Trailing drawdown moves your breach floor on every tick. End-of-day drawdown moves it once. Worked examples, the five questions to ask any prop firm, and how to size positions under each.
Most funded accounts don't die because the trader was wrong about the market. They die because the trader was wrong about where the breach floor was sitting.
Two firms can both advertise "10% maximum drawdown" and give you completely different amounts of room to work with. The number in the headline is the least important part of the rule. What matters is what the floor is measured *from*, and how often it moves.
Your floor is set once, at the start, and stays there.
On a $50,000 account with a 10% maximum drawdown, the floor sits at $45,000 permanently. If you grow the account to $70,000, the floor is still $45,000. You have $25,000 of room.
Static is the most forgiving model and the least common on cheap challenges, for the obvious reason: it transfers risk to the firm as your account grows.
Your floor trails your account's highest closing balance, and only updates at one fixed moment each day.
Same $50,000 account, 10% allowance. If you close Monday at $52,000, your floor moves from $45,000 to $47,000 and stays there for the whole of Tuesday, no matter what happens intraday. Close Tuesday at $51,000 — lower than Monday — and the floor doesn't move at all. It tracks the *high-water mark* of daily closes, not the most recent close.
EOD is the middle ground, and for discretionary intraday traders it's usually the most workable trailing model.
Your floor trails your account's highest equity point in real time, recalculated on every price update.
This is where accounts quietly bleed out. On most firms using this model, the high-water mark includes floating profit — profit on positions you haven't closed yet. Your trade runs $3,000 in your favour, you don't take it, price reverses, you exit flat. Your P&L for the day is zero. Your floor just moved up $3,000 and it is not coming back down.
Day 1 — You start at $50,000. A position runs to $52,000 in floating profit, you give some back, and you close the day at $50,800.
Day 2 — A position runs to $53,500 in floating profit, reverses hard, and you close the day at $50,200.
After two days you are up $200. Here's where each model has left your floor:
Static Drawdown:
EOD Trailing Drawdown:
Intraday Trailing Drawdown:
Three traders, identical trades, identical results. The intraday trader starts Day 3 with a third of the room the static trader has — and has done nothing wrong. They simply let two winners run and didn't close them at the high.
Note also what happened on Day 2 under EOD: the floor didn't move, because Tuesday's close was lower than Monday's. Under intraday trailing it moved another $1,500 on a losing day, because the floating high was higher.
Two firms can both say "trailing drawdown" and mean materially different things.
Trailing on closed balance. The floor only moves when you actually bank a profit. Floating gains are invisible to the calculation. Letting a winner run costs you nothing; closing it raises your floor by the amount you closed.
Trailing on peak equity. The floor moves the instant your unrealised P&L makes a new high. You are penalised for the profit you *touched*, whether or not you kept it.
The gap between these two is enormous for anyone who scales out, uses runners, or holds through a retracement. On a balance-trailed account, a trade that goes +$4,000 and comes back to flat is a non-event. On an equity-trailed account, it just cost you $4,000 of permanent room.
If a firm's rules page doesn't state which applies, that is itself a finding. Ask support in writing and keep the reply.
"End of day" is not a universal moment.
Futures-focused firms typically reset at the US futures close, 5:00 pm ET. Forex-focused firms usually reset at midnight server time, and server time is frequently GMT+2 or GMT+3 — which shifts by an hour when European daylight saving changes, without any announcement.
Two consequences worth internalising:
1. A position held across the reset is scored twice: it affects the close that sets tomorrow's floor, and it's still open when tomorrow starts.
2. If you assume the reset is at your local midnight and it's actually four hours earlier, every daily-loss calculation you make is wrong.
Find the exact reset time and timezone before your first trade, not after your first breach.
On many firms — particularly in futures — the trailing floor climbs only until it reaches your starting balance plus a small buffer, then locks permanently.
On a $50,000 account, the floor might trail up to $50,100 and freeze there. Once you've grown the account past roughly $55,100, you can never breach by dropping back to your starting balance; the worst case is a small loss. That is a very different account to trade than one where the floor trails forever.
