What the rule measures
A consistency rule limits how dependent your result is on one outsized day. The usual formula divides your best single day by your total profit for the period. If the ratio is above the firm's limit, the payout is held until you have traded more.
A worked example
With a 40% rule and $3,000 of total profit, your best day can be at most $1,200. If your best day was $1,500, you need total profit of at least $3,750 before the ratio drops back under 40%, so you need another $750.
Evaluation vs funded
Some firms apply a consistency rule only in the evaluation, some only on funded accounts, and some on both, sometimes with different percentages. Our account data lists both values where firms publish them.
- Check the rule for both phases.
- Run your numbers in the Consistency calculator.
- Plan position sizing so no day dominates.
This guide is general education, not financial advice. Rules differ between firms and change over time; always read the firm’s current terms.
