Consistency Rule Explained
Last verified: 2026-05-25 PDT
A consistency rule is a firm-specific rule designed to stop one oversized day from carrying the whole evaluation or payout window.
There is no universal regulator definition of “consistency rule” for funded-trader evaluations. That matters. Firms can use different formulas, thresholds, and consequences. Some rules affect passing. Some affect payout. Some raise the target. Some simply require more trading days.
The common thread is simple: the firm wants to see whether performance is distributed or concentrated.
Quick definition
A consistency rule limits how much of total profit can come from one trading day, or requires profit to be spread across multiple qualifying days. The exact formula depends on the firm.
Example math
If a firm has a 50% consistency rule and a trader makes $3,000 total profit, the largest single day may need to be $1,500 or less.
If one day is $2,000 and total profit is $3,000, then the best day is 66.7% of total profit. The trader may need to keep trading until total profit grows enough that the best day falls under the threshold.
Why firms use consistency rules
Traders hate consistency rules because they feel like moving goalposts.
But from the firm’s point of view, one oversized day does not prove repeatability. A trader can catch one clean NY open move, oversize, hit the target, and still have no process.
The rule is designed to separate a process from a lucky spike.
Evaluation consistency vs payout consistency
Some firms apply consistency during the evaluation. Others apply it during payout cycles. Some use both. Some have no eval consistency but require funded payout consistency.
That distinction matters. A trader can pass an evaluation and still struggle to withdraw if the funded-stage consistency rule is tighter.
Common mistakes
- ▸Trying to pass in one huge day.
- ▸Increasing size near the target.
- ▸Forgetting best-day percentage after a big win.
- ▸Thinking exceeding consistency always fails the account.
- ▸Not knowing whether the rule resets after payout.
- ▸Treating minimum trading days and consistency as the same thing.
How to apply it
Before trading, write down:
- ▸consistency percentage;
- ▸whether it applies to eval, funded, payout, or all three;
- ▸formula used by the firm;
- ▸whether exceeding it fails the account or just requires more trading;
- ▸whether it resets after payout;
- ▸your maximum acceptable daily profit before you stop pressing.
Bucko view
The consistency rule is not the enemy. Oversizing is the enemy. The rule just makes oversizing visible.
If one day is doing all the work, the strategy may not be as stable as the trader thinks.
Bottom line
Consistency rules punish hero days. If your plan depends on one oversized trade to pass, the rule is doing exactly what it was built to do.
