This rule is available for E8 Zero Max and Starter in the challenge stage.
(or E8 One, E8 One Crypto in the Performance stage, which has a different article because in the performance stage, the mechanic of best day works a little bit differently).
Why it exists (your upside): Whether you are trading simulated capital with E8 or your own capital elsewhere, consistency is the only thing that scales. This rule protects you from the "one-hit wonder" syndrome, helping you develop the discipline needed to manage accounts in the long term.
Quick Explanation (Read this first)
Your profit should not exceed 40% of the total profit target in a single day. If it does, your profit target increases by the amount you made over that limit.
Plain English: stay consistent. If you have one huge profit day early on, it won't count fully toward your target. You will effectively need to hit a higher total profit until that big day no longer makes up more than 40% of your total.
Numbers in context ($6,000 profit target)
40% of your $6,000 profit target = $2,400. That means no single day can exceed $2,400 in profit. If a day exceeds this, your effective profit target increases.
A) Profit target achieved ✅
Day | Profit |
Day 1 | +$2,000 |
Day 2 | +$2,000 |
Day 3 | +$2,000 |
Total profit: $6,000 (target reached)
Best Day: $2,000 → Valid (below $2,400 cap)
Note: No day exceeds 40% of the target, so the $6,000 target is fully valid — challenge passed.
Also valid — right at the limit:
Day | Profit |
Day 1 | +$2,400 |
Day 2 | +$2,400 |
Day 3 | +$1,200 |
Total profit: $6,000
Best Day: $2,400 → Valid (exactly at the 40% cap)
B) Profit target increases ❌
Day | Profit |
Day 1 | +$2,500 (Best Day) |
Day 2 | +$2,000 |
Day 3 | +$1,500 |
Total profit: $6,000 (nominally hits the target)
Best Day: $2,500 → Invalid (exceeds $2,400 cap)
Note: Because the Best Day exceeds 40% of $6,000, the profit target increases. The new effective target becomes $2,500 ÷ 0.40 = $6,250. The trader needs to keep trading without beating the $2,500 Best Day until Total Profit reaches $6,250 for the target to actually count.
How to use the Dashboard to your advantage
Remember that you can always rely on your Dashboard data
Go to your dashboard, check your payout overview, and hover over the (i) icon in the best day rule section, and you will be able to check:
1. What is the total amount of profits your account must reach.
2. How much is remaining to fulfill the best day rule.
Intentionally attempting to bypass the Best Day Rule by splitting a large winning position through hedging or partial closures is not allowed and may result in all profit from that position being consolidated into a single day.
Example: Partially closing a large winning position across multiple days. It may be viewed as an attempt to bypass the rule, especially if the profit is generated during a single-day market movement.
Example: Opening several positions on a given instrument on one day and closing them across multiple days. Such positions may be considered a single trade idea. It may be viewed as an attempt to bypass the rule, especially if the trade idea capitalizes on a single-day market movement.
Example: Immediate opening, closing and re-opening a position held across multiple days. It may be viewed as an attempt to bypass the rule because such positions are considered a single trade idea with identical market exposure.
