Two accounts, same starting balance, same “10% max drawdown” on the label — and one of them can breach you while you’re up on the day. The difference is whether that drawdown is static or trailing, and misreading which one you have is how traders lose accounts they thought were safe.
Two floors, two very different meanings
A drawdown limit is a floor your account balance or equity can never fall below. Cross it and the account is done, no matter how the rest of the day went. Both types define a floor — they just decide where the floor sits using completely different logic.
- Static drawdown measures from a fixed point: your starting balance. The floor never moves.
- Trailing drawdown measures from a moving point: your highest equity or balance reached. The floor rises as you make money.
Everything that trips traders up flows from that one distinction. The trailing drawdown explainer goes deep on the mechanics; here’s the practical version.
How a trailing floor chases your equity up
With a trailing drawdown, the floor follows your high-water mark. Make money and the floor ratchets up behind you; it does not come back down when you give some profit back. That’s the trap: your loss allowance is measured from your peak, not from where you are now.
Play it out. You start a session up nicely, your equity prints a new high, and the trailing floor snaps up to match. Then a normal pullback takes back part of that profit — and because the floor has already moved up, that ordinary retrace can breach you while you are still green on the account overall. You didn’t have a bad day; you had a good day followed by a normal one, and the geometry of a trailing floor turned it into a breach.
Two details decide how vicious a trailing floor is, and they vary by firm:
- Equity vs balance trailing — a floor that trails your equity moves on unrealized profit too, so an open winner you let run drags the floor up before you’ve banked anything.
- When it stops trailing — many programs freeze the trailing floor once it reaches your starting balance (often after you’ve made a set amount), converting it to static from then on. Confirm this point with your firm; it changes the whole risk picture.
How a static floor just sits there
A static drawdown is the simpler animal. The floor is pinned to your starting balance and never moves, up or down. If your account starts at 100k with a 10k static drawdown, the floor is 90k on day one and it’s 90k after you’ve made 8k — you can give back that 8k and still not breach, because the floor never chased you up.
That makes static drawdown far more forgiving of a give-back after a good run. Your profit genuinely becomes cushion. The cost is that a static floor gives you no rising protection — it won’t lock in your gains — but for surviving normal volatility, sitting still is a feature.
Which is harder to survive
There’s no universal answer — it depends on how you trade.
| Static drawdown | Trailing drawdown | |
|---|---|---|
| Floor measured from | Starting balance | Highest equity/balance reached |
| Moves up as you profit | No | Yes |
| Comes back down after a give-back | n/a — never moved | No |
| Can breach while green on the account | No | Yes |
| Punishes a give-back after a peak | No | Yes |
| Kinder to | Traders who bank then retrace | Steady grinders who rarely give back |
Read the table by your own style. If you scalp small and steady and rarely hand profit back, a trailing floor barely touches you. If you have volatile sessions — big up, big give-back — a trailing floor is a minefield and a static one is a gift. Know which you are before you pick a program.
Find your exact floor before every session
Whichever type you have, the discipline is the same: know the precise number your equity can’t touch today, before you place the first trade. For a static floor that number is constant. For a trailing floor it moves, so you recompute it from your current high-water mark each session. The prop-firm drawdown calculator does the math either way, so “how much room do I have” is never a guess mid-trade.
This is also where an enforced limit earns its place. A trailing floor that moves intraday is exactly the kind of number a human loses track of in a fast market — which is why the durable protection is a hard limit set at the broker, a margin inside the firm’s line, that closes you out before a rising floor catches you. Shibiki tracks the moving floor and holds that line for you, so a good-day-then-normal-day can’t quietly turn into a breach.
Confirm the type with your firm — programs differ
Do not assume. The same firm often runs static and trailing programs side by side, evaluation and funded stages can use different types, and a trailing floor may or may not freeze once it hits your starting balance. Two firms’ “trailing drawdown” can behave differently in the details that matter. Read your specific program’s rulebook and, when in doubt, ask support in writing. Different programs draw the floor differently — see how it plays out at FTMO and Apex Trader Funding, then confirm your own account’s exact terms before you trade it.
