Trailing drawdown explained: static, EOD and intraday
- Your maximum drawdown is a balance floor. Touch it and the account is usually closed.
- A static floor never moves. A trailing floor rises as your account makes new highs, either at the end of each day or in real time.
- Intraday (real-time) trailing counts open profit, so giving back an unrealized gain can permanently shrink your room.
- Most trailing floors stop rising at some point, often at or just above the starting balance. After that the floor is effectively static.
- The exact rules vary by firm and change over time. Your firm's current published rules always govern.
If you have ever blown a prop account on a day you were up money, there is a good chance a trailing drawdown was involved. It is the rule that causes the most confusion, because the number you read on the sign-up page (say, "$2,000 max drawdown") is not a fixed amount of room. It is a distance from a moving line.
This guide walks through the three common types, shows how the floor moves with real numbers, and covers the details that tend to surprise people: where the floor stops, why funded accounts sometimes show a $0 balance, and what a payout does to your cushion.
The floor, not the number
Think of the drawdown as a floor under your account balance. If your balance (or equity, depending on the firm) reaches that floor, the account fails. The advertised drawdown amount tells you where the floor starts. The type of drawdown tells you how it moves after that.
All the examples below use a hypothetical $50,000 account with a $2,000 drawdown, so the floor starts at $48,000.
Static drawdown
A static floor stays where it started. On a $50,000 account with $2,000 of static drawdown, the floor is $48,000 on day one and $48,000 on day forty, no matter how much you make.
This is the simplest version. Every dollar of profit you bank adds a dollar of room. If you grow the account to $53,000, you have $5,000 between you and the floor.
End-of-day (EOD) trailing drawdown
With EOD trailing, the floor is recalculated once per trading day, after the session closes. The firm looks at your closing balance, and if it is a new high, the floor moves up to sit $2,000 below it. If the day closed lower, the floor stays put. It never moves down.
What happens during the day does not move the floor. A trade that is up $1,500 at lunch and closes flat has no effect on it.
Hypothetical $50,000 account, $2,000 EOD trailing drawdown, floor stops trailing at the $50,000 starting balance.
| Day | Day P&L | Closing balance | Highest close | Floor |
|---|---|---|---|---|
| Start | - | $50,000 | $50,000 | $48,000 |
| 1 | +$600 | $50,600 | $50,600 | $48,600 |
| 2 | -$400 | $50,200 | $50,600 | $48,600 |
| 3 | +$900 | $51,100 | $51,100 | $49,100 |
| 4 | +$1,100 | $52,200 | $52,200 | $50,000 (locked) |
| 5 | -$700 | $51,500 | $52,200 | $50,000 |
On day 4 the math says the floor should be $50,200, but it stops at the $50,000 lock level. From that point on it behaves like a static floor.
One detail matters here: in many EOD setups the floor is only recalculated at the close, but your account can still breach it at any moment during the day. If your balance plus open losses dips below today's floor at 10:15 am, that usually counts. Check how your firm measures a breach.
Intraday (real-time) trailing drawdown
Intraday trailing tracks the highest value your account reaches at any moment, including open profit on trades you have not closed yet. Every new peak in equity pulls the floor up, in real time.
This is the version that punishes giving back open profit. The floor rises with your unrealized gains, then stays there if the trade comes back.
Same $50,000 account, but with $2,000 intraday trailing. Floor starts at $48,000.
- You enter a trade. It runs to +$1,200 open profit, so equity peaks at $51,200. The floor moves to $49,200.
- The trade reverses and you close it at +$200. Your balance is $50,200.
- The floor stays at $49,200. Your room is now $1,000.
Under EOD trailing, the same trade would have closed the day at $50,200 and moved the floor to $48,200, leaving $2,000 of room. Same trade, same result, half the cushion.
That is why traders on intraday trailing accounts pay close attention to how they manage winners. A trade that goes well and then round-trips is not neutral. It costs you drawdown room even though it made money.
Why the difference is bigger than it looks
On an intraday trailing account, your usable room is really the drawdown amount minus whatever open profit you have given back since your last equity peak. A trader whose trades often run +$800 before settling at +$200 is quietly losing $600 of room on each one, until the floor locks. Your journal can show this if you record the maximum favorable excursion (the best open profit) on each trade next to the final result.
Where the floor stops: the lock
Most trailing floors do not trail forever. At some point the floor stops rising and becomes fixed. Common lock levels are:
- The starting balance. On a $50,000 account the floor stops at $50,000, so it locks once your high reaches $52,000.
- The starting balance plus a small amount, for example $100. The floor stops at $50,100, which takes a high of $52,100.
For example, several firms lock the floor at or just above the starting balance, but the exact level and the trigger differ. Once the floor locks, every additional dollar of profit adds a dollar of room, the same as a static account.
The practical point: until the lock, your room is capped at the drawdown amount. After the lock, it can grow. Reaching the lock is often the first real milestone on a funded account.
Funded accounts that start at $0
Some firms display a funded account balance starting from $0 instead of $50,000. The mechanics are identical, only the labels change.
A funded account shown as $0 with $2,000 trailing drawdown has a floor at -$2,000. If the floor locks at the equivalent of the starting balance plus $100, it stops at +$100, which happens once your high reaches +$2,100. Translate everything back to "distance from the floor" and it reads the same as the $50,000 version.
How payouts can move or lock the floor
Withdrawing money lowers your balance. What it does to the floor depends on the firm, and this is where people get caught out.
- The floor stays where it was. Your balance drops by the payout, the floor does not, so your cushion shrinks by the full amount you withdrew.
- The floor locks at a set level after a payout, for example at the starting balance. If it was still trailing below that, your cushion can shrink further.
- Payout limits are tied to your cushion, for example you can only withdraw profit above a buffer, so the account keeps some room after the payout.
Your balance is $52,500 and the floor is locked at $50,000, so you have $2,500 of room. You withdraw $1,500. Your balance falls to $51,000 and the floor stays at $50,000. You now have $1,000 of room, which may be less than a normal losing day for you.
Before requesting a payout, work out what your cushion will be afterward, not just what you will receive. The payouts guide covers the rest of the requirements.
How the drawdown interacts with other rules
The trailing floor is rarely the only limit. Many accounts also have a daily loss limit, and on any given day your real room is whichever is closer: the floor or today's daily limit. Some funded accounts also have consistency rules that affect when you can withdraw.
Checking your own numbers
To know where you stand, you need three things: the drawdown type, the lock level, and your high-water mark (highest close for EOD, highest equity for intraday). From those, floor = high-water mark minus drawdown, capped at the lock level.
- The trailing drawdown calculator lets you plug in your numbers and see where the floor sits.
- The prop firm rules pages list each firm's drawdown type, amount and lock level, with sources and the date they were last checked.
- If you journal in TradeHarbor, the prop account presets apply each firm's drawdown rules to your imported trades, so the account status shows your current floor and remaining room.
Whatever tool you use, treat it as a check, not the final word. Firms update their rules, and the firm's current published rules and your account dashboard always govern.
