What is a max daily loss limit?

A max daily loss limit caps how much your account equity can drop within a single trading day, usually measured from your balance at the start of that day. Most prop firms set this at 5% — if your equity drops by more than that in one day, you fail the challenge immediately, regardless of your overall profit or loss.

What's the difference between static and trailing drawdown?

A static drawdown limit is calculated from your initial account balance and never changes. A trailing drawdown limit is calculated from the highest balance (or equity) your account has ever reached, meaning the floor moves up as you make profit — but never moves back down. Trailing drawdown is generally stricter once you're in profit.

What happens if I breach the daily loss or overall drawdown limit?

Breaching either limit — even intraday, even if your account recovers before the day ends on some firms — typically results in an automatic, instant failure of the challenge or funded account. There is usually no warning or grace period, which is why monitoring these limits in real time is critical.

How can I avoid breaching my prop firm's drawdown rules?

Calculate your maximum allowable loss per trade based on your remaining daily and overall drawdown allowance, not just your account size. Many traders also stop trading for the day once they've used 50% of their daily loss limit, giving themselves a buffer against slippage, spread widening, or an unexpected losing streak.

How to use the prop firm drawdown calculator

Prop firm challenges live or die on two numbers: your max daily loss and your max overall drawdown. Enter your account size, current equity, and the balance you started today with, along with your firm's daily and overall drawdown percentages, and this calculator instantly tells you exactly how much room you have left before either limit is breached.

If your account uses a trailing drawdown (where the breach level rises along with your highest-ever balance), switch the drawdown type to "Trailing" and enter the highest balance your account has reached. For static drawdown accounts, the breach level is fixed relative to your starting account size.

The status badges — Safe, Caution, Danger, and Breached — give you an at-a-glance read on your risk exposure. Many traders check this before placing every new trade, especially after a losing streak, to make sure a single bad trade can't end their evaluation.
