You clear the profit target, the balance is green and, when you request the payout, the dashboard stops you: your best day weighs too much against your total profit. Here is how the consistency rule is computed, how much you need to earn before that day stops blocking you, and how to watch the ratio every session without doing the math by hand.
What the consistency rule is
The consistency rule limits how much your best day may weigh against what you have earned: the profit of your best day divided by total profit must not exceed the percentage the prop firm sets. If it does, the payout request is blocked (or, at some firms, the evaluation is not considered passed) until the ratio is back within the limit.
Firms use it because they want repeatable results, not one lucky strike. A trader who makes $3,000 over twenty sessions of $100 to $250 has demonstrated a process. Another who makes the same $3,000 with one $2,800 day and nineteen flat days has demonstrated, above all, that one day he bet big. To the firm, the second profile is the one that breaks the account as soon as the market turns, and paying it out with that history is a risk it prefers not to take.
Each firm sets the percentage, which phase it applies to (evaluation, funded account or only at payout time) and whether it measures gross or net of commissions. None of that is standard and all of it changes over time: read it in your account rules, not in a video from six months ago.
The formula with an example
Ratio = best day ÷ total profit. The ratio has to sit at your firm's percentage or below. The same math yields the number that really matters: minimum total profit = best day ÷ percentage.
Suppose your best day is $1,200 and your accumulated profit on the account is $3,000. The ratio is 1,200 ÷ 3,000 = 40%. If your firm applied a 30% rule (an illustrative percentage), you would be blocked. To unblock you need a total of 1,200 ÷ 0.30 = $4,000: $1,000 more in profit, with no new day exceeding $1,200. At $4,000 the ratio sits exactly at 30%; from there, every dollar you add improves it.
- Write down every session's result with the same criterion your firm uses (gross or net).
- Take the largest of all the days in the period that counts: since the account opened or since the last payout, depending on the firm.
- Divide by the sum of all days, losses included.
- Compare with the percentage. If you are over, compute the minimum total and note how much is missing.
Note step 3: the denominator is the current total profit, not the profit target. If you lose money, the total shrinks and the ratio rises. A negative week can block you again even without a new big day.
How much profit you need: a table
The table applies the minimum-total formula to three big-day sizes and three percentages. The percentages are illustrative: every firm sets its own, some change it by account phase and all can modify it. Figures rounded up to the dollar.
| Best day | 30% rule | 40% rule | 50% rule |
|---|---|---|---|
| $500 | $1,667 | $1,250 | $1,000 |
| $1,000 | $3,334 | $2,500 | $2,000 |
| $2,000 | $6,667 | $5,000 | $4,000 |
Read it horizontally: under a 30% rule, a $2,000 day forces you to accumulate $6,667 before you can get paid; under a 50% rule the same day only requires $4,000. And vertically: under the same rule, doubling the best day doubles the profit you need.
It is also useful to flip it: the maximum day you can afford = total profit × percentage. With $3,000 accumulated and a 30% rule, any day above $900 blocks you. That number, computed before the session opens, is the most practical reference the rule gives you.
The big-day paradox
Before the big day you had $1,800 of profit with a $500 best day: a 27.8% ratio, inside a 30% rule. A trend session comes, everything works and you close at +$1,200. Now you have $3,000, more money than ever in the account, and you are further from the payout: 40%. To get back to 30% you need $4,000, that is, $1,000 more, when the week before this rule, at least, was no longer holding you back.
The way out is boring on purpose: keep trading at your normal size. If your average is $150 net per traded session, that is about seven days. Do not stop trading, because the ratio does not improve on its own; and do not raise size to shorten the path. A double-size day of +$1,500 lifts the total to $4,500 but turns $1,500 into your new best day: 33.3%, still blocked, and the bar has moved to $5,000.
What is in your hands: keeping the size your risk plan dictates, accepting that the payout slips one or two weeks and, above all, not losing. A −$400 day lowers the total to $2,600 and raises the ratio to 46%.
