Drawdown is a trader's worst enemy. It's not just losing money — it's losing faith in the strategy while the numbers keep going down. Understanding what it means, what's normal, and how to handle it emotionally is the difference between a long career and a quick blow-up.
This guide covers types of drawdown, acceptable values, psychological recovery, and the real numbers of profitable traders.
What is drawdown
Drawdown (DD) is the maximum loss from an equity peak to the subsequent low. In other words: how much your account has dropped from its all-time high.
Example: your account goes $10,000 → $12,000 → $10,500 → $11,000. Drawdown = $12,000 - $10,500 = $1,500 = 12.5%.
Drawdown is always measured from the peak, not from the initial balance.
The 3 types of drawdown
1. Maximum Drawdown (MDD)
The largest drawdown ever recorded by the strategy. It's the single most important number for evaluating a system.
Calculated on the full equity curve, not on the daily balance.
Example: equity curve goes from $10k to $15k to $11k to $14k to $9k. MDD = peak-to-trough largest distance. It tells you that historically your strategy can lose $5k from peak ($15k → $10k touched later) even if you're now at $14k.
2. Daily Drawdown
Maximum loss in a single trading day. Important for prop firms (FTMO has a 5% daily DD limit).
It's calculated from midnight equity to the lowest equity of the day, including open trades (floating P&L).
3. Statistical drawdown (Monte Carlo)
The worst likely drawdown you could see in the future, calculated by simulating thousands of different scenarios on your historical trades.
Example: your historical MDD is 12%. Monte Carlo says that with 95% probability you won't exceed 18%, but with 5% you could see 25%. Helps set realistic expectations.
How much drawdown is "normal"
It depends a lot on the strategy:
Conservative strategies (mean-reversion, scalping with tight stops)
- Typical MDD: 5-12%
- Daily DD: 1-2%
- Recovery time: 1-2 months
Standard strategies (day trading, swing)
- Typical MDD: 10-20%
- Daily DD: 2-4%
- Recovery time: 2-4 months
Aggressive strategies (breakout, news trading)
- Typical MDD: 20-35%
- Daily DD: 3-7%
- Recovery time: 3-6 months
If your strategy has MDD > 30% in a backtest of 500+ trades, the position sizing is too aggressive. Reduce risk per trade by 30-50%.
The fundamental rule: drawdown vs recovery
Drawdown is asymmetric — recovering it costs more than losing the same amount. The math:
- DD 10% → need +11% to recover
- DD 20% → need +25%
- DD 30% → need +43%
- DD 40% → need +67%
- DD 50% → need +100%
- DD 60% → need +150%
- DD 70% → need +233%
- DD 80% → need +400%
- DD 90% → need +900%
Hence the golden rule: protect capital above all else. A 50% DD is never recovered with the same strategy that generated it.
What to do when you're in drawdown
Step 1: Recognize the type of drawdown
Normal drawdown (within historical MDD) → keep trading with the same size, it's variance.
Abnormal drawdown (beyond historical MDD) → something is off. Temporary stop, strategy review.
Step 2: Reduce size
When drawdown exceeds 50% of historical MDD, halve your size:
- Historical MDD 15% → when current DD exceeds 7.5%, switch from 1% risk to 0.5%
- Keep trading but with half the exposure
- When the account recovers to the previous peak, return to normal size
Step 3: Forensic analysis
Open the journal. Which setups generated the DD? Are they trades outside your strategy? Did you break rules? Did you change style without noticing?
Out of 10 traders in deep drawdown, 8 find out they made trades outside the system. The strategy wasn't the problem, the trader was.
Step 4: Pause if necessary
If the DD exceeds 75% of historical MDD, stop for 1 week. Only do backtests (no live). Re-analyze everything. Get back in only when you have clarity.
Psychological vs financial drawdown
Financial drawdown is one thing. Psychological drawdown is 10x more important.
Experienced traders say: "I lost 20% of the account and wasn't scared." Beginners lose 5% and start making emotional trades, worsening the DD.
The difference:
- The pro knows the expected MDD of their strategy → sees 15% and says "normal"
- The beginner has no expectations → sees 8% and panics
Solution: do extensive backtests of your strategy before going live. Know your historical MDD, your average recovery time, the frequency of DDs. When they happen live, you know what to expect.
How to prevent catastrophic drawdowns
1. Conservative position sizing
Risk 0.5-1% per trade, never above. See the position sizing guide.
2. Correlation awareness
Don't open 3 EUR/anything trades at the same time. They're ~80% correlated. If EUR drops, you lose all 3 together. Limit to max 1 trade per similar "risk factor".
3. Daily loss limit
Impose this: if I lose X% in a day, I close the terminal. Typical: 2% of the account. Prevents an emotional chain of losses after the first stops.
4. Weekly review
Every Sunday you check the numbers. If weekly DD exceeds 3%, write in the journal what happened and what you'll change.
5. Diversification
Don't put everything on a single asset. If you only trade EURUSD and there's a black swan on EUR, you're ruined. Spreading across 3-5 uncorrelated instruments reduces overall volatility.
Drawdown on prop firms
On FTMO, FundedNext, The5ers etc., drawdown determines survival:
- Daily DD limit: typically 5%. If you lose more than 5% in 24h, challenge failed.
- Max DD limit: typically 10% (FTMO) or 4% static (The5ers). Beyond = challenge failed.
To stay below: risk 0.5% per trade max. With consecutive SL hits, you lose 2 trades = 1% of the day → safe.

In summary
- Drawdown = loss from the peak, not from the initial balance
- Types: Maximum, Daily, Statistical (Monte Carlo)
- Asymmetry: recovery costs more than the drawdown itself
- MDD < 20% is "healthy" for standard strategies
- When in DD: reduce size, analyze journal, possibly pause
- Prevention: position sizing, no correlation overlap, daily loss limit
- Prop firms: risk 0.5% per trade to stay under the limits
Knowing your expected drawdown = surviving the first rough patch (which always comes).
