Prop Firm Drawdown Rules Explained: Daily Loss vs Max Loss

If you only master one thing about prop firm challenges, make it this. More evaluations are failed on a misunderstood drawdown rule than on bad trades. Let's make it crystal clear, with numbers.

There are two different limits — and both can end you

Almost every prop firm enforces two separate loss limits at the same time:

• Maximum daily loss — how much you can lose in a single trading day (commonly ~5%).
• Maximum overall loss / total drawdown — how far your account can fall from the start, ever (commonly ~10%).

Breaching either one fails the account instantly. They're measured differently, so you have to watch both.

Daily loss, with a real example

The daily limit is usually measured from your balance (or equity) at the start of the trading day, and it resets each day.

$100,000 account, 5% daily limit. You start the day at $100,000 → your floor for today is $95,000. If equity touches $95,000, you're out — even if the account was up overall.

Key trap: it often tracks equity, not just closed balance. A deep floating loss on an open position can breach the limit before you ever close the trade. Watching only your closed P/L is how people get caught.

Maximum overall loss, with a real example

The overall limit is measured from your initial balance. On a static model it's a fixed floor for the whole challenge.

$100,000 account, 10% max loss → hard floor at $90,000. Touch it at any point and the account fails, no matter how well you were doing last week.

Static vs trailing

Some firms use a trailing maximum drawdown that follows your highest balance/equity up (until you reach a certain profit), instead of a fixed floor. That means as you make money, the "kill line" rises too. Read your firm's exact definition — static and trailing behave very differently when you're in profit.

Why people breach by accident

• They watch closed balance and ignore floating (equity) drawdown.
• They forget the daily floor resets — and treat a fresh day's small buffer like the full overall limit.
• They size too big, so one normal losing streak eats the daily limit in an hour.
• They hold through high-impact news and a spike blows past the floor.

The simple defense: build a buffer

Professionals don't trade up to the limit — they stop well before it. If the daily cap is 5%, set your personal stop at 3–4%. If overall is 10%, treat 8% as your real wall. That margin turns "account failed" into "bad day, try again tomorrow." It's the same principle we apply throughout the FTMO step-by-step guide.

Quick reference

• Daily loss: measured from start of day, resets daily, often on equity. Buffer it.
• Overall loss: measured from initial balance, never resets (static) or trails up (trailing). Buffer it more.
• Both apply at once. Stay clear of both, every day.
