Short answer
No single trading day can represent more than 15% or 20% (depending on your account) of your total profit in the current payout cycle at the time you request a payout. This is a soft rule. It can delay your payout, but it never breaches your account, never closes your account, and never reduces your balance. You simply keep trading until the ratio balances out.
The Best Day Rule is the rule. The percentage you see in your dashboard is the live result of that rule, showing where your single biggest day currently sits against your limit.
What the Best Day Rule is, in plain terms
The Best Day Rule looks at how your profit is spread across your trading days. It asks one question: how much of your total profit came from your single best day? If too much came from one day, the rule asks you to keep trading and spread your results across more days before you withdraw.
It is not a target you have to beat, and it is not a penalty. It is a measure of distribution. A trader who earns a little across many days has shown a repeatable method. A trader who earned almost everything in one session has not shown that yet. The Best Day Rule is how we tell those two apart, and it is why the rule rewards steady performance rather than a single lucky day.
How it is calculated, and why it works this way
The calculation is one simple division. When you request a payout, we look at every trading day in your current payout cycle, take your single most profitable day, and divide it by your total profit for the whole cycle:
Best Day % = (Your highest single day profit ÷ Your total profit in the cycle) × 100
Then we compare that percentage against your limit (15% or 20%, depending on your program).
If the result is at or under your limit, your distribution is healthy and you are eligible.
If the result is above your limit, one day is carrying too much of your profit, and the payout waits until you bring the ratio down.
Why a division? Because the rule is about proportion, not about the size of any single number. A $5,000 day is perfectly fine on an account that made $50,000 in total (that is 10%), and a problem on an account that made $8,000 in total (that is 62.5%). The same day can be healthy or not depending on how much surrounds it. Dividing the best day by the total is the cleanest way to express "what share of everything came from this one day," and that share is exactly what the rule cares about.
Why the highest day? Because the rule is protecting against over-reliance on a single outlier session. The day most likely to break the rule is always your biggest one, so that is the day the rule measures. If your biggest day is within the limit, every smaller day is automatically within it too.
The number you divide by is your total profit, never your withdrawal
The bottom of the fraction is always your full cycle profit. The amount you choose to withdraw has no effect on the calculation at all. Requesting a smaller payout will not change your Best Day percentage, because the formula never looks at how much you ask to take out. The full cycle profit is always the denominator. This is one of the most common misunderstandings, so it is worth stating plainly: a smaller withdrawal request does not help.
Reading the percentage: what each range means
At or under your limit (for example 18% on a 20% account): healthy distribution, you are eligible.
Over your limit but under 100% (for example 60%): one day is too large a share of your total. Keep trading, grow the total, and that day's share will fall.
Exactly 100%: you have only had one profitable day so far, so that day is all of your profit. Normal at the start of a cycle.
Over 100%: losses on other days have made your total profit smaller than your single best day. Normal when you have losing days. It means your profit is heavily concentrated in one day.
Negative: your total profit for the cycle is currently negative, so the division produces a negative number. The rule is not meaningful while your account is net-negative on the cycle.
In every one of these cases the meaning and the action are the same: if you are over your limit, your profit is too concentrated in one day, or your total is too small or negative, and the answer is to keep trading so the total grows and your biggest day becomes a smaller share of it.
Example 1: Rule respected (20% limit)
Six profitable days, evenly distributed.
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, and 1,900 ÷ 10,000 × 100 = 19.0%. Under 20%, so the payout is available. This is what healthy distribution looks like. No single day carries the account.
Example 2: Same total, one big day (20% limit)
The total profit is identical to Example 1, but it was earned very differently.
