A static drawdown is a prop firm loss limit fixed at your starting balance that never moves, no matter how much profit you make. On a $100,000 account with 10% static drawdown, your equity floor is $90,000 on day one and $90,000-equivalent forever (rising only if the firm's scaling plan raises the balance itself).
It is the most predictable of the drawdown types and the friendliest to swing-style traders: profits you bank never come back to haunt you as a tighter floor. The trade-off is that firms offering static limits usually pair them with lower account sizes or stricter daily limits, because the firm carries more tail risk.
Worked example: you run to $125,000, then give back $30,000. Under a static 10% you are fine - the floor stayed at $90,000 and you are at $95,000. Under a 10% trailing floor locked at your peak, you breached at $112,500.
The head-to-head: static vs trailing drawdown; where futures firms land on this: static drawdown in futures.
