A prop-firm consistency rule measures whether too much of an account's result came from its best trading day. It can affect evaluation, funded-stage eligibility, or a payout request. The percentage alone is incomplete: a 50% rule can compare the best day with Positive Days' Profit at 1 firm and with a fixed Profit Target at another.
- Identify the stage. The rule may apply during evaluation, after funding, before a payout, or in more than 1 stage.
- Find the denominator. Total net profit, Positive Days' Profit, and a fixed Profit Target produce different answers.
- Read the consequence. Exceeding a threshold can extend the target or delay eligibility rather than automatically breach the account.
- Treat each product separately. FTMO 1-Step records a 50% Best Day rule, while FTMO 2-Step explicitly does not apply that objective in the current capture.
- Do not confuse rule families. Best-day, lot-size, profitable-day, and strategy-consistency conditions are separate tests.
What is a prop-firm consistency rule?
A best-day consistency rule compares the account's most profitable closed trading day with a named profit base. A product can use that calculation to decide whether the evaluation is complete or whether a reward can be requested. The named day boundary, open-position treatment, reset event, and required inequality can all change the result.
There is no safe firm-wide shortcut. Current captures show a 50% Best Day rule on FTMO 1-Step but no Best Day objective on FTMO 2-Step; FundingPips applies a 35% score only to the On Demand reward cycle on 2-Step Standard; and FXIFY applies its 25% Two Phase Classic percentage only in the funded stage. The exact product and stage matter more than the brand name.
The 6 fields that define the rule
| Field | Question to answer | Why it changes the result |
|---|---|---|
| Stage | Evaluation, funded account, payout, or scaling? | A 25% funded rule can be N/A during 2 evaluation phases. |
| Numerator | Best closed day, largest trade, or another result? | A best-day test is not a lot-size test. |
| Denominator | Net profit, positive-day profit, or Profit Target? | The same $3,000 day can pass 1 formula and miss another. |
| Threshold | Below, at or below, or no more than the percentage? | A strict “below 50%” boundary differs from “no more than 50%.” |
| Consequence | Breach, delayed payout, extra profit, or a higher target? | Exceeding the figure does not always close the account. |
| Cutoff and reset | Which timezone closes the day, and when does the calculation restart? | Trades spanning 00:00 or a payout can move between calculation windows. |
If any 1 of these 6 fields is missing, do not reverse-engineer it from a percentage badge. Record the missing field and confirm it in the product's current rules before paying or requesting a reward.
Three consistency-rule structures
1. Best day divided by an applicable profit total
When the product explicitly uses a profit-share formula, the calculation is best-day profit / applicable profit total x 100. FTMO 1-Step names Positive Days' Profit as the denominator. Topstep's XFA Consistency payout path instead records total profit and a 40% limit. Those denominators should not be silently treated as identical.
2. Best day compared with a fixed target
Topstep's Trading Combine now publishes a 55% Consistency Target, rechecked on 2026-10-06. A best day above that share of the initial Profit Target raises the required target; the consistency guide also calculates the best day as a share of total profit and says there is no buffer. The remaining profit needed to resolve an excess must be earned in a separate trading session. The funded XFA Consistency payout route remains a distinct 40% test.
3. A published score with product-specific eligibility
Some current product pages publish a percentage without enough captured text to reconstruct the complete formula. FundingPips Zero records a 15% maximum Consistency Score as a reward condition, while FXIFY Two Phase Classic records 25% only for the funded stage. In those cases, the honest calculation is “not fully captured,” not a guessed best-day denominator.
A lot-size consistency rule is separate. It can compare position sizes, contracts, or risk per trade even when a product has no best-day percentage. Likewise, a minimum profitable-day condition counts qualifying days; it does not calculate the share contributed by the largest day.
Current product examples: 15% to 55% does not mean the same thing
| Product | Published rule | Stage and denominator | Captured consequence or caveat | Captured |
|---|---|---|---|---|
| FTMO 1-Step | 50% Best Day rule | Challenge and reward; Positive Days' Profit | Continue earning profit until no single day exceeds 50% | 2026-09-29 |
| Topstep Standard Path | 55% Consistency Target | Trading Combine; Profit Target | A larger best day can increase the Consistency Target | 2026-10-06 |
| Topstep XFA Consistency path | 40% best-day limit | Payout path; total profit | Also requires at least 3 trading days with 1 trade per day | 2026-10-06 |
| FundingPips Zero | 15% maximum Consistency Score | Reward eligibility; full denominator not recorded | Also records 7 profitable days of at least 0.25% in each rolling 30-day period | 2026-09-29 |
| FXIFY Two Phase Classic | 25% Consistency Rule | Funded stage only; N/A in Phase 1 and Phase 2 | Full denominator is not recorded in the current capture | 2026-09-15 |
| FundedNext Stellar Instant | No consistency rule in the captured official FAQ | Phase-0 simulated instant-funded product | Still has a 6% trailing maximum loss and separate payout gates | 2026-09-29 |
The My Funded Futures review is a useful same-firm stage comparison. Rapid and Pro apply a captured 50% rule during evaluation, Rapid EOD uses 30% during evaluation, Flex is now legacy, and Builder records no evaluation percentage but a 50% rule after funding. The percentage and stage must be read together.
