Consistency rule
calculator
Many prop firms cap how much of your profit can come from one day. Paste your daily results and see where you stand.
Most firms measure it as best day ÷ total profit. Some count only profitable days or use a different window, so check your firm's exact wording.

- Best day

- More profit needed (without a bigger day)
- $265.00
What the consistency rule is
A consistency rule limits your best day to a share of your total profit, for example 30%. If you made $1,000 in total and your best day was $410, that day is 41% of your profit and breaks a 30% rule.
How to fix a breach
Keep trading normally until your total profit is large enough: the calculator shows how much more you need. Avoid a single big day; it moves the target further away.
