- A consistency rule caps how much of your profit can come from your single best day. Break it and you usually don’t fail; you just have to keep trading until the maths works.
- The profit you need is best day ÷ rule %. A $1,500 day under a 30% rule means you need $5,000 total, not $3,000.
- Every extra dollar you must make is more time exposed to the drawdown floor. The cheapest fix is a daily profit cap you set before the session.
Consistency rules exist because firms don’t want to fund one lucky day. They are also the rule traders most often misread: almost nobody fails an evaluation outright for breaking one, but thousands of passes and payouts are delayed by them, and every extra day of trading is another day the drawdown floor can catch you.
The two kinds of consistency rule
1. Best day as a share of total profit (most futures firms)
Your largest winning day may be at most a set percentage of your total net profit for the period. If it’s bigger, you keep trading until total profit is large enough. This is the version used, in the evaluation or at payout, by most firms on this site:
| Rule | Firms and when it applies |
|---|---|
| 50% | Apex (when you request a payout), Take Profit Trader (Test), MyFundedFutures (evaluation), LucidFlex (evaluation) |
| 40% | Tradeify Select (evaluation), Legends Trading Elite, FundedNext Futures (challenge), Funded Futures Network and Alpha Futures (funded payouts) |
| 35% | Bulenox, E8 Futures (funded stage) |
| 55% | BluSky (evaluation; 34% in the buffer) |
| 30% | TradeDay, Earn2Trade, Phidias (funded cash accounts) |
| 25% | Top One Futures (funded) |
| None | Purdia Capital, Alpha Futures and E8 Futures in the evaluation, most forex two-step challenges |
2. Best day as a share of the target (Topstep)
Topstep compares your best day with the profit target instead. Keep your best day under 55% of the target. If one day goes over, you don’t fail; the target rises so that your best day fits, roughly to best day ÷ 0.55. Topstep’s dashboard shows the exact new figure.
The one formula you need
Here is what a single big day does to a $3,000 target:
| Best day | 50% rule | 40% rule | 35% rule | 30% rule |
|---|---|---|---|---|
| $900 | $3,000 | $3,000 | $3,000 | $3,000 |
| $1,200 | $3,000 | $3,000 | $3,429 | $4,000 |
| $1,500 | $3,000 | $3,750 | $4,286 | $5,000 |
| $2,000 | $4,000 | $5,000 | $5,714 | $6,667 |
| $2,500 | $5,000 | $6,250 | $7,143 | $8,333 |
A $2,500 day feels like most of the job done. Under a 30% rule it raises the bar to $8,333, nearly three times the original target, while your drawdown is still $2,000.
Why a big day is a trap
Say you’re at TradeDay (30% rule) on a $50K account and you make $2,000 on day two. You now need $6,667 in total, so another $4,667 on top of what you have. At a steady $400 a day that’s about 12 more sessions, every one of them a chance to hit the drawdown floor.
Worse, the extra profit must itself be spread out: if day three is another $2,000, the best day is still $2,000 and the requirement doesn’t move. The way out is many modest days, which is exactly what the rule is designed to force.
Set a daily profit cap before the session
Work backwards from the rule and the target to the largest day you can bank without raising the bar:
| Target | 50% | 40% | 35% | 30% |
|---|---|---|---|---|
| $1,500 (25K) | $750 | $600 | $525 | $450 |
| $3,000 (50K) | $1,500 | $1,200 | $1,050 | $900 |
| $6,000 (100K) | $3,000 | $2,400 | $2,100 | $1,800 |
| $9,000 (150K) | $4,500 | $3,600 | $3,150 | $2,700 |
In practice, set your working cap 10–15% below that figure. Fast markets overshoot targets, and a trailing exit can add a few hundred dollars after you decide to stop.
Turning the cap into a plan
- Minimum days follow from the cap. Under a 30% rule you can’t pass in fewer than four winning days, because three capped days only reach 90%.
- Losing days don’t help. They reduce total profit, which makes your best day a larger share. A $1,000 best day is 33% of $3,000, but if a losing day takes your total back to $2,500 it becomes 40%.
- Watch the definitions. Most firms measure against net profit for the period, which includes losing days. Some count the evaluation only, some each payout cycle. Check the wording on your firm’s page before you plan.
At payout: the rule that resets every cycle
Firms that apply the rule when you request a payout (Apex at 50%, Alpha Futures and Funded Futures Network at 40%, E8 Futures at 35%, Top One at 25%) usually measure each payout cycle separately. That means the cap applies again from zero after every withdrawal. A trader who banks $1,800 on the first day of a cycle at a 40% firm needs $4,500 of cycle profit before they can withdraw anything.
Our guide to the funded stage covers payout buffers and caps, which interact with this rule.
Check your own days
Paste or type your daily profit and loss, pick a rule, and the checker shows your best-day share, how much more you need, and the largest day you can bank tomorrow without moving the goalposts.
Your best day is too large a share. You need $1,850 more profit, spread over days of no more than $1,600 each, so your best day stays the largest.
Pre-trade checklist
- Write down your firm’s rule, and whether it applies in the evaluation, at payout, or both.
- Calculate today’s cap from the formula above, minus a 10–15% safety margin.
- Set a platform alert or a hard profit-taking rule at that level.
- After a losing day, recompute: the cap on your share doesn’t move, but the room before you breach it does.
