Prop Firm Consistency Rule Calculator: 30% Single-Day Profit Cap
The 30% Consistency Rule dictates that no single trading day can generate more than 30% of your total accrued profit. If your total profit is $10,000, your best trading day cannot exceed $3,000. If one day yielded $5,000, you must continue trading until total profits reach at least $16,667 ($5,000 / 0.30) to qualify for payout approval.
Prop firm consistency rules prevent "lot size gambling" where a trader passes an evaluation through a single lucky news trade. Firms examine both daily profit distribution and lot size standard deviation before approving withdrawal invoices.

Lot Sizing Consistency Range (0.5x - 2.0x)
Firms like FundedNext and The5ers also audit lot size variance. If your average trade is 2.0 lots, executing trades below 0.5 lots or above 4.0 lots triggers automated compliance flags for lot manipulation.

FREQUENTLY ASKED QUESTIONS & EXPERT CLARIFICATIONS
Does breaching the consistency rule fail the prop account?
No, it does not fail the account; instead, your payout request is delayed until subsequent trading brings your single-day profit percentage below the firm threshold.
