"Consistency rule" is one of the most misunderstood terms in prop trading. It does not mean trading every day, and it does not mean avoiding large wins — it means no single trading day may account for more than a set share of total profit.

The Core Idea

If a firm sets a 20% consistency requirement and a trader's best day produced 40% of their total profit, the payout is capped so that the best day represents no more than the 20% threshold, with the remainder scaled down accordingly.

Why Firms Use It

The rule exists to filter out traders whose results come from one lucky trade rather than a repeatable process. A trader who grinds out small, steady gains passes the rule automatically; a trader whose entire result rests on one large win does not.

Common Misreadings

• It is not a daily loss limit — those are separate rules with their own thresholds.
• It usually applies only at payout time, not during the evaluation phase, though some firms apply it to both.
• Failing the consistency check does not fail the account; it typically reduces the payout amount for that cycle.

Prop Firm Match Perspective

Read the exact percentage and the exact stage (evaluation, funded, or both) a firm applies its consistency rule to before assuming two firms' rules are equivalent — the same label covers meaningfully different mechanics across firms.
