because if you're up $2K midday, your daily limit is now measured from that high. Close the day at -$3K from that high and you've hit 5% daily even if you're only -$1K from start of day.
Comparison Summary
| Type | Difficulty | Best For |
|---|---|---|
| Static | Easiest | All traders, especially swing traders |
| EOD Trailing | Medium | Day traders who close daily |
| Real-time Trailing | Hardest | Conservative traders, small targets |
Which Should You Choose?
If you have a choice, prioritize in this order:
- Static drawdown — Always the safest
- EOD trailing — Manageable with proper daily closes
- Real-time trailing — Only if rules/price are significantly better
Some firms offer the same challenge with different drawdown types at different prices. The static version is usually worth the extra cost.
