Key points
- A consistency rule caps how much of your total profit may come from a single day.
- Where it applies matters as much as the percentage: evaluation, payout, or both.
- It is arithmetic on your best day against your total, so it can be satisfied by trading more, not less.
- A firm that publishes the percentage but not where it applies has not told you when it bites.
What the rule says
A consistency rule states that no single trading day may account for more than a stated share of the total profit. A 50% rule on $6,000 of total profit means the best day may not exceed $3,000.
It exists to distinguish a repeatable process from a single fortunate session. A firm funding an account wants evidence that the result can happen again; one day producing almost all of the profit is not that evidence.
Where it is tested
The same percentage produces very different products depending on when it is applied, and this is the part firms are least consistent about publishing.
| Applied at | What it controls | What it feels like |
|---|---|---|
| Evaluation | Whether a stage counts as passed | A pass can be withheld until the profit is better distributed |
| Payout | Whether a withdrawal is approved | The account is funded and in profit, and the money still waits |
| Both | Passing and withdrawing | The rule is a permanent feature of the account |
The payout case surprises people most. Nothing has gone wrong; the account passed, it is profitable, and the withdrawal is simply not eligible yet because the distribution has not caught up. Rex records where the rule applies as part of the value and shows "scope not published" where a firm states the percentage alone — which, in the current record, is the common case.
A worked example
A funded account with a 50% consistency rule at payout. Over three weeks the trader books $2,000, $700, $500, $2,900 and $400, for a total of $6,500.
- Best day: $2,900. Half of the total is $3,250, so the rule is satisfied — just.
- If the $2,900 day had been $3,600, the total would be $7,200 and half of it $3,600. Still satisfied, exactly at the line.
- If the $2,900 day had been $4,500 with the others unchanged, the total is $8,100 and half is $4,050. The best day exceeds it, and the payout waits.
Note what the third case implies: a better day made the payout harder. That is not a flaw in your trading; it is the rule doing exactly what it says. The remedy is more profitable days, not smaller ones.
Trading inside the rule
The rule is arithmetic, so it can be planned around without changing a strategy's edge.
- Know your target total before you start. On a 50% rule, your best day must stay under half of it; on a 30% rule, under a third.
- If an unusually good day happens early, expect to need several more days before the distribution allows a pass or a payout.
- Scaling down after a strong day does not help the ratio; it slows the growth of the denominator.
- Check whether the rule counts realised profit per calendar day or per trading session. Firms differ, and a session that spans midnight can be counted either way.
Consistency in the record
Consistency rules are common across the futures firms in the snapshot and appear on several Forex instant and one-step plans. A 50% best-day cap is the most frequently published figure.
Almost every firm publishes the percentage without publishing where it applies, so most consistency values in Rex read "50% best day · scope not published". Open a challenge page and click the value to see the source, or read the rule definition.
Common questions
Does a consistency rule apply to losses as well?
Generally no. It is a test on the distribution of profit. A large losing day is handled by the daily loss limit instead.
Can I fail an evaluation because of consistency?
On plans where it applies at evaluation, a pass can be withheld until the distribution satisfies the rule. Whether that is a failure or a delay is published per firm.
Is a higher percentage more generous?
Yes, on that field. A 50% rule allows a single day to be half the total; a 30% rule allows a third, which is materially stricter.
Why does Rex show "scope not published" so often?
Because most firms state the percentage on the pricing page and put the scope in a document Rex has not reached. It is a real gap, so it lowers Data Confidence rather than being filled in.
