What the rule says
The consistency rule exists so that one lucky day cannot carry an account to its target. The most common form: your best single day must be no more than a set percentage of your total profit, often somewhere between 30% and 50%. Some firms measure against the profit target instead, or apply it at each payout. Find out which one yours uses before you plan around it.
A worked example
Four days: $1,800, $400, $500 and $300. Total profit $3,000, best day $1,800. That is 60% of the profit. Against a 40% rule the account is over the limit.
The number is a reminder that profit made after the big day does not erase it: it only dilutes it. The bigger the best day is, the more profit the rest of the account has to produce.
Planning around it
- Know your ceiling. If a 40% rule applies and your target is $3,000, a single day above $1,200 puts you over the limit unless the other days make up the difference.
- Beware the outsized day. One trade that is much bigger than your usual result is what usually breaks the rule. Decide your size before the trade, not after a winning streak.
- Check it as you go. Do not wait until the target is reached to find out that the best day is too large.
