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 trailing drawdown actually is
Every funded futures account has a maximum loss limit — a floor your equity can't touch without breaching the account. What makes trailing drawdown dangerous is the word trailing: as your balance climbs, the floor climbs with it, dollar for dollar. Make $3,000 and on most intraday accounts your floor rises $3,000 too. Give that $3,000 back on a bad afternoon and you can breach an account you started the session even on — you haven't lost a penny of your starting capital, but the account is gone.
This is the mechanic that catches even experienced traders. The math is simple once you see it; the problem is most people don't check their floor before sizing into a big trade.
Intraday vs end-of-day — the distinction that decides everything
Intraday trailing — used by Apex Intraday, Topstep, and Take Profit Trader funded — follows your highest unrealized equity tick by tick. If you spike $5,000 on an open trade at 9:45 AM, your floor moves up $5,000 in real time, even though you haven't closed a single position. If that trade reverses and you exit flat, your closed balance is unchanged — but your floor is $5,000 higher than it was before the trade. That gap is the silent kill zone.
End-of-day trailing — Apex EOD, Tradeify, Alpha Futures — only recalculates the floor after the trading session closes, and only on your closed balance. Intraday equity spikes, no matter how large, leave the floor untouched until you lock them in. This is a fundamentally different risk profile. Two traders on the same firm, one intraday and one EOD, can make identical trades and have completely different floor movements.
The most common preventable blowup in funded trading: a trader assumes EOD behavior, takes a big morning spike, lets the trade run, gives it back, and checks their floor after the fact.
Where the floor stops trailing (the lock)
Most firms stop the trailing mechanic once you've banked enough profit. The floor freezes — called the lock — and from that point it no longer rises with your balance. Specific lock points:
- Apex Trader Funding: floor locks $100 above your starting balance (so for a $150K account, at $150,100).
- Topstep funded: floor locks at your exact starting balance — once you're above water, the floor never rises again.
- TradeDay: floor is static from day one — it never trails at all on the funded account.
- Tradeify / Earn2Trade: trailing until the starting balance is reached, then locks.
Until the lock is hit, every dollar of profit you give back is a dollar closer to a breach. The pre-lock phase is the highest-risk period of any funded account.
How to calculate your current floor
The formula: floor = peak equity — allowed drawdown. For an Apex $150K intraday account with a $5,500 drawdown, if your peak equity (including any unrealized highs) reached $158,000, your current floor is $152,500. Your headroom is your current balance minus $152,500. On intraday accounts, peak equity updates every second the market is open.
This is why eyeballing it is dangerous — you need the exact number, updated continuously, and sized to it before entering a trade.
How to stop losing accounts to trailing drawdown
Three rules that eliminate most trailing-drawdown blowups:
- Know your floor before every trade, not after. Your position size should be set so that a normal adverse move cannot reach the floor.
- On intraday accounts, treat unrealized equity as real. A $4,000 open gain has moved your floor $4,000. Size your risk from your new, higher floor — not your starting balance.
- Stop for the day before you give back a session's gains. One of the most common patterns in funded account failures: a strong morning, a deteriorating afternoon, and a breach at 3 PM on a session that was +$2,000 at its peak.
FundedStreak tracks all of this automatically. It knows your firm's exact mechanic, whether your account is intraday or EOD, where your floor currently sits, and updates your live headroom and safe contract size in real time. The 60/80/90% alerts fire before you breach — not after.

What is trailing drawdown in prop trading?
Trailing drawdown is the maximum loss limit on a funded futures account. Unlike a static drawdown, it rises as your account balance climbs — so if you make $3,000 and then give it back, the floor may breach even though you started the session flat.
What is the difference between intraday and end-of-day trailing drawdown?
Intraday trailing (used by Apex Intraday, Topstep, and Take Profit Trader) moves your floor with every tick of unrealized equity — including open positions. End-of-day trailing (Apex EOD, Tradeify, Alpha Futures) only adjusts the floor at session close based on closed P&L. A trader who assumes EOD behavior on an intraday account is the most common cause of preventable blowups.
When does the trailing drawdown floor stop moving?
Most firms lock the trailing floor once your account reaches a specific profit target. Apex locks the floor at $100 above your starting balance. Topstep funded accounts lock at your starting balance. TradeDay locks the floor at the start of the funded account. Until that lock is hit, every dollar of open profit that you give back also moves the floor closer to your current balance.
Does a big winning trade move the trailing drawdown floor?
On intraday trailing accounts (Apex Intraday, Topstep), yes — even unrealized equity moves the floor. If you are up $5,000 intraday on an open trade, the floor rises by $5,000. If the trade reverses and you exit flat, your floor is now $5,000 higher than before the trade, even though your closed balance didn't change. On end-of-day trailing accounts, an open trade does not move the floor until after the session close.
How do I calculate my trailing drawdown floor?
Your trailing floor = peak equity reached minus the allowed drawdown amount. For an Apex $150K intraday account with a $5,500 drawdown, if your peak equity was $158,000, your floor is $152,500. Use the free FundedStreak drawdown calculator to get the exact number for your account.
Which prop firms use intraday trailing drawdown?
Apex Trader Funding (Intraday variant), Topstep, and Take Profit Trader funded accounts all use intraday trailing drawdown. MyFundedFutures Rapid accounts also use intraday trailing. The intraday mechanic is more aggressive because unrealized equity moves the floor.
Which prop firms use end-of-day trailing drawdown?
Apex EOD accounts, Tradeify, Alpha Futures, MyFundedFutures Pro accounts, and Earn2Trade use end-of-day trailing. The floor only adjusts after the session closes, so intraday equity spikes do not move it.
