Consistency rule
A prop-firm rule capping how much of your profit one day may contribute, forcing steady performance.
A prop-firm rule capping how much of your profit one day may contribute, forcing steady performance.
Firms that want to see a repeatable edge rather than one lucky candle limit the share of total profit any single trading day may represent - commonly 30% or 40% during evaluation. Exceed the cap and you must keep trading until the denominator grows: the win is real, but the target does not count until the rest of the account catches up. Some firms apply the same idea to a single position or to trading during high-impact news.
The rule changes tactics more than strategy. Hit the cap early and the rational move is to trade smaller - or stop entirely - until enough other days accumulate, because adding risk to dilute your own best day can just as easily breach the loss limit. Read when the rule applies (evaluation only, or funded too), what it is measured against (net profit, or closed trades), and whether it resets monthly or at payout.
Worked example
A $50,000 evaluation with a 30% consistency cap and a $3,000 target means no day may contribute more than $900. A single $1,500 day forces at least $3,500 more profit across other days before the target is even eligible to count.