Day | Profit | % of total |
Day 1 | +$6,000 | 60.0% |
Day 2 | +$1,000 | 10.0% |
Day 3 | +$1,000 | 10.0% |
Day 4 | +$800 | 8.0% |
Day 5 | +$700 | 7.0% |
Day 6 | +$500 | 5.0% |
Total | $10,000 | /// |
The total is still $10,000, but Day 1's $6,000 is 6,000 ÷ 10,000 × 100 = 60.0% of it, far above the 20% limit. The payout is blocked even though the total profit is exactly the same as Example 1. This shows the whole point of the rule: it is not about how much you made, it is about how evenly you made it. To fix this, keep trading and grow the total while keeping each new day below $6,000, until that day falls to 20% or less.
Example 3: Losing days make it worse
This catches many traders off guard. Losing days reduce your total profit, which makes your best day's percentage larger, not smaller.
Day | Profit | % of total |
Day 1 | +$3,000 | 75.0% |
Day 2 | -$2,000 |
|
Day 3 | +$1,500 | 37.5% |
Day 4 | +$1,200 | 30.0% |
Day 5 | -$500 |
|
Day 6 | +$800 | 20.0% |
Total | $4,000 |
|
Your winning days add up to $6,500, but after the losses your total is only $4,000. Day 1's $3,000 now represents 3,000 ÷ 4,000 × 100 = 75.0% of the total, far above the 20% limit, so the payout is blocked.
Without the losses, your total would be $6,500 and Day 1 would be 46.2%. Still over the limit, but much closer. Losing days do not help, they hurt. They shrink your total profit while your best day stays the same, pushing your best-day percentage even further past the line. Only profitable days bring the percentage down.
Example 4: After your first trading day (shows 100%)
On the very first profitable day of a cycle, your Best Day percentage will always show 100%.
Day | Profit | % of total |
Day 1 | +$1,200 | 100.0% |
Total | $1,200 |
|
With only one day of profit, that day is all of your profit. 1,200 ÷ 1,200 × 100 = 100%. This is completely normal. As you add more profitable days, the percentage falls. It does not mean you are failing the rule. It simply means you have only traded one day so far.
Example 5: Above 100% (best day larger than total)
When losses have shrunk your total below your single best day, the percentage goes above 100%.
Day | Profit | % of total |
Day 1 | +$3,000 | 150.0% |
Day 2 | -$1,500 |
|
Day 3 | +$500 | 25.0% |
Total | $2,000 |
|
Best day is $3,000, total is only $2,000. 3,000 ÷ 2,000 × 100 = 150%. A figure over 100% is normal and expected here. It is the maths telling you your profit is heavily concentrated in one day, and that you need more profitable days for the total to grow past that one day. Nothing is broken. The fix is always the same: keep building profit on your other days.
Example 6: A negative percentage (account net-negative on the cycle)
This is the result that confuses people the most, so here is exactly what is happening.
The formula always uses your real total profit as the number you divide by, with its real sign. It does not use absolute values, it does not remove the minus sign, and it never substitutes your biggest losing day in place of your biggest winning day. It is always your highest profitable day divided by your true net total.
Day | Profit |
Day 1 | +$1,047 |
Day 2 | -$2,533 |
Day 3 | +$1,005 |
Total | -$481 |
Best Day % = 1,047 ÷ -481 × 100 = approximately -217.67%.
A negative percentage is not an error. Your total profit for the cycle is negative, which means your account is currently down on the cycle, and so dividing a positive best day by a negative total produces a negative number. While your total is negative, the Best Day Rule is simply not meaningful yet. It becomes relevant again the moment you trade back into positive total profit. The action is straightforward: keep trading until your cycle total is positive, and the percentage will become a normal positive figure again.
Example 7: A very large percentage while climbing out of a loss
This is directly connected to Example 6. As an account recovers from a loss back into profit, the total profit passes through very small numbers on its way up. Dividing your best day by a tiny total produces a very large percentage.
Suppose your best profitable day was +$1,008 and, after several losing days, your total has just climbed to +$198.
Best Day % = 1,008 ÷ 198 × 100 = approximately 509.09%.
Now add one more solid profitable day so the total grows to +$538.
