Trailing drawdown explained: the mistake that blows funded accounts

Most funded accounts aren't lost to bad trades — they're lost to a trailing-drawdown floor the trader misjudged. Here's how it actually works.

What the trailing floor is

Every funded account has a maximum loss limit — a floor your balance can't touch. What makes it dangerous is that it trails: as your balance climbs, the floor climbs with it. Make $2,000, and on many firms your floor rises by $2,000 too. Give that profit back and you can breach an account you started flat.

Intraday vs end-of-day — this is the part people miss

Intraday trailing (Apex Intraday, Topstep, Take Profit Trader funded) follows your highest unrealized equity tick by tick. Spike $3,000 in the morning and the floor jumps — even if you never closed the trade. End-of-day trailing (Apex EOD, Tradeify, Alpha Futures) only recalculates at the session close on your closed balance, so intraday spikes don't move it. Same firm, totally different risk — and most blowups happen because a trader assumed EOD behavior on an intraday account.

Where the floor locks

The floor usually stops trailing once you've banked enough: Apex locks it $100 above your starting balance; Topstep's funded account locks at your starting balance; TradeDay freezes at the start. Until you reach that lock point, every dollar of profit you give back is a dollar closer to a breach.

How to stop losing accounts to it

Know your floor in dollars at all times, size so a normal losing streak can't reach it, and stop for the day before you give back the session's gains. FundedStreak does this automatically — it knows your firm's exact mechanic and shows your live headroom, safe size, and stop-out point.
