Yes. You can breach your account even if you are still in overall profit.
Your daily drawdown limit is calculated from your account equity at the start of each trading day, rather than from your initial account balance or deposit.
For example:
You start with $10,000.
You finish the day at $10,500.
The next day, your daily drawdown floor is $10,080, based on a 4% daily drawdown from $10,500.
If your equity falls to $10,050, you breach the daily drawdown limit.
This means you can breach the account even if your equity is still above your original $10,000 starting balance or you have a trade that is currently in profit.
Always monitor your daily drawdown level based on your current trading day's starting equity.
Please note: The 50% consistency rule is not a breach rule. If a single trading day makes up more than 50% of your total profit, your pass or payout is simply put on hold until you make enough profit on other days to meet the consistency requirement. Nothing you've earned is lost.
