What Is Drawdown in Trading?
Drawdown is the fall in equity from a peak to a later trough. A 20% drawdown leaves $8,000 from a $10,000 peak and needs a 25% gain to recover; a 50% drawdown needs a 100% gain.

Key takeaways
- Drawdown measures how far equity has fallen from its peak: (Peak − Trough) ÷ Peak.
- Recovery is asymmetric: gain needed = 1 ÷ (1 − drawdown) − 1. A 50% loss needs a 100% gain to get back to the peak.
- Maximum drawdown is the largest peak-to-trough fall over a period; it is a risk statistic for strategies and for prop accounts.
- Trailing drawdown follows a high-water mark upward and never relaxes — common on prop firm accounts.
- Use the drawdown calculator for recovery maths and the prop firm drawdown calculator for rule-based floors.

What drawdown means
In trading, drawdown is the decline in account equity from a previous high to a subsequent low, before a new high is made. It describes depth of loss relative to a peak, not relative to your first deposit alone.
If equity peaks at $12,000 and later falls to $9,000, the drawdown is ($12,000 − $9,000) ÷ $12,000 = 25%. Traders also quote drawdown in money ($3,000) when a prop firm rule is written in dollars.
Equity includes open profit and loss. Balance only includes closed trades. Intraday drawdown on equity can be larger than the drawdown you see on the closed balance.
Why recovery takes a larger gain
| Drawdown | Balance left from $10,000 | Gain needed to recover |
|---|---|---|
| 10% | $9,000 | 11.1% |
| 20% | $8,000 | 25.0% |
| 25% | $7,500 | 33.3% |
| 33% | $6,700 | 49.3% |
| 50% | $5,000 | 100.0% |
| 75% | $2,500 | 300.0% |
That asymmetry is why position sizing and losing streaks matter more than average wins. The risk management guide connects drawdown depth to risk per trade.
Maximum drawdown
Maximum drawdown (max DD) is the largest peak-to-trough decline over the period you measure — a backtest, a year of live trading, or the life of a prop account. It is a single statistic: the worst historical scar, not the average scar.
Two strategies with the same average return can have very different max drawdowns. Investors and prop firms care about max DD because it estimates how much pain the rules (or the trader) must tolerate.
What is trailing drawdown?
Trailing drawdown is a loss limit that moves up with a high-water mark and does not move back down when equity falls. If the trail is $2,000 on a $50,000 account and equity reaches $53,000, the floor becomes $51,000. A later drop to $51,000 breaches the rule even though you are still above the original $48,000 static floor.
Variants:
- Equity trailing — follows the highest equity, including open profit.
- Balance trailing — follows the highest closed balance only.
- End-of-day trailing — updates only at the daily close.
Prop firm trailing drawdown often locks when the floor reaches the starting balance. After that, the limit behaves like a static floor. See the prop firm guide for how that sits inside funded accounts.
Static vs trailing max drawdown
| Static max drawdown | Trailing max drawdown | |
|---|---|---|
| Floor | Fixed from start (e.g. start − 10%) | Start − limit, then rises with peaks |
| After a winning run | Same floor as day one | Tighter floor; less room to give back profits |
| Common in | Some prop 2-step static accounts; personal risk stats | Many 1-step and futures-style prop accounts |
Neither is "safer" in the abstract. Trailing limits punish giving back open or closed gains; static limits punish falling far below the start. Know which one your rules use before you size the next trade.
Keeping drawdowns smaller
- Risk a small, fixed fraction of equity per trade so a streak of losses cannot dig a deep hole. The position size calculator turns that fraction into lots.
- Respect correlation — three highly correlated positions are closer to one large risk than three independent ones.
- Stop adding size after losses until equity stabilises; martingale deepens drawdowns.
- On prop accounts, size from remaining room to the daily and max limits, not from the starting balance.
Frequently asked questions
What is drawdown in trading?
Drawdown is how far equity has fallen from a previous peak to a later trough, usually expressed as a percentage of the peak. A fall from $10,000 to $8,000 is a 20% drawdown.
What is maximum drawdown?
Maximum drawdown is the largest peak-to-trough decline over the period you measure. It summarises the worst historical loss from a high, not the average loss.
What is trailing drawdown?
A trailing drawdown limit follows your high-water mark upward and never moves back down. As you make money the floor rises, so giving back profits can breach the limit even if you are still above the original starting balance.
How much gain do I need to recover from a drawdown?
Gain needed = 1 ÷ (1 − drawdown) − 1. A 20% drawdown needs 25% to recover; a 50% drawdown needs 100%. The drawdown recovery calculator prints the figure for any depth.
What is prop firm trailing drawdown?
On many prop accounts the maximum loss trails equity or balance and may lock at the starting balance. Breach ends the account. Use the prop firm drawdown calculator with your firm's rule type rather than a generic percentage.
