Worked example

A $100,000 account with a 5% daily limit (5% of the initial balance, measured from today’s starting balance) and a 10% static max loss. Today started at $102,000 and equity is now $99,500. Today’s floor is 102,000 − 5,000 = $97,000, so you have $2,500 of room left today. The overall floor is $90,000, so $9,500 of room remains overall. The suggested EA guard is $98,000, the floor plus 20% of the $5,000 daily limit, which leaves a cushion for slippage.

Static or trailing?

A static max loss never moves: on a $100,000 account with a 10% limit, the floor stays at $90,000. A trailing max loss follows your highest balance or equity upward, so profits raise the floor; some firms stop trailing once it reaches the starting balance.

Prop firm drawdown FAQ

It depends on the firm. Most set the daily limit as a percentage of the initial balance and measure it from the day’s starting balance or equity; some use whichever is higher. Check your firm’s rules page for the exact wording.

At most firms, yes. The limit applies to equity, so floating losses count before you close the trade.

At the firm’s server midnight, which is often not your local midnight. The rules page states the time zone.

An EA with an equity guard can close trades before the floor. Set it with a cushion for slippage and price gaps, and remember a gap over the weekend can jump past any guard.
