Understanding the consistency rule
What it limits
Most prop firms cap how much of your total profit can come from a single day — commonly 20% to 40%. It stops "one lucky trade" accounts.
The formula
best day / total profit x 100. If that's over the limit, you fail. To pass, total profit must be at least best day / limit%.
How to pass
Trade steadily. Spread profit across more days, avoid oversized single-day wins, and keep growing your total until your best day drops below the limit.
Consistency rule questions
What is the consistency rule in prop firm trading?
The consistency rule limits how much of your total profit can come from a single trading day. If your best day makes up more than the firm's allowed percentage (often 20-40%) of your total profit, the account can fail the consistency check at payout.
How is the consistency rule calculated?
Divide your highest single-day profit by your total profit, then multiply by 100. If that percentage is above the firm's limit, you break the rule. To pass, your total profit must be at least your best day divided by the allowed percentage.
How do I pass a 20% consistency rule?
With a 20% limit, no single day can be more than 20% of your total. That means your total profit needs to be at least 5x your biggest day. Trade steadily and spread profit across multiple days.
Does every prop firm have a consistency rule?
No. Some firms have no consistency rule, others apply it only at payout, and the exact percentage varies. Always read your firm's rules — this tool is a general estimate to help you plan.