Firms that never stop trailing leave you permanently exposed to giving back a run. You can be at $58,000 on a $50,000 account — clearly profitable — and breach on a bad week because your peak was $63,000.
Ask: does the trail freeze, and at what level?
Here's the interaction that catches funded traders who have already done everything right.
You've grown a $50,000 account to $58,000 under a trailing model. Your floor sits at $53,000. You request a $5,000 payout. Balance drops to $53,000.
Your floor did not drop with it.
This is the question to ask before you request your first payout: does a withdrawal lower my drawdown floor?
Prop Firm Payout Rules Explained
Under static: size against your fixed floor. The calculation is the same on day one and day ninety. Your risk per trade can stay constant as a percentage of the remaining buffer.
Under EOD trailing: recalculate your available room every morning, after the reset, using your closing balance from yesterday. Treat that number — not your account balance — as your working capital for the day. If yesterday closed at a new high, you have less room today than you did yesterday, even though you made money.
Under intraday trailing: you have to account for room you might consume during the trade itself. Practical adjustments:
- Cut your per-trade risk meaningfully below what the headline drawdown suggests. Many experienced traders on these accounts run 0.25–0.5% per trade against an advertised 10% buffer.
- Be deliberate about runners. On equity-trailed accounts, an unclosed position at a new high is spending your buffer in real time.
- Take partials earlier than you otherwise would. It doesn't help the equity-trailed calculation directly, but it reduces the size of the give-back.
- Track your peak equity yourself, daily. Don't rely on the dashboard to show it — many don't display the current floor at all.
Common Reasons Traders Fail Prop Firm Evaluations
Copy these into a support ticket. Keep the written answers.
1. Is the maximum drawdown static, EOD trailing, or intraday trailing? And does it change between the evaluation phase and the funded account? Many firms switch models at funding — usually to the trader's disadvantage.
2. Does the floor trail on closed balance or on peak equity?
3. What is the exact daily reset time, and in which timezone?
4. Does the trailing stop at any point? If yes, at what level?
5. Does requesting a payout lower the drawdown floor?
A firm that answers all five clearly and in writing is telling you something useful about how it operates. A firm that deflects is telling you something useful too.
There isn't a universally correct answer, but there is a fit question.
Static suits swing traders, anyone holding overnight, and anyone whose edge involves large winners with deep retracements. It's also the only model where scaling the account meaningfully increases your safety.
EOD trailing suits intraday traders who flatten before the close. You get full freedom inside the session and a predictable floor for the next one. For most day traders this is the best available compromise.
Intraday trailing suits high-frequency, tight-stop, in-and-out strategies where you rarely hold a large floating profit. If your style involves letting trades breathe, this model is structurally hostile to it — no amount of discipline changes the arithmetic.
The cheapest challenge on the market is usually cheap because it uses the most punitive drawdown model. That's not a scam; it's pricing. Just make sure you know which one you're buying.
Compare firms and their drawdown models
Trailing drawdown recalculates your breach floor continuously as your account makes new highs, often including unrealised profit on open positions. End-of-day drawdown recalculates the floor once per day, using your balance at the daily close, so intraday swings don't move it.
For most trading styles, yes. Under intraday trailing, floating profit you never bank can still permanently reduce your available room. End-of-day trailing only responds to your closing balance, which gives you full freedom inside the session.
Yes. If your floor trails your peak and never freezes, an account that ran to $63,000 and fell back to $57,000 can breach even though it started at $50,000. This is the most common surprise on trailing accounts.
It depends on the firm. On many, a withdrawal reduces your balance without reducing your floor, which consumes your buffer directly. Confirm the policy in writing before your first payout request.
There's no standard. Futures firms commonly reset at 5:00 pm ET; forex firms typically use midnight server time, often GMT+2 or GMT+3. Server time is not your local time, and it can shift with daylight saving.
On some firms it locks once it reaches your starting balance plus a small buffer, after which you can't breach back below your original balance. On others it trails indefinitely. This is a firm-by-firm rule and one of the most important to check.
