The Consistency Rule Explained (With the Actual Math)
Last updated
A consistency rule caps how much a single trading day's profit can contribute to your total. If your best day exceeds the cap (commonly set between 20% and 50%), you can't pass the evaluation or request a payout until the rest of your trading catches up. The firm's goal is to filter out traders whose results come from one lucky oversized bet rather than a repeatable process.
How the calculation works
The formula is simple but regularly misunderstood:
- Take your best single day's profit.
- Divide it by your total profit over the period.
- If that percentage exceeds the firm's limit, you fail the consistency check.
Example with a 30% rule. Apex Trader Funding applies a 30% consistency rule at payout: when you request a payout, no single trading day can account for more than 30% of your total profit balance. Say you made $900 on one strong day and $100 across the rest of the period. Your best day is 90% of your $1,000 total, far over the cap. You don't lose the account; you need more profitable days before the payout is approved.
How much more do you need?
The useful question is: how much additional profit brings your best day under the limit? Solve for the total that makes your best day exactly the cap:
- Required total = best day ÷ (limit ÷ 100)
- Additional profit needed = required total − current total
In the example above: $900 ÷ 0.30 = $3,000 required total, so you need $2,000 more profit (spread across other days) before that $900 day satisfies a 30% rule. This surprises people: one outlier day can lock a payout behind weeks of additional trading. Our consistency calculator does this math for any daily profit series and limit.
Where the rule applies
Firms attach consistency rules at different points, and the difference matters:
- During the evaluation: an inconsistent profit distribution means you don't pass the phase, even if you hit the profit target.
- At payout: you keep the funded account, but withdrawal requests are delayed until the distribution evens out. This is the more common placement, and it's how Apex's 30% rule works.
- Not at all: a meaningful minority of firms (over 30 verified firms as of 2026, including FTMO, FundedNext, FundingPips and The5ers) apply no consistency rule to payouts.
Some firms also pair consistency with related restrictions, like Apex's 5:1 risk-to-reward rule (your stop loss can't exceed five times your profit target on any trade). Always read the specific firm's rulebook; "consistency rule" is not standardized across the industry.
Who should care
If you trade a steady intraday strategy with similar size every session, a consistency rule will rarely touch you. It bites two groups hard:
- News and event traders, whose profits arrive in concentrated bursts on a few days per month.
- Part-time traders, who trade a handful of sessions and can't dilute a big day quickly.
If that's you, filter for firms without the rule; the payout terms elsewhere (split, frequency, minimums) are often comparable, so you're not necessarily trading away anything to get the flexibility.
The bottom line
A consistency rule doesn't cap how much you can make; it shapes how your profit must be distributed before the firm treats it as real. Before buying an evaluation, check three things: the percentage, whether it applies at evaluation or payout, and what happens when you breach it (delay vs. failure). All three are listed in the rules section of every firm profile in our directory, along with each firm's rule-change history.
