Dynamic Drawdown is a drawdown model where the maximum allowed loss rises as the account balance or equity increases. The drawdown floor moves up every time the account sets a new high, which locks in part of a trader's profit and tightens how far the account can fall before it breaches. Traders and prop firms also call this trailing drawdown. Forex-focused firms often use "dynamic drawdown" as the official name for the same rule.
Static drawdown stays fixed at one level for the life of the account. Dynamic drawdown does not. The floor resets upward at every new equity or balance high, so risk control gets stricter the more the account earns.
- Also called trailing drawdown industry-wide. Forex-focused firms often label it "dynamic drawdown" specifically.
- The floor only moves up. A losing stretch never lowers it back down.
- Most firms set dynamic drawdown between 4% and 10% of the account's highest recorded balance or equity.
- Instant funded accounts almost always use dynamic drawdown. Evaluation accounts more often use static drawdown once a trader passes. See instant funding vs. evaluation for the full breakdown.
Dynamic Drawdown vs. Static Drawdown
Dynamic drawdown and static drawdown handle profit in opposite ways. Static drawdown keeps the loss floor fixed at the starting balance no matter how much the account earns. Dynamic drawdown moves that floor up every time the account sets a new high, so profit tightens the account's own safety margin instead of widening it.
| Static Drawdown | Dynamic Drawdown | |
|---|---|---|
| Floor moves | Never | Up, at every new high |
| Best for | Traders who want a fixed safety margin | Firms rewarding steady, low-volatility growth |
| Common on | Evaluation accounts | Instant funded accounts |
Why Dynamic Drawdown Matters in Prop Trading
Dynamic drawdown rewards traders who grow an account steadily and protects the firm's capital at the same time. As profit climbs, a trader loses the option to give back all early gains and still survive. Dynamic drawdown forces consistent execution instead of one aggressive profit run.
Traders who understand dynamic drawdown plan exits and position sizing around the moving floor instead of the starting balance. The floor tightens every time the account gains, so a large floating loss gets riskier the more profitable the account becomes. A trader who tracks the current floor avoids breaching the account by accident during a winning stretch.
How Dynamic Drawdown Is Calculated
Most firms calculate the new floor as a percentage of the account's highest recorded balance or equity, not the starting balance. Every time the account sets a new high, the firm multiplies that new high by the drawdown percentage and sets the floor at the difference.
Drawdown floor = highest recorded balance or equity − (drawdown percentage × highest recorded balance or equity)
Some firms lock the floor once it reaches the starting balance and stop it moving further. Others keep trailing the floor for the life of the account. FundedTrading.com's prop firm drawdown rules guide breaks down which model applies at specific firms, since the two produce very different risk profiles at higher balances.
Example of Dynamic Drawdown
A trader starts a $100,000 account with a 5% dynamic drawdown. The account reaches a peak equity of $110,000. The drawdown floor moves up to $104,500 ($110,000 minus 5% of $110,000). If equity later falls below $104,500, the account is breached, even though the balance still sits above the original $100,000 starting balance.
The same math holds at larger account sizes. FTUK's 1-Step account uses an 8% dynamic drawdown. At a $640,000 peak balance, the floor sits $51,200 below that peak. A trader who reaches the peak and gives back $51,200 breaches the account, no matter how much profit came before it. See FundedTrading.com's guide to the best prop firms for scaling for how this plays out across funded milestones.
Common Mistakes with Dynamic Drawdown
Most dynamic drawdown breaches happen after a winning streak, not a losing one. A trader locks in a new equity high, gives back a normal pullback that would have been safe under a static drawdown, and the account closes anyway.
- Treating the floor as fixed to the starting balance instead of the account's last recorded high
- Holding open floating losses on an equity-based drawdown account without checking the current floor
- Assuming a withdrawal lowers the drawdown percentage; most firms instead recalculate the floor against the balance left after the withdrawal
Dynamic Drawdown FAQ
Is dynamic drawdown the same as trailing drawdown?
Yes. Dynamic drawdown and trailing drawdown describe the same moving loss floor. Forex-focused firms tend to use "dynamic drawdown" in their official rules. Futures-focused firms tend to use "trailing drawdown." Both terms describe a floor that only moves up.
Does dynamic drawdown reset after a withdrawal?
Most firms recalculate the dynamic drawdown floor against the account's balance right after a withdrawal instead of lowering the drawdown percentage itself. Check the specific firm's payout rules before withdrawing close to the floor.
Is dynamic drawdown based on balance or equity?
Dynamic drawdown can be based on either, depending on the firm. A balance-based version only counts closed trades. An equity-based version also counts open floating profit and loss, which moves the floor in real time during a trade.
