This article covers the Best Day rule (based on a calendar day). A few time-limited programs instead use a Best Trade rule, which caps a single trade rather than a single day - check your program rules for which one applies to you.
No single trading day can account for more than 15–20% of your total profit (the exact limit depends on your account) at the time of payout. If one day goes over the limit, only your payout is delayed - your account stays fully active. Keep trading; once enough other profitable days accumulate, the ratio rebalances and you can request a payout.
How It Works
For every trading day in your current payout cycle:
Day % = (that day's net P&L ÷ total net P&L across the cycle) × 100
We take the largest of those daily percentages - that's your Best Day %. It's compared against your account's limit (e.g. 20%). Both numerator and denominator are net values (wins minus losses). Days run on UTC (00:00–23:59).
Example 1: Rule Respected (20% limit)
Day | Profit | % of Total |
Day 1 | +$1,900 | 19.0% |
Day 2 | +$1,800 | 18.0% |
Day 3 | +$1,700 | 17.0% |
Day 4 | +$1,600 | 16.0% |
Day 5 | +$1,500 | 15.0% |
Day 6 | +$1,500 | 15.0% |
Total | $10,000 |
|
Best day is $1,900 = 19.0% of $10,000. Under 20%. Payout available.
Example 2: Losing Days Make It Worse
A losing day doesn't pull your Best Day down - it pulls your total down, which makes every winning day's share bigger.
Day | Profit | % of Total |
Day 1 | +$3,000 | 75.0% |
Day 2 | -$2,000 | (loss - see below) |
Day 3 | +$1,500 | 37.5% |
Day 4 | +$1,200 | 30.0% |
Day 5 | -$500 | (loss) |
Day 6 | +$800 | 20.0% |
Total | $4,000 |
|
Winning days alone add up to $6,500, but the losses bring the total down to $4,000. Day 1's $3,000 is now 75% of total - well over the 20% limit. Without the losses it would've been 3,000 ÷ 6,500 = 46.2% - still over, but much closer.
Example 3: When your account is in net loss
If your total profit is negative, the formula produces strange-looking numbers. A losing day divided by a negative total comes out positive - and often very large.
Days: +$1,047, –$2,533, +$1,005 → total = –$481
Day | Net P&L | day/total x 100 |
1 | +$1,047 | –218% |
2 | –$2,533 | +527% ← shown as "Best Day" |
3 | +$1,005 | –209% |
Here "Best Day %" no longer points to your actual best day - the math just breaks down when the total is negative. You can't request a payout in net loss anyway, so this number blocks nothing new. Treat it simply as: not enough profit yet.
How to read your Best Day
Account state | What the number means |
1 trading day so far | Always 100% - that day is your entire profit |
Several profitable days, total > 0 | A real ratio between 0 % and 100 %. Aim under your limit |
Total > 0 but losses on some days | Can exceed 100% - winners are large relative to a shrunken total |
Total ≤ 0 | Number is mathematically meaningless. Treat as: "not enough profit yet" |
How to bring the ratio down
You can't shrink your Best Day after the fact - only grow the denominator. Trade more profitable days, each smaller than your current best day.
Minimum total profit needed = best-day profit ÷ your limit
A $3,000 best day with a 20% limit needs at least $15,000 total profit ($3,000 ÷ 0.20). Losing days do the opposite - they shrink your total and push the ratio further from where you want it.
When Does It Reset?
After every successful payout. The next cycle starts at zero - previous days, total, and Best Day % don't carry over.
Where the rule applies
Funded phase of challenge programs
From day one in instant-funding programs
Not during the evaluation phase of challenges
Some time-limited programs use a Best Trade Rule instead (limits a single trade, not a single day) - check your program rules for the exact figure
What Is NOT Allowed
Attempting to dilute the Best Day % artificially is prohibited and may result in partial payout, denial, or suspension:
Splitting one winning position into multiple partial closures across days
Placing small filler trades to manufacture extra "trading days"
Hedging to control when profit is realized
Splitting a trade across midnight to spread profit between two calendar days
If detected, we may evaluate the related trades as a single transaction.
Common Questions
Does it breach my account?
No, never. It's a soft rule. It only delays your payout. Your account stays fully active.
Can I request a payout if I'm over the limit?
No. You need to be at or under your limit first. Keep trading to bring the ratio down.
Do losing days help?
No. They reduce your total profit, which makes the ratio worse. Only profitable trading days help balance it out.
What timezone is used?
UTC. A trading day runs from 00:00 UTC to 23:59 UTC.
I had one amazing day. What now?
Your account is safe. Use the formula: best day profit / your limit = minimum total profit needed. Then keep trading consistently until you reach that number.
