More prop accounts are lost to drawdown rules than to anything else. Two programs can both advertise a 10% maximum loss and still give you very different room to trade, depending on how that 10% is measured. This guide explains every common drawdown rule, shows how each one plays out on a $100,000 account and gives you a short checklist of questions to ask before you buy.
Key takeaways
- Most programs have two limits: a daily loss limit and an overall maximum loss. Breaching either usually ends the account.
- Equity-based limits count open, floating losses. Balance-based limits only count closed trades.
- A static maximum loss never moves. A trailing maximum loss follows your peak, so profits can shrink your room.
- End-of-day trailing updates once per day, which is more forgiving than trailing on every price tick.
- Always find out when the daily limit resets and which balance it is calculated from.
The two limits on almost every account
Nearly every evaluation and funded account has two separate loss limits:
- Daily loss limit. The most you can lose in one trading day. A common figure is around 3% to 5% of the account.
- Maximum loss limit, also called overall or max drawdown. The lowest level your account can ever reach. A common figure is around 6% to 12%, depending on the program.
These figures are typical industry ranges, not the rules of any particular firm. What matters as much as the percentage is how each limit is calculated. The rest of this guide covers the variations you will meet. If you are still choosing a format, read our guide to challenge types first, because one-step and instant programs often use the stricter variants.
How daily loss limits are calculated
Firms calculate daily limits in a few different ways. On a $100,000 account with a 5% daily limit, the differences look like this:
- Fixed from the initial balance. The limit is always 5% of $100,000, or $5,000, regardless of how the account has performed.
- From the start-of-day balance. If you start the day at $104,000, the limit is measured from $104,000. The dollar amount may be $5,000 or 5% of $104,000, depending on the firm.
- From the higher of start-of-day balance or equity. If you carry an open trade worth $2,000 in profit into the new day, your start-of-day equity of $106,000 can become the reference point. Losing that open profit then counts against today's limit.
The reset time matters too. Daily limits usually reset at a fixed server time, often around the New York close, rather than at midnight in your time zone. A loss taken just before the reset and one taken just after belong to different days.
Balance-based versus equity-based limits
Balance is the value of your account counting only closed trades. Equity is balance plus or minus the profit or loss of open trades.
- Balance-based limits only check closed results. An open trade can float deep into loss without a breach, as long as you close it above the limit.
- Equity-based limits check your live equity continuously. A brief spike against an open position can end the account, even if the trade closes in profit.
Most firms use equity for at least one of the two limits. If your strategy uses wide stops, scales into positions or holds through volatile periods, an equity-based limit effectively reduces the room you have. Plan your stop losses so that the worst-case combined loss of all open trades stays inside the limit.
Static maximum loss
A static maximum loss is fixed from the starting balance and never moves. On a $100,000 account with a 10% static limit, the floor is $90,000 for the life of the account.
If you grow the account to $108,000, your room to the floor becomes $18,000. Profits build a cushion. That makes static drawdown the most forgiving variant, and it is common on two-step programs. You can browse firms that use the format in our 2-step prop firms list, then confirm the drawdown type for the specific program.
Trailing maximum loss
A trailing maximum loss follows your highest balance or equity upwards and never moves down. The gap between your peak and the floor stays the same, so profits do not build a cushion in the same way.
Many trailing rules stop trailing once the floor reaches the starting balance. In the example above, if equity reached $110,000, the floor would lock at $100,000 and stay there. Check whether and where the trail stops, because it changes the long-term risk of the account considerably.
Trailing drawdown is particularly common in futures programs. Our guide to futures vs forex prop firms explains why.
End-of-day trailing drawdown
End-of-day (EOD) trailing updates the floor only once per day, using the closing balance or equity, instead of trailing every intraday peak.
EOD trailing is friendlier to traders who let winners run and give some open profit back. It is still stricter than a static limit, because a good day permanently raises the floor.
How to stay inside the limits
- Set a personal daily stop below the firm's limit. If the firm allows 5%, stop yourself at 2% to 3% so one bad trade cannot end the account.
- Size every trade from the distance to your floor, not from the account size. On a trailing account, that distance shrinks after every new peak.
- Count open trades together. On equity-based rules, the combined worst-case loss of all open positions must stay inside the limit.
- Know the reset time and avoid holding trades across it without understanding how it affects your limit.
- Use a calculator. Our risk calculator shows how many consecutive losses your plan can survive.

Frequently asked questions
What is the difference between daily drawdown and max drawdown?
Daily drawdown limits how much you can lose in one trading day and resets each day. Maximum drawdown limits how far the account can ever fall and does not reset.
Is trailing drawdown worse than static?
For most traders, yes. A trailing limit follows your peak, so giving back open or closed profit can breach the account even when it is above its starting balance.
Do floating losses count toward the daily limit?
On equity-based rules they do. On balance-based rules only closed trades count. Check which applies to each limit on your program.
When does the daily loss limit reset?
Usually at a fixed server time set by the firm, often around the end of the New York trading session. Check the firm's stated reset time and time zone.
Can I get my account back after a breach?
Usually not. Some firms sell a discounted reset or retry, but a breach normally ends that account.
