Best-day rule – 40 %, but it never kills the account

score = (Best Day ÷ Total Profit) × 100  →  must be ≤ 40 %

Day profit is measured on realized results: positions (or parts of positions) closed during the Day, plus Swap and Commission charged that Day (D.19). In the Challenge the rule is measured in each Phase separately (D.20).

If a single Day makes up more than 40 % of your profit, you do not fail. Your target goes up.

new target = Best Day ÷ 0.40

Example: 100k account, target 8,000 USD. You make 5,000 in one Day → the target rises to 12,500 USD. You keep trading, nothing is forfeited, the account lives.

On the Funded Account it is the gate to payout. It is measured from the last successful payout (for the first one, from the day the account was issued): as long as the Best Day of that period makes up more than 40 % of the same period's profit, you cannot request a payout. You keep trading until the ratio comes down – nothing is deleted, nothing is forfeited, the payout is only postponed until you meet the condition. After every successful payout the counter resets and starts over.
