One big day, then the account fell apart?

It is a common pattern: a big win, a bigger size, then the giveback. The free check-up shows it in your own history and the rule that stops it. Free for the first 15 traders.

FTMO, The5ers, FundedNext, FundingPips: when a daily or max loss rule changes, we update the tools and tell you.

How the rule is calculated

Most firms divide your best day by your total profit: with a 40% rule, a best day of 2,000 needs at least 5,000 of total profit (2,000 ÷ 0.40). Some older rules, like FTMO's legacy Best Day Rule, divide by the sum of your positive days only, so losing days do not raise the bar. If tomorrow is a new best day, the requirement grows with it: that is why the calculator shows the most you can make in one day and stay within.

What counts as my best day?

The day with the highest closed profit, measured from your prop's daily reset. Open trades do not count until they are closed.

What happens if I break it?

It depends on the firm. At FTMO (1-Step) and in FundedNext Futures challenges it is not a breach: you keep trading until the ratio falls. At FundingPips the reward waits until the rule is met. Check your firm's page for your account.

How do I fix a ratio that is too high?

Only by making more profit on other days, without a new bigger day. The calculator shows how much more you need and the most you can make in one day without making the problem worse.
