A daily loss limit is the most you may lose in a single trading day before the firm closes your account - commonly 4-5% of the starting balance. Unlike maximum drawdown, it resets: a new trading day restores the full allowance.

Measurement detail matters. Firms differ on whether the limit is calculated from the starting balance or from the day's starting equity (which includes overnight gains), and on whether open floating losses count. Both choices change the effective cushion, so read the definition, not just the percentage.

Worked example: a 5% daily limit on $100,000 is $5,000. Hit it through one trade or ten - the platform does not care - and the account closes immediately. Two days at -$4,900 each never breach the daily limit but together may breach a 10% maximum drawdown, which is why the daily number alone is never a complete risk plan.

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.
