The explainer
Intraday vs end-of-day trailing drawdown
The trailing drawdown is the rule that ends most prop accounts, and most traders only really understand it after it has cost them one. Here is what it actually does, and why the intraday version is stricter than people expect.
What a trailing drawdown actually is
It is a loss limit that moves. It sits a fixed distance below the highest point your account has reached, and it follows you up as you make new highs — but it never comes back down.
The important consequence: a trailing drawdown does not punish losing. It punishes giving back. You can lose steadily and survive a surprisingly long time. Make a big gain and hand it back, and you can fail while still showing a profit for the day.
How an account fails while up on the day
Take a $100,000 account with a $3,000 trailing drawdown. The floor starts at $97,000.
- You run the balance up to$104,000
- The floor ratchets to$101,000
- You give back down to$100,500
- Up $500 on the account — and failedbelow the floor
Nothing about that is a losing streak. It is one good run followed by a give-back, which is the single most common way funded accounts die.
Which one your account uses changes everything
| Model | What moves the floor | What it means for you |
|---|---|---|
| Intraday trailing | Your highest equity during the session, including unrealised profit on an open trade. | Stricter. A trade that goes $1,500 green and round-trips to flat still moves your floor up $1,500, permanently. Bank profit rather than admiring it. |
| End-of-day trailing | Your realised balance, checked once at the daily close. | Kinder in one specific way: a winner that round-trips does not permanently raise your floor. It does not stop you breaching intraday. Most firms still enforce the floor in real time against open losses. |
The part that costs accounts
End-of-day says when the floor moves, not when it can be hit
“End-of-day” sounds like the session is a free zone. It is not. On most firms the limit updates at the close but is enforced every second, against your net liquidation value — balance plus open profit and loss. In their own words:
“Your drawdown limit only UPDATES at the end of each trading day, but it is ENFORCED continuously throughout the day. If your net liquidation value touches the limit at any moment, your account fails immediately.”
So an open position can take you through the floor at 10:15 and the account is gone, even if you would have closed green. What end-of-day actually buys you is narrower and still worth having: a winner that goes $2,000 up and round-trips has not permanently raised your floor the way it would on an intraday account.
Of the firms in our rule book, at least three end-of-day programmes state this real-time enforcement explicitly. Check your own — it is the difference between a bad day and a dead account.
Firms differ, and they change their rules. Apex-style accounts have historically used intraday trailing while Topstep has used end-of-day, but account types vary even within one firm. Confirm which model your specific account uses before you rely on any of this — it changes how you should manage an open winner.
The number you should actually watch
Prop marketing trains you to think in account sizes — a “$100,000 account.” But the money that decides whether you survive is the drawdown allowance, not the headline number.
On that $100,000 account with a $3,000 trailing drawdown, a $1,000 stop is not “1% risk.” It is a third of everything standing between you and a blown account. Three of those in a row and you are finished, on an account that sounded like it had six figures behind it.
So the number worth putting in front of you on every trade is: what percentage of my remaining failure buffer am I risking here?
- What is a trailing drawdown?
- A moving loss limit that sits a fixed distance below the highest point your account has reached. As your balance makes new highs the limit follows it up, but it never moves back down. Touch it and the account is done.
- What is the difference between intraday and end-of-day trailing drawdown?
- Intraday trailing follows your highest equity during the session, including unrealised profit on an open trade, so a winner that round-trips still ratchets your floor up permanently. End-of-day trailing only moves the floor once, at the close, on your realised balance. But that is a difference in when the floor MOVES, not in when it can be BREACHED: most firms with end-of-day trailing still enforce the floor continuously, against your net liquidation value including open losses. You can fail an end-of-day account in the middle of the session and never see the close.
- Does the trailing drawdown stop moving?
- On most firms it locks once you have banked enough profit, commonly around the starting balance plus a small buffer. After that the floor stays put. The exact lock point varies by firm and by account type, so confirm it with your own firm.
- Why does a $1,000 loss matter more than 1% on a $100,000 account?
- Because the advertised account size is not the money at risk. If that account carries a $3,000 trailing drawdown, a $1,000 loss consumes about a third of the entire buffer keeping the account alive. The buffer is the number that matters, not the headline size.
