# What is Consistency rule?

> A consistency rule is a prop firm rule that limits how much of a trader's total profit can come from a single day or trade, to stop one outlier result from passing or paying out.

In a prop firm, the consistency rule exists to stop one lucky day from passing an evaluation or triggering a payout. It is usually written as a percentage: no single day may account for more than a set share of total profit. If it does, the trader keeps trading until the share falls, rather than failing outright, at most firms.

Firms apply consistency rules to the evaluation, the funded stage, or both, and some apply them only to payout requests. Futures firms and instant funding programs use them most often, because those products have fewer other filters.

Alternatives that serve a similar purpose include minimum trading days, payout caps and a minimum number of profitable days before a payout.

## Why it matters

Consistency rules protect your payout ratio from outlier days, but they are also one of the rules traders feel most cheated by when they discover them late. Weigh the protection against the cost in goodwill and reviews, and if you keep one, show it beside the price with a worked example rather than three clicks deep in the terms.

## Example

With a 40% consistency rule and $5,000 total profit, no single day may contribute more than $2,000. A trader with a $2,500 best day needs total profit of at least $6,250. Illustrative only.
