How to pass a prop firm challenge: the rules that matter

A prop firm challenge (also called an evaluation or combine) is a test account run by a proprietary trading firm. You pay a fee, trade a simulated account under a set of rules, and if you hit the profit target without breaking a rule, the firm offers you a funded account. Most people who fail do not fail because their analysis was wrong. They fail because they misunderstood a rule: usually the drawdown. This guide explains the rules that decide most challenges, with real examples quoted from the firms' own help pages, so you know exactly what you are signing up for.

How a challenge works

Almost every futures prop challenge has the same shape:

1. A starting balance, such as $50,000. This is simulated money. Topstep, for example, describes its Trading Combine as "a simulated account with one rule and two objectives".
2. A profit target you must reach, such as $3,000 on a $50,000 account.
3. A maximum loss you must never breach, usually called the drawdown or maximum loss limit.
4. Extra conditions: a daily loss limit, a consistency rule, a minimum number of trading days, position-size caps, and time rules such as being flat before the daily close.

Pass, and you move to a funded stage, which has its own rules, including the conditions for requesting a payout (a withdrawal of profit). Many funded accounts are also simulated, and payouts come from the firm under its own terms.

The three types of drawdown

The drawdown is the lowest your account balance is allowed to go. Firms often call that lowest level the floor, threshold or minimum balance. Touch it and the account fails. What matters is how that floor moves.

Static drawdown

The floor is fixed at the start and never moves. On a $50,000 account with a $2,000 static drawdown, the floor is $48,000 forever. It is the easiest to understand, and it never punishes you for being in profit. It is less common in futures challenges today than the two trailing types.

End-of-day (EOD) trailing drawdown

The floor follows your highest end-of-day balance and only moves up. It is recalculated once, after the session closes. Topstep's Maximum Loss Limit works this way: it "is calculated from your account balance high at the end of the trading day", so "the minimum account balance will not be adjusted while you are trading". Their own example: make $500 on day one of a $50K account and the floor rises from $48,000 to $48,500, and it stays there even if you lose $500 the next day.

One trap: the floor only moves at the end of the day, but most firms enforce it in real time. Tradeify's rules page says its EOD limit "is still enforced in real time, and touching it fails the account immediately". MyFundedFutures says open-equity losses count too. A trade that dips below the floor mid-session fails the account even if it would have recovered by the close.

Intraday trailing drawdown

The floor follows your highest balance at any moment, including unrealised profit on open trades. Apex Trader Funding's help centre spells it out: the peak balance "includes both realized and unrealized gains", the threshold "never moves down", and "no closing trade is required" for it to rise. Their $50,000 example: an open trade that pushes the balance to $50,900 lifts the floor from $48,000 to $48,900 immediately. If that trade then closes at $50,300, the floor stays at $48,900.

That is the rule that surprises beginners most: a winning trade you let come back to breakeven has permanently cost you room.

When trailing stops

Most trailing drawdowns stop trailing at some point, after which the floor is fixed. The lock level differs by firm, as of September 2026:

• Topstep: once the Maximum Loss Limit reaches the starting balance, "it won't change for the remainder of the account".
• MyFundedFutures and Lucid (LucidFlex): the EOD trail locks at the starting balance plus $100 (for example $50,100 on a $50K account).
• Apex: in funded (Performance) accounts, trailing stops at starting balance plus $100. In evaluations it depends on the platform: on Rithmic and Wealthcharts it stops at the profit-target balance, and on Tradovate it "continues to trail indefinitely".

Same trades, three rules

The chart below runs one set of hypothetical trades on a $50,000 account with a $2,000 maximum loss through all three drawdown types. Switch between them and watch the red floor.

Static. The floor sits at $48,000 the whole time. The lowest point, $49,300 on day 4, is $1,300 clear of it.

End-of-day trailing. Day 1 closes at $50,600, so the floor rises to $48,600 overnight. Day 2's intraday high of $51,400 does not count because it did not hold to the close. The account survives.

