A consistency rule caps how much of your total profit may come from a single day. It exists so a firm does not pay out on one lucky trade, and it catches traders at the worst possible moment: the target is reached, the account looks passed, and the payout is refused because one day was too good.
The trap is that the rule is checked against the profit at the time of the payout, not on the day the profit was made. A large day early on is not a breach yet — it becomes legal as the total grows. This shows exactly how much more total profit is needed to bring your best day back inside the rule.
When to use it
- After an unusually good day, before deciding whether to keep trading.
- When the profit target is reached but the payout has not been requested.
- When planning position sizes, to avoid a day that traps the account.
- Before choosing a firm, to see how restrictive its rule really is.
The rule compares the best day against the total, so raising the total is the only way to fix a breach.
Share = Best Day ÷ Total Profit
Largest Allowed Day = Total Profit × Rule %
Total Needed = Best Day ÷ Rule %
Headroom Tomorrow = (Total + Tomorrow) × Rule % ≥ Best Day- The percentages vary by firm and by plan: thirty percent is common, twenty percent is stricter, and some firms have no rule at all. Take the number from your own account, not from a general article.
- Some firms apply the rule to losing days as well, and some measure it against the target rather than the profit made. Read which one applies before relying on this.
- A breach usually delays a payout rather than failing the account. The account keeps trading, and the profit has to grow until the best day fits.
- Trading smaller to fix a consistency problem works. Trading larger to reach the target faster makes it worse, because the new large day replaces the old one as your best.
An account $8,000 in profit with a best day of $3,600, under a 30% consistency rule.
Working: $3,600 of $8,000 is 45%, well over the 30% cap. For that day to be legal the total has to reach $12,000, which means $4,000 more profit spread across other days. Reaching the profit target is not enough on its own.
Does breaking the consistency rule fail my account?
At most firms it does not fail the account; it blocks the payout until the profit distribution improves. Some firms handle it differently, so check the rules that came with your account rather than assuming.
Can I fix it by trading bigger?
No, and it is the usual mistake. A bigger day becomes the new best day, which raises the total required. The way out is more profit spread over more days, which means smaller positions, not larger ones.
Is the rule measured against profit or against the target?
Both exist. Measured against profit is more common and is what this calculator uses. If your firm measures against the target, enter the target in the profit field to see that version.
Do losing days count?
At most firms the rule looks only at the best winning day against net profit, which is what this does. A few firms cap the worst day as well; that is a separate rule and is usually described alongside the daily loss limit.
