Every prop firm account has two drawdown rules that can end it independently: a daily drawdown (the most you can lose in one day, usually 4 to 5 percent) and a max drawdown (the most you can lose in total, usually 8 to 12 percent). Breach either and the account is gone. Most traders who fail do so on the daily limit, and almost always for behavioural reasons rather than a broken strategy. This guide explains every variant so you know exactly where your lines are.
Daily drawdown
The daily drawdown, or daily loss limit, caps how much you can lose in a single trading day. Most firms set it at 4 to 5 percent of your starting balance. Hit it and you lose the account or, at best, the day. It resets at the firm's daily boundary.
It can be balance-based (measured from your balance at the start of the day) or equity-based (including floating losses on open trades). Equity-based is stricter, because a deep unrealised loss can breach you before you close. The specific FTMO version is broken down in FTMO daily loss limit rules.
Max drawdown
The max drawdown is the overall floor your account cannot fall below across the life of the challenge, typically 8 to 12 percent from the starting balance. On a $100,000 account with a 10 percent max drawdown, $90,000 is the line. It is the slower of the two kill switches but just as final.
Static vs trailing
A static max drawdown floor is fixed at the start and never moves. A trailing floor follows your highest balance or equity upward, locking in profit and shrinking your remaining room as you grow. The classic mistake is measuring against your starting number after the floor has already trailed up behind your gains. The dedicated breakdown is in static vs trailing drawdown explained.
The two are separate kill switches
| Rule | Measures | Typical size | Resets |
|---|---|---|---|
| Daily drawdown | Loss in one day | 4 to 5% | Each trading day |
| Max drawdown | Total loss from start or peak | 8 to 12% | Never (life of account) |
You can pass the max drawdown comfortably and still fail on a single bad day's daily drawdown. That is exactly how most challenges end.
Why the daily rule is the one that gets you
The numbers are not the hard part. The hard part is the moment after a loss, when the urge to win it back immediately drives one more trade, then another, into the daily drawdown. The failure is behavioural, and the full picture is in why traders fail prop firm challenges. Knowing the rule does not protect you if you cannot stop in that window.
That is the case for enforcing the daily limit rather than relying on discipline. EmotionLock reads your real MT5 trades through a read-only investor passwordconnection and blocks trading apps once you hit a daily limit you set well inside the firm's line, so the bad day stops before it becomes a breach.
Frequently asked questions
What is the difference between daily drawdown and max drawdown?
Daily drawdown is the most you can lose in a single trading day, usually 4 to 5 percent. Max drawdown is the most you can lose in total from your starting balance over the life of the account, usually 8 to 12 percent. They are separate kill switches: breaching either one ends the account, independently of the other.
What is trailing drawdown?
A trailing drawdown floor follows your highest achieved balance or equity. As your account grows, the floor rises with it, locking in your gains and reducing your remaining loss allowance. A static drawdown floor, by contrast, is fixed from the start and never moves. Many traders breach because they forget the trailing floor has moved up.
Is drawdown calculated on balance or equity?
It depends on the firm. Balance-based drawdown uses your closed balance, so floating losses on open trades do not count until you close. Equity-based drawdown includes floating profit and loss, so a deep but unrealised drawdown on an open position can breach you. Equity-based rules are stricter. Always check which your firm uses.
Why do most traders fail prop firm challenges on drawdown?
Most failures are behavioural, not strategic. A trader has a normal losing trade, tries to win it back immediately, and overtrades into the daily drawdown. The rule that catches them is the daily loss limit, and the cause is the post-loss emotional state, not a flawed strategy. That is why enforcement of the daily limit matters more than knowing the rules.
The summary
Prop firm drawdown comes in two forms: a daily limit and a total max, either of which ends the account, and the max can be static or trailing, balance or equity based. Know your exact lines, but remember that most failures are the daily limit breached in a tilted moment. Enforcing that daily stop is what tools like EmotionLock are for.
