TL;DR: pick your firm and account size (or enter your own numbers) and see your live breach level, how much room you have right now, and whether your drawdown has locked at the starting balance. Presets are common published defaults — firms change rules by plan and promo, so verify yours in the firm's official documentation.
Trailing drawdown follows your account's balance peak: breach level = peak − drawdown, until the peak clears the starting balance + drawdown — at that point most firms lock the level at the starting balance (the "breakeven lock"). Intraday trailing moves with every unrealized high-water mark; end-of-day trailing only advances at the daily close; static drawdown never moves from start − drawdown. This calculator uses the same model as Trading Floor's live drawdown guardian, which auto-flattens your account at a cushion you set above the firm's line.

A trailing drawdown is a maximum-loss line that follows your account's balance peak upward: breach level = peak balance minus the drawdown amount. If your balance touches that line, the account is breached. On most firms the line stops trailing (locks at the starting balance) once your peak clears the starting balance plus the drawdown amount.
Intraday trailing follows every unrealized high-water mark — a winning trade that runs and pulls back raises your breach level even if you exit flat. End-of-day trailing only advances at the daily close, so intraday spikes don't move the line. Apex and Topstep use intraday-style trailing; MyFundedFutures and Take Profit Trader use end-of-day. Always verify your plan's rules with the firm.
On most firms the drawdown locks at your starting balance once your peak balance reaches the starting balance plus the full drawdown amount — after that, breaching means falling back to breakeven, not further.
It can lower the risk, not remove it. Trading Floor's drawdown guardian tracks each account's live equity against this same model and auto-flattens the account at a configurable cushion above the firm's line, then stops copying to it. It checks every few seconds, not every tick, so a fast market can still reach the line first. One click applies your firm's preset; every other account on the floor keeps running.
Trading Floor checks every account's drawdown every few seconds and flattens at the cushion you set. 7-day free trial.