Intraday trailing. The open-profit peaks of $50,900 and $51,400 drag the floor up to $49,400. The day-4 dip to $49,300 touches it: the account fails, even though it is still down only $700 from where it started.

Daily loss limits

A daily loss limit (DLL) caps how much you can lose in one trading day. Two things vary a lot between firms: whether there is one at all, and what happens when you hit it. As of September 2026:

• Topstep: the DLL is optional in the Trading Combine and Express Funded Account and automatic in the Live Funded Account. Hitting it "is not a rule violation": positions are flattened and you cannot trade until the next session.
• Blue Guardian Futures (Standard): 2% of the initial balance (no daily limit on the $25,000 account). A breach is "a soft breach, not a hard breach", and the account is reinstated the next trading day.
• Tradeify: depends on the plan. Select evaluations have no daily loss limit; Growth evaluations do, set by account size.
• Apex: its evaluation rules page states there is no daily maximum drawdown.

Also check when the "day" starts. Futures firms usually run the trading day from the evening open, not midnight: Topstep's runs from 5 PM to 3:10 PM Central Time, Tradeify's from 6 PM to 5 PM Eastern. A trade placed on Monday evening belongs to Tuesday's session.

Consistency rules

A consistency rule limits how much of your total profit can come from your single best day. The idea is to stop one lucky, oversized day from passing an account. The maths is the same everywhere:

Best day profit ÷ total profit = consistency percentage

If the result is above the firm's limit, you have not met the rule yet. The limits, as of September 2026:

Two details catch people. First, losing days reduce total profit but do not reduce your best day, so a loss can push you further from the target. Apex's own example: make $1,000 on day one and lose $200 on day two, and your ratio is $1,000 ÷ $800 = 125%. Second, at Topstep you cannot fix a best-day problem by trading more the same day; any extra profit that day just raises the best day.

The fix is always the same: more profit, made on other days, each smaller than your best day. You can work out how much with:

Best day ÷ limit − total profit = extra profit needed

Payout rules

Passing the challenge is not the finish line. Funded accounts have their own conditions before you can request a payout. As of September 2026, examples include:

• Topstep Express Funded: two paths. Standard needs 5 winning days of $150 or more; Consistency needs 3 trading days and the 40% consistency target. Either way you can request up to 50% of the account balance, subject to a cap by account size, with a 90/10 profit split.
• Tradeify: Growth needs 5 profitable trading days per payout cycle; Select Flex needs 5 winning days; Lightning has no minimum days. Tradeify's funded accounts also require that over 50% of trades and profits come from trades held longer than 10 seconds.
• Apex: the 50% consistency check above is applied at the payout request, and it resets after each approved payout.

Read the payout page before you buy an evaluation, not after you pass. Profit split, minimum days, caps and consistency all decide how much of a funded balance you can actually withdraw, and when.

A pre-trade checklist

1. Write down your drawdown type, amount, and when (if ever) it stops trailing.
2. Write down your daily loss limit, if any, and whether hitting it fails the account or pauses it.
3. Know your firm's trading day and the time you must be flat.
4. Calculate your consistency limit in dollars for your best day before you start the day.
5. Decide your own per-trade risk as a small, fixed slice of the distance to your floor, not of the account balance.
6. On intraday trailing accounts, decide in advance how much open profit you will let come back before you manage the trade.

Common mistakes

• Measuring risk from the account size. On a $50,000 account with a $2,000 drawdown, your real capital is $2,000. Size positions against that.
• Letting winners round-trip on an intraday trail. Open profit that disappears still raised your floor.
• Assuming the EOD floor is only checked at the close. It moves at the close; it is usually enforced all day.
• One huge day. It feels like progress, then the consistency rule makes you earn it again on other days.
• Trusting a summary instead of the firm's page. Rules differ by firm, plan and platform, and they change. Summaries, including this one, go out of date.
