Consistency rule
A consistency rule is a prop firm requirement that no single trading day or trade may account for more than a set percentage of total profit, preventing a trader from passing an evaluation on one outsized win.
A common form caps any single day at 30–50% of total profit. The purpose is to filter out traders who reached the target through one lucky, oversized position rather than a repeatable process — from the firm's perspective, a trader who passed on variance is a liability once funded.
It catches people out because it can be breached while profitable and while every loss limit is respected. A trader can hit the target, break no risk rule, and still fail because the profit arrived too unevenly.
Read the consistency rule before the first trade, not after the target is reached. It is the rule most often discovered at the point it is broken.
