Drawdown in prop trading is the maximum your account may fall from its high point before the firm closes it. It is the leash on every evaluation and funded account: cross the line and the account terminates, positions close, and the fee is gone.

The definition only becomes useful once you know the reference point. Firms measure from the starting balance (static), from your equity peak as it rises (trailing), or from the peak but only updated once per day (end-of-day). The same "10% drawdown" can be three very different constraints depending on that choice.

Worked example: on a $100,000 account with a 10% static drawdown, your floor is $90,000, period. With a trailing drawdown, grow to $110,000 and the floor climbs to $99,000 - a $10,000 gain that shrinks your room to $11,000 instead of the $20,000 a static floor would leave.

Recovery maths is why the number dominates: a 10% drawdown needs an 11.1% gain to recover; a 50% drawdown needs 100%. The full treatment: maximum drawdown explained, the variants in drawdown types, and the daily cousin in daily loss limit.

Frequently Asked Questions

Why is a 50% drawdown harder to recover than a 10% one?

A 50% drawdown requires a 100% gain to recover, while a 10% drawdown only needs 11.1%. Recovery math is exponential. At 30% drawdown you need 42.9% to break even. This is why prop firms cap drawdown at 10-12% rather than higher percentages.

What is the 3-5-7 rule in forex?

The 3-5-7 rule suggests risking 1-3% per trade, keeping total open risk at 5% or less, and limiting single market exposure to 7%. It is a general risk guideline, not a prop firm rule, but following it naturally keeps you within most max drawdown limits.

What is a good maximum drawdown?

For prop firm trading, keeping your actual drawdown under 5% is excellent. Most firms allow 10-12%, but staying well below the limit demonstrates strong risk management and gives you a buffer for unexpected market events.

Is maximum drawdown calculated on balance or equity?

It depends on the firm and drawdown type. Static drawdown is typically calculated on starting balance. Trailing drawdown follows your highest equity. Some firms include floating losses in their calculation, making equity the relevant measure.

What happens when you breach maximum drawdown?

Breaching maximum drawdown results in immediate and permanent account closure. All positions are closed automatically, the challenge is terminated, and there is no refund or appeal. It is the final rule with no second chances.

What is the difference between daily drawdown and maximum drawdown?

Daily drawdown resets every day and limits your loss within a single session. Maximum drawdown is cumulative across the entire challenge or funded period. You can breach max drawdown through many small daily losses that accumulate over time.