Daily limit and scaling plans
With the daily loss limit below and the consistency rule above, the firm defines a band of acceptable daily results. With a $1,000 daily limit and a 30% rule, both illustrative, and $3,000 accumulated, your session should move between −$1,000 and +$900. It is a narrow band, and it explains why prop accounts reward the trader with similar days and punish the streaky one.
Not every firm imposes a daily limit (Apex and Lucid Flex have none according to their published rules; check yours), but the trailing drawdown plays a similar role from below. And the big day does not gift you cushion either: while the drawdown trails your balance, the room below does not grow in proportion to what you have made.
Scaling plans push in the same direction. When the firm opens more contracts to you as the cushion grows, the temptation is to use them the first day you can, which usually coincides with a favorable streak: exactly the big day the rule penalizes. A ladder-style risk plan, with risk per trade rising in steps, tends to produce days of similar size, which is what the rule rewards. Raising size when the plan says so, and not before, keeps the ratio under control without giving up growth.
How to track it every day
The ratio depends on two numbers that change every session, so it has to be looked at every day, not the morning you plan to request the payout. The minimum is a trading journal with a daily P&L calendar: at a glance you see your best day, sum the period and know whether you are under the percentage. If you trade several accounts, the ratio belongs to each one: the 100K's big day does not affect the 50K, and one account can be blocked while the other gets paid.
- Before the session: compute your maximum day (total × percentage) and keep it in sight. It is the number at which to raise the stop or stop trading.
- After the session: log the day's net with the firm's criterion and recompute the ratio. It takes less than a minute.
- On Fridays: review the whole week. Losing days lower the total and can block you again without any new big day warning you.
Common mistakes
- Chasing the ratio with more size. It raises the total, yes, but any good day at that size becomes the new best day and moves the bar. And the extra size brings you closer to the daily limit and the drawdown.
- Counting gross when the firm counts net, or the reverse. With 30 trades a day in micros the difference is not small: a $1,100 gross day can be $1,000 net, and that changes both the ratio and the total. Check which figure your firm uses and use the same one in your journal.
- Forgetting the losing days. They shrink the denominator. A $4,000 total with a $1,200 best day (30%) goes to 33.3% after a single −$400 day.
- Stopping "so as not to spoil it". The ratio does not fall by waiting; it only falls by adding profit. Stopping makes sense if you are going to trade badly, not as a ratio strategy.
- Mixing accounts. If you copy trades into several accounts, each has its own ratio, and different commissions or fills mean the best day is not identical in all of them.
- Not knowing which phase or which day cut-off applies. Evaluation, funded or payout window; since the account opened or since the last payout; and the day by the futures session, not by your local midnight. Every combination gives a different ratio.
Frequently asked questions
Is the consistency rule computed on gross or net profit?
It depends on the firm: some measure net of commissions and others gross, and it can change with the account phase. Check your account rules and log your days in the journal with the same criterion, because a $1,100 gross day that is $1,000 net gives different ratios.
What happens if I have a big day right before requesting a payout?
You do not lose the money: the request is delayed until total profit dilutes that day. The minimum total is the best day divided by the firm's percentage; with a $1,200 day and a 30% rule that is $4,000. Keep trading at your normal size until you get there.
Do losing days affect the consistency rule?
Yes. Total profit is the denominator, so every losing day shrinks it and raises the ratio. With a $4,000 total and a $1,200 best day you sit at 30%; one −$400 day leaves you at $3,600 and 33.3%, blocked again even without a new big day.
Next step
Start by seeing your days the way the firm sees them: sync your account in Jornalo (the Free plan covers one account and the last 31 days, no card) and look at the P&L calendar. If your problem is the other extreme, the trailing drawdown calculator tells you how much cushion you have left without signing up. And to make days come out at a similar size, build a ladder-style risk plan.
