Know exactly where your account dies before you place a trade. Pick your firm or go custom — see your floor, your buffer, and your room in real time.
A trailing drawdown is a moving floor that rises with your account's high-water mark but never moves back down. Make money and the floor follows you up. Lose money and it stays put. Touch it and the account is gone — evaluation or funded, it doesn't matter.
This is the rule that ends most funded accounts. Not bad setups — math the trader never mapped. A $50K account with a $2,500 trailing drawdown starts with its floor at $47,500. Run the balance to $52,500 and the floor ratchets to $50,000: you've now locked in profit, but you also can't give back more than $2,500 from that peak without being liquidated.
End-of-day (EOD) trailing recalculates the floor once at market close, so intraday pullbacks on a winning trade don't count against you. Intraday trailing recalculates tick-by-tick on your unrealized equity peak — a single pullback on an open winner can breach you. Always confirm which your firm uses; it changes how much room you really have.
Many firms add a daily loss limit (DLL) that pauses trading for the session if hit but doesn't fail the account. It's there to stop the revenge-trade spiral. The trailing floor is the cliff; the DLL is the guardrail before it. The calculator shows both.
Preset firm numbers are approximate and change frequently — always verify the current rules with your firm before trading.
