The Consistency Rule Rarely Fails Accounts
Almost every explanation treats it as a pass or fail test on your best day. At most firms it is not. It blocks the payout until your profit spreads out, which is a different problem with a different fix.
A trader hits the profit target in three weeks, requests a payout, and gets told the request is blocked. Nothing was breached in the sense they expected. No rule was broken, the account is still live, and the money is still there. One day just produced too large a share of the profit.
What It Measures
The consistency rule caps how much of your total profit can come from your single best day. It exists so an account cannot qualify on one outsized position. The calculation is the same wherever you see it, and only the threshold changes.
Total profit 10,000 best day 4,000 ratio 40%
Against a 30% limit result over the line
Against a 40% limit result exactly at the line
That is the whole mechanic. The interesting part is not the formula, it is the three things firms do differently around it, because those decide whether the rule ever touches you at all.
What Actually Happens When You Breach
This is the part that gets stated wrongly most often. Going over the consistency threshold usually does not fail your account. It gates your payout until the ratio comes back inside the limit.
Phidias states this plainly in its own documentation. Its guide says that if you breach the rule your account is not failed and you simply need more profit to dilute the ratio before requesting a payout. That is a delay, not a loss. The account keeps trading and the profit stays in it.
The practical difference is large. A trader who believes a consistency breach kills the account will often stop trading, or worse, take a reckless position to force a resolution. A trader who understands it as a payout gate keeps trading normally and the problem solves itself. Compare that to a drawdown breach, which genuinely does end the account. We cover that in trailing versus static drawdown.
Do not assume it works this way everywhere
Payout gating is the common treatment, not a universal one. Some firms do treat a consistency breach as an evaluation failure. The rulebook will say which, and the distinction is worth finding before you take a large position rather than after.
When The Rule Applies
A consistency rule can attach at three different points, and firms pick different combinations. It can apply during the evaluation, on the funded account, or only at the moment you request a payout.
Phidias lists its evaluation threshold as zero, meaning the rule does not constrain the challenge phase at all and only appears later. Tradeify takes a different approach and sets the threshold by account type rather than by phase, applying 35% on its Advanced and Growth Sim Funded accounts and 20% on Straight to Sim Funded accounts. Same rule name, different attachment point, different effect on how you trade.
This is why comparing consistency percentages between firms without checking the phase is misleading. A 20% rule that only applies at payout is easier to live with than a 35% rule that governs the evaluation. Details for both firms are in our Phidias review and Tradeify review.
Best Day Or Single Trade
The third axis. Most firms measure your best trading day. Some measure your single largest trade. The difference matters enormously depending on how you trade.
If the rule measures the day, a scalper taking thirty small trades is nearly immune, because no single day concentrates much profit unless the whole day ran hot. If it measures the trade, that same scalper is fine but a swing trader holding one position through a move is exposed, since one trade may be most of the month. The same threshold is generous or brutal depending on which basis it uses and which style you run.
| Axis | Options seen | Why it matters |
|---|---|---|
| What it measures | Best day, or single largest trade | Decides whether scalpers or swing traders are exposed |
| When it applies | Evaluation, funded account, or payout request only | A payout-only rule barely affects how you trade |
| Breach consequence | Payout delayed, or evaluation failed | The difference between a wait and a lost account |
Thresholds In Practice
Published thresholds at the two firms cited above run from 20% to 35%. Phidias sets its own at 30% and characterises 20% as the harder setting used elsewhere. Treat any range you read, including this one, as a sample rather than a market standard, because these numbers change and firms rarely announce it.
We are not publishing a table of thresholds across every firm we cover. Doing that properly means verifying each firm’s current rulebook, and a stale consistency table is worse than no table, since a trader will size a position against it. Check the firm’s own terms, then run your numbers through our consistency calculator.
If you are setting a consistency rule rather than trading under one, the threshold is a pricing decision and not a discipline policy. A tighter rule cuts payout liability but shows up in reviews. We cover that trade-off in how to start a prop firm.
How To Fix A Breach
Where the rule gates payouts rather than failing accounts, a breach is arithmetic and the fix is arithmetic. You need enough additional profit that your best day stops dominating the total.
Best day 4,000 total 10,000 ratio 40% blocked
Required total at 30% = 4,000 ÷ 0.30 = 13,334
Additional profit needed = 13,334 − 10,000 = 3,334
and the new profit must not create a new best day above 4,000
That last line catches people. Fixing a consistency breach with one more big day does not work, because the new day becomes the numerator. The fix is a run of ordinary days, which is exactly the behaviour the rule was written to produce.
Common Questions
Does breaching the consistency rule fail your account?
Usually not. At most firms it blocks a payout request until additional profit dilutes the ratio, and the account keeps trading. Phidias states this explicitly in its own guide. Some firms do treat it as an evaluation failure, so confirm it in the rulebook.
How is the consistency rule calculated?
Best day profit divided by total profit, times 100. If your best day is 4,000 of a 10,000 total, your ratio is 40%. Only the permitted threshold differs between firms.
Does the consistency rule apply during the evaluation?
It depends on the firm. Phidias lists a zero threshold for the evaluation phase, meaning the rule does not apply there. Other firms apply it throughout, and some set it by account type instead of by phase.
Which prop firms have no consistency rule?
Some firms operate without one, and it is a common thing to search for. We are not listing them here from memory, because a rule can be added at any time and an out of date list would cost a trader real money. Check the current rulebook of any firm on our reviews index before you buy.
