Daily Loss vs Max Drawdown: Static and Trailing Drawdown Explained
The two rules that fail most prop firm accounts, explained with worked examples: how daily loss limits reset, how static and trailing drawdown are calculated, and how to stay safe.
If you ask funded traders what ended their failed challenges, the answer is almost always the same: the daily loss limit or the maximum drawdown. Profit targets can be reached slowly, but these two rules end an account the moment they are broken. Understanding exactly how they are calculated is the single most useful thing you can do before trading a challenge.
What is the max daily loss?
The maximum daily loss is the most your account is allowed to fall within one trading day. It is usually a percentage of the starting balance or of the balance at the start of the day, and it resets every day at a set time.
Example
On a $100,000 account with a 5% daily loss limit, you can lose up to $5,000 in a day. If you start the day at $102,000, many firms calculate the limit from that day's starting balance, so your floor for the day is $97,000. Check whether your firm counts open (floating) losses as well as closed trades: most do.
The key point is that floating losses on open trades usually count. A trade that dips $5,200 against you before recovering can fail the account even if it closes in profit.
What is the max drawdown?
The maximum drawdown is the furthest your account can fall overall, across all days. It comes in two main flavours, and the difference matters a lot.
Static drawdown
The floor is fixed. On a $100,000 account with a 10% static drawdown, the account fails if equity ever falls below $90,000. If you grow the account to $108,000, the floor stays at $90,000, which gives you more and more room as you profit.
Trailing drawdown
The floor moves up as your account reaches new highs. With a 6% trailing drawdown on a $100,000 account, the floor starts at $94,000. If your account peaks at $104,000, the floor trails up to $98,000. It does not move back down when you lose.
| Account high | Static 10% floor | Trailing 6% floor |
|---|---|---|
| $100,000 (start) | $90,000 | $94,000 |
| $103,000 | $90,000 | $97,000 |
| $106,000 | $90,000 | $100,000 |
| Falls back to $101,000 | $90,000 | $100,000 (only $1,000 of room left) |
Some firms stop trailing once the floor reaches the starting balance, which is sometimes called a lock. Others trail on closed balance only, and some trail on equity including open trades. These details change how much room you really have, so always read how your program defines it.
How to stay safe under both rules
- Write the dollar floors down before you trade: today's daily-loss floor and the current max-drawdown floor.
- Set a personal daily stop at about half of the firm's daily limit.
- Always use a stop loss, and size positions so a full stop costs no more than 0.5% to 1% of the account.
- Avoid holding several correlated trades at once; together they can breach the daily limit in one move.
- On a trailing account, bank profits gradually. Big spikes in equity drag the floor up quickly.
- Be careful around high-impact news, when spreads widen and price can gap through your stop.
How BlackProp shows it
Each BlackProp challenge lists its daily loss and drawdown type on the challenge page before you buy, and your dashboard shows your balance, equity and high-water mark in real time, so you always know how close you are to each limit.
Frequently asked questions
Does floating loss count towards the daily loss limit?+
At most prop firms, yes. Open losses count as well as closed trades, so an open trade can breach the limit before you close it.
Is trailing drawdown bad?+
Not necessarily, but it gives you less room after a strong run. It rewards steady growth and penalises big equity swings.
When does the daily loss limit reset?+
Usually once per day at a fixed server time. Check your program's rules for the exact reset time.
