Static drawdown: measured from initial balance, never changes. $100K account with 10% static DD = floor at $90K, regardless of how high equity goes. Trailing drawdown: the floor moves up with equity. If your $100K account reaches $105K, your trailing DD floor moves from $90K to $95K. Trailing DD is stricter because profits partially lock in. FundedNext uses trailing DD in some plans; FTMO uses static DD.
