A trader can reach the profit target in an evaluation and still not pass, because one big day made up too much of the total. That is what a consistency rule does, and the definition matters more than the headline percentage.
What the rule measures
A typical consistency rule limits how much one trading day can contribute to total profit. A frequently seen version is that the best day cannot exceed a set percentage, for example 30%, of total profit. Firms differ on what counts as the total, on which days are included and on whether the rule applies at evaluation, at payout or in the funded stage. The percentages below are hypothetical, so read your firm's current document for the real numbers.

Best-day share is the best single day divided by the total. Hypothetical evaluation with a $6,000 profit target and a 30% rule:
- Passing path: daily results of $1,200, $800, $600, $1,000, $900, $500 and $1,000 sum to $6,000. The best day is $1,200, which is 20% of total. It clears the rule.
- Failing path: $2,500, $800, $600, $500, $700 and $900 also sum to $6,000, but the best day is $2,500, or 41.7%. The target is met and the rule is not.
To fix the second path, total profit has to grow until the best day is at or below 30% of it. That means $2,500 divided by 0.30, which is about $8,333, so another $2,333 of profit is needed without making a bigger day. Every extra trading day also carries its own loss risk, and an evaluation fee does not cap that downside if you take more risk to finish.
Definitions change the answer
Take a hypothetical three-day sequence: +$1,200, -$400, +$800.
| Denominator | Value | Best day share |
|---|---|---|
| Net profit | $1,600 | 75% |
| Sum of winning days | $2,000 | 60% |
The same trades produce two very different ratios depending on whether the firm divides by net profit or by gross winning days. Some firms also measure from the last payout or from a funded account start date. Read the definition, find a worked example in the firm's own documentation, and run your own numbers through it. Firms can differ by product and account vintage, so make sure the document you read matches your account type. A rule on a futures evaluation is not interchangeable with a rule from a different kind of program, such as an FTMO challenge, which is a different product from exchange-traded ES and NQ evaluations.
Why traders trip it
- Sizing up on news days. Increasing size for an announcement can create one oversized day, whether it wins or not.
- Chasing after a bad start. Adding size after early losses to recover can produce a lopsided best day, or a loss-limit breach.
- Checking only near the target. If you only compute the ratio when you are close, you discover the problem too late to manage it.
A tracking sheet that works
- One row per trading day with date and net result.
- Running total, using the firm's definition.
- Best day to date and the current best-day share.
- The profit total you would need for the share to fall under the limit.
Fill it in at the end of every session. The last column is the useful one, because it turns the rule into a number of dollars and days.
Ways to structure trading around it
- Fixed daily goal. Divide the target by the days you are willing to trade. $6,000 over 20 days is $300 a day. Stopping at a goal, up or down, is a choice you make before the open. It lowers the chance of one outsized day, and it can cap upside on days the market gives you more. That trade-off is real.
- Stricter personal loss limit. A personal daily limit well inside the firm's drawdown rule leaves room for a bad day, and it takes the revenge trade off the table.
- Consistent size. Trading the same contract count each day makes daily results more comparable. It does not guarantee a given outcome.
Check the funded stage separately
Rules can change after the evaluation. A consistency requirement may apply at payout, at some stage of the funded account, or not at all. A funded account is not live trading, and payouts are not guaranteed, so read the funded terms before you rely on them. For tax, a prop payout may be treated as service or contract income and is not automatically Section 1256 gain. Ask a qualified tax professional, and see the IRS pages on Form 6781 and Topic 429 for how qualifying contracts are treated.
Automation and these rules
Consistency math is only one rule among many. Apex states that it prohibits automated or algorithmic preset bots that place, modify or cancel trades without personal real-time review. See Apex's prohibited activities page and user agreement. Do not describe any bot, YMI's included, as an Apex-compatible way to pass an evaluation. Manual trading is a different category from automation. Topstep's bot and API use depends on the account product. The TopstepX API access article describes API availability for SIM, not Live, and prohibits order transmission from a VPS, VPN or remote server, so it is personal device only. Read the current article before assuming a bot setup is permitted.
