Maximum Drawdown
30-Second Definition
The absolute limit your account equity is permitted to drop from the starting balance before the prop firm terminates your evaluation.
What is Maximum Drawdown?
Maximum Drawdown is the absolute limit your trading account equity or balance is allowed to fall before a prop firm terminates your account. Once your losses touch this limit, the evaluation or funded account is closed instantly, with no exceptions.
Prop firms use this limit to cap their downside risk on funded accounts. In most cases, the maximum drawdown limit ranges between 8% and 10% of the initial account balance.
Types of Maximum Drawdown
- Static Drawdown: Fixed to your initial starting balance. If you make profit, your buffer increases.
- Trailing Drawdown: Trails behind your highest account peak (High-Water Mark). If you make profit, the loss limit moves up with it.