Best Day % = 1,008 ÷ 538 × 100 = approximately 187.36%.
Nothing changed in the formula. Your total simply grew, and the percentage dropped.
A figure like 509% is real and correct: moving from a very small total to a larger one is a large proportional move, not zero. It is not a dashboard error. It is the rule behaving exactly as designed, and it resolves itself naturally as your total profit grows.
The single most important thing to understand
The Best Day percentage is not a random number that you must pass. It is the result of one simple division that measures how evenly your profit is spread. A number over your limit, a number over 100%, and a negative number are all normal outputs of the same formula in different situations. In every case the meaning is the same and the action is the same: your profit is too concentrated in one day, or your total is still too small or negative, and the answer is to keep trading steadily so the total grows and your biggest day becomes a smaller share of it.
How to fix a percentage that is over the limit
Focus on increasing your total profit while keeping each day's gain below your current best day. This keeps the number on top of the fraction (your best day) steady while the number on the bottom (your total profit) grows, which pulls the percentage down.
You can calculate exactly how much total profit you need:
Minimum total profit needed = Your best day profit ÷ Your Best Day limit (as a decimal)
20% limit: a $3,000 best day needs at least $3,000 ÷ 0.20 = $15,000 in total cycle profit before that day falls to 20%.
15% limit: the same $3,000 best day needs at least $3,000 ÷ 0.15 = $20,000 in total cycle profit before that day falls to 15%.
Practical guidance:
Keep your daily gains below your current best day, so you do not simply replace one outlier with another, even larger one.
Avoid losing days where you can, since they shrink your total and push the percentage back up.
Trade at your own pace. There is no deadline, and the percentage updates live in your dashboard as you go.
When does it reset?
After every successful payout. Your next payout cycle starts completely fresh. This resets the total profit calculation, the best day figure, and all trading day data.
Nothing carries over from the previous cycle. Only new trading days, opened after your last payout, count toward the next one.
What is not allowed
Attempting to bypass the Best Day Rule is not permitted and may result in partial payout approval, payout denial, or account suspension. This includes:
Splitting large winning positions into smaller partial closures to spread one day's profit across several days
Placing small trades to create artificial trading days and dilute the best day percentage
Hedging to control when profit is realized
Splitting trades across midnight to distribute profit between two calendar days
If detected, the entire trade may be treated as a single transaction for evaluation purposes, and the bypass attempt itself may trigger corrective action on the account.
Where does it apply
The Best Day Rule applies in the funded phase of challenge programs and from the start in instant funding programs. It does not apply during challenge evaluation phases. Some time-limited programs use a different metric called the Best Trade Rule, which limits individual trades rather than trading days. For your exact percentage and where it applies, refer to your program's rules page or the figure shown in your dashboard.
Common questions
Does it breach my account? No, never. It is a soft rule. It only delays your payout. Your account stays fully active, your profit stays intact, and you can keep trading.
Can I request a payout if I am 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 bring the percentage down? No. They reduce your total profit, which makes the ratio worse. Only profitable trading days bring it down.
Does requesting a smaller payout lower the percentage? No. The percentage is always based on your full cycle profit, never on the amount you request to withdraw.
Why does it show 100% after one day? With only one profitable day, that day is 100% of your profit. This is normal and decreases as you add more profitable days.
Why is it above 100%? Losses on other days have made your total profit smaller than your single best day. A figure above 100% means your profit is concentrated in one day. Keep trading to grow the total.
Why is it negative? Your total profit for the cycle is currently negative, so the formula produces a negative number. It is not meaningful while your account is net-negative on the cycle. Trade back into positive total profit and it becomes a normal percentage again.
Why did it suddenly jump to a very large number like 500%? Your total profit just climbed from a loss into a small positive figure. Dividing your best day by a small total gives a large percentage. As your total grows with more profitable days, the percentage falls. This is expected and not a dashboard error.
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 steadily until your total profit reaches that number, keeping each new day below your best day.
