Drawdown decoded: static vs trailing (EOD vs intraday)
Your drawdown is the single most important number in your whole account: the most you’re allowed to lose before the account is dead. Everyone knows that part. The reason this one lesson saves more accounts than anything else in the course is that the firms measure it in ways most traders never stop to understand — and the gap between what you think your limit is and where it actually sits is exactly where evals go to die.
There are two families. Get which one you’re in clear before you place a single order.
Static drawdown — the easy one
A static drawdown is a fixed floor. Buy a $50,000 account with a $2,000 limit and the line sits at $48,000. It does not move. Balance at $48,001, you’re alive; $47,999, you’re out. That’s the whole rule. It’s the friendliest type to trade because the number in your head matches the number in the firm’s system — no surprises.
Trailing drawdown — the one that ends challenges
A trailing drawdown follows your highest balance up, then locks underneath you. This is the rule that fails more traders than bad trades ever will, so let’s walk it one step at a time:
- You start at $50,000 with a $2,000 trailing limit → line at $48,000.
- You trade up to $51,000. The line trails up with you to $49,000.
- You trade up to a peak of $52,000. The line is now at $50,000 — above your original starting balance.
- You give back ~$2,001 from that peak, landing near $49,999. The account is blown — even though you’re still up roughly $0 on paper and never came within $2,000 of the $48,000 you had in your head.
That’s the trap in one picture: you can be green on the account and still breach, because the limit climbed to a level you weren’t watching.
Two flavors of trailing — and firms aren’t always loud about which
“Trailing” itself comes in two versions with very different risk profiles:
| Drawdown type | How the limit moves | How forgiving | Watch for |
|---|---|---|---|
| Static | Never moves | Most forgiving | Almost nothing — it’s fixed |
| End-of-day (EOD) trailing | Recalculates off your closed balance at session end | Middle | Intraday spikes don’t lock against you, but a higher close ratchets the floor up overnight |
| Intraday trailing | Follows your live equity, unrealized profit included, tick by tick | Least forgiving | A big unrealized run-up you hand back can lock the floor right under you in real time |
A strategy that’s perfectly safe on EOD-trailing can quietly blow an intraday-trailing account doing the exact same thing. Same word on the website; completely different machine underneath.
Worked example — You’re up $1,800 unrealized at midday on an intraday-trailing account, then give it all back before the close. The floor may have already trailed up to meet that $1,800 peak — so you can finish the day flat and still be far closer to (or through) your limit than you realize. On an EOD-trailing account, that same round-trip never happened in the firm’s eyes, because only the close counts. Identical trading, opposite outcome — decided entirely by which flavor you’re on.
The good news most people miss: where it locks
On a lot of firms the trailing line stops trailing once it reaches your starting balance (sometimes start plus a small buffer). After that it behaves like a static floor at break-even. So the scary moving target becomes a fixed, plannable number the moment you know where your firm locks it. That single fact is worth more than any indicator — it tells you exactly how much real room you have.
Key takeaway — Before your next eval, you must be able to answer three questions. If you can’t, you don’t understand your own risk yet, so don’t place the trade:
- Is the drawdown static or trailing?
- If trailing — EOD or intraday?
- Where does it lock (and does it lock at all)?
I keep the static-vs-trailing answer for every firm I’ve tested in the firm notes — it’s the first thing I check before I ever fund an account, ahead of the profit split, the price, or the discount code.
