When you request a payout, we look at every day you traded since your last payout and find your single most profitable day. That day's profit is compared to your total profit for the same period.

If your best day is 20% or less of your total profit, you pass. If it is more than 20%, you are not eligible to withdraw yet. On Thunderbolt Legacy the threshold is 30% instead of 20%.

The formula: best day profit divided by total profit must be 20% or less (or 30% or less on Legacy).

The Best Day Rule rewards steady, repeatable trading over one lucky session. A funded account is meant to prove you can produce profit with discipline, not that you hit a single outsized day and stopped. Spreading your profit across several days shows a process we can keep paying out on.

Because it only gates payouts and never fails the account, it adds no risk to your capital. It simply asks you to build a balanced track record before you withdraw.

Say you are on a funded account and want to request a payout. Since your last payout you have five profitable days:

Your total profit is $4,000. The 20% limit means your best single day can be no more than $800 (20% of $4,000).

Your best day is Monday at $1,800, which is 45% of the total. That is over the limit, so you are not eligible to withdraw yet.

You keep trading and add balanced days until your best day fits inside the limit. You do not need to beat the $1,800 day, you need to raise the total around it.

The target total. For a $1,800 best day to equal exactly 20% of the total, your total profit needs to reach $9,000 ($1,800 / 0.20). So you add another $5,000 of profit, spread across more days, without beating that $1,800 day.

A concrete path. Add four more days of $1,250 each. Total profit becomes $9,000, your best day is still $1,800, and $1,800 is now exactly 20% of $9,000. You pass and can request the payout.

On Legacy it is easier. The same $1,800 day only needs a total of $6,000 to fit, because the limit is 30% ($1,800 / 0.30).

The rule is easy to stay ahead of when you plan for it before you request a payout, not after a big day.

Aim for five to six solid days. If your best day is roughly one fifth of your total, you are already at the 20% line. More days give you more room.

Cap your best day mentally. If you are targeting a $5,000 profit run, no single day should carry more than $1,000 of it (20% of $5,000). When a day runs hot, bank the win and protect it rather than pushing further.

Do not stop after one big day. A single large day is the most common reason a payout is delayed. Keep adding balanced days until the ratio works.

Check the math before you request. Divide your best day by your total. If it is above 20% (30% on Legacy), keep trading first.

The Best Day Rule is one of several conditions you meet to request a payout. All of them must be true at the same time:

At least 1% profit since your last payout. On a $50,000 account that is $500; on a $100,000 account it is $1,000.

Your best day within 20% of total profit (30% on Legacy). This is the Best Day Rule.

All positions closed at the time you request.

A minimum payout of $100 (that is your 99% share).

There is no fixed payout schedule. Once every condition above is met, you can request at any time.

Rules like this vary between firms, and some check them differently or not at all. Upcomers Futures checks it at payout: 20% on Classic and Vanguard, 30% on Legacy. If you passed elsewhere with a day like the 45% one above, plan for more balanced days here before your first withdrawal.

The upside is that it is soft. Hard breaches close the account automatically: a drawdown breach, or a Max Trade Loss violation (a single trade past 1.5% of your account size on Classic and Vanguard, or 2% on Legacy). On a $50,000 Classic account that 1.5% cap is $750 per trade. The Best Day Rule is different. Going over the limit never fails or closes your account. It only means you keep trading a little longer before you withdraw.

Does the Best Day Rule ever fail my account?

No. It is soft. It only delays a payout until your profit is more balanced. It never breaches or closes the account. That is different from the hard rules (drawdown limits and the Max Trade Loss, 1.5% on Classic and Vanguard, 2% on Legacy), which do close the account when broken.

What counts as my total profit?

Your net profit since your last payout. Your single most profitable day in that period is compared to that total.

Does it apply during the challenge?

No. It only applies to funded accounts when you request a payout. Vanguard is instant funding, so it applies there from your first payout.

What is the limit on each program?

20% on Thunderbolt Classic and Vanguard, 30% on Thunderbolt Legacy.

Can I place small trades to add days and fix the ratio?

No. Placing token trades to create artificial days is treated as bypassing the rule. It does not work (those trades can be counted as a single day) and can delay or deny your payout. Add real, balanced trading days instead.
