How the Consistency Check Works
The rule caps how much any single day can contribute to your total profit. Multiply your total profit by the limit to get the most one day may earn. Your best day passes when it stays at or under that cap. If it is over, you either keep trading to grow your total, or work out the minimum total that would bring the day back inside the limit.

Frequently Asked Questions
It is a prop firm rule that caps how much any single trading day can contribute to your total profit. It stops one outsized day from carrying the whole evaluation, pushing you to show steady results across many days rather than a single lucky session.
The firm sets a percentage, often 20% to 40%, and applies it to your total profit. Multiply the two and you get the most any one day is allowed to earn. Lower percentages demand more days of trading before you qualify.
Yes. If a single day's profit is more than the allowed share of your total, the consistency rule is breached even when you are otherwise profitable. The fix is to keep trading so your total grows, which shrinks that day's share back under the limit.
It depends on the firm. Some apply consistency only during the evaluation, while others keep it on funded accounts or tie it to payouts. Always read your firm's rulebook, since the percentage and whether it applies post-funding vary between programs.
