What is EOD trailing drawdown?
A loss floor that follows your best end-of-day balance, then stops at your starting balance.
Your account fails if the balance falls to the floor. With an end-of-day (EOD) trailing drawdown, the floor sits a fixed amount below your highest closing balance, so it only moves up after a day closes higher.
Most firms stop moving the floor once it reaches the starting balance. After that, every profit above it is a buffer you keep.
Even with an EOD floor, most firms check it in real time, so an open trade that dips through today's floor still ends the account.
Example: On a $50K account with $2,000 EOD trailing: close day one at $50,800 and the floor rises from $48,000 to $48,800.