The table is a dated product snapshot, not a permanent firm list. Use the product comparison for the current structured fields and the challenge-change ledger for material rule updates. A null percentage means no verified numeric field unless the source explicitly says the rule does not apply.
Consistency-rule calculator: the best-day share formula
This worked example applies only when the firm's rule explicitly uses best day / applicable profit total. Assume the best day is $1,200, the current applicable profit total is $3,000, and the maximum is 30%.
| Current consistency | $1,200 / $3,000 x 100 = 40% |
|---|---|
| Maximum allowed | 30% |
| Required applicable profit total | $1,200 / 0.30 = $4,000 |
| Additional applicable profit needed | $4,000 - $3,000 = $1,000 |
The reusable formula is required applicable profit = best-day profit / decimal limit. Then calculate additional profit = max(0, required applicable profit - current applicable profit). If a later day exceeds $1,200, the numerator changes and the calculation must be run again.
Topstep's Combine consequence differs from a payout eligibility check. On the captured $100K Standard Path, the initial Profit Target is $6,000 and its current 55% recommendation is $3,300. A $3,500 best day exceeds that recommendation and raises the required target; it is not an automatic account failure. Extra profits in that same session also enlarge the best day, so they cannot resolve the excess.
How consistency interacts with drawdown and overtrading
Consistency does not replace daily or maximum loss. A trader can be below a 30% best-day cap and still breach a 4% trailing loss boundary. Conversely, one large profitable day can preserve the loss buffer but delay evaluation or payout eligibility. The drawdown guide explains why static, intraday-trailing, and end-of-day-trailing floors need separate calculations.
Trying to “dilute” a large best day by forcing extra trades can create plan drift. Additional low-quality orders add spread, commission, and loss exposure; they do not guarantee that the applicable profit denominator will rise. A pre-written session stop remains binding even when the consistency score is above its threshold.
The cash consequence also depends on stage. A payout-only rule can leave evaluation status unchanged while delaying realised income. The net-cash profitability test counts a reward only when approved and received, not when dashboard profit first appears.
A pre-purchase and daily consistency worksheet
| When | Record | Control |
|---|---|---|
| Before checkout | Exact product, stage, numerator, denominator, percentage, consequence, and source date | Do not buy if the formula is material to the strategy but remains unclear |
| Before session | Current best day, applicable profit base, rule headroom, session-risk stop | Keep the personal stop below the firm's breach boundaries |
| After session | Closed-day profit, new best day, recalculated score, remaining target | Use the firm's timezone and dashboard cutoff |
| Before payout | Consistency, profitable days, safety cushion, minimum reward, KYC, and open positions | Treat every named gate as independent until approved |
The broader challenge risk-plan worksheet converts firm limits into pre-session controls, while the challenge lifecycle shows where evaluation, funded status, payout eligibility, and cash receipt separate.
Frequently asked questions
What is the consistency rule in a prop firm?
It is a product rule that measures profit concentration, commonly using the best trading day. The calculation can compare that day with Positive Days' Profit, total profit, or a fixed Profit Target, and it can apply during evaluation or before a payout.
How do I calculate a 30% consistency rule?
Only for a best-day share formula, divide the best-day profit by the firm's named applicable profit total and multiply by 100. A $1,200 best day divided by $3,000 is 40%; reducing that to 30% with the same best day requires a $4,000 applicable total.
Does exceeding a consistency percentage fail the account?
Not always. FTMO 1-Step says the trader must continue until the Best Day is no more than 50% of Positive Days' Profit, while Topstep's current Combine guide uses 55% and raises the required profit target after an excess. The product's stated consequence controls.
Can a losing day change the consistency score?
It depends on the denominator. A calculation based on Positive Days' Profit treats losing days differently from one based on net total profit. Do not include or exclude losses until the product terms define the applicable profit base.
Is a lot-size consistency rule the same as a best-day rule?
No. A best-day rule measures profit concentration, while a lot-size rule measures changes in position or contract size. A product may use either test, both tests, or neither.
Which prop-firm products have no consistency rule?
Current captures explicitly record no Best Day objective for FTMO 2-Step and no consistency rule for FundedNext Stellar Instant. That finding is product-specific and dated 2026-09-29; verify the live rules because another product from either firm can differ.
