More funded accounts are lost to a misunderstood drawdown rule than to bad trades. Two traders can make the identical sequence of trades and one passes while the other breaches — purely because of how their firm calculates the loss limit.
Here are the three drawdown types you'll meet, worked through with numbers, plus the mistakes that quietly blow accounts.
Mechanics differ by firm and by account type. Treat the examples below as the general logic, and confirm the exact rule for your specific account before you trade it.
The three drawdown types
1. Static (absolute) drawdown
The simplest. A fixed loss floor is set from your starting balance and never moves. On a $50,000 account with a $2,000 static limit, your floor is $48,000 — full stop. Profits don't change it; drawdowns don't change it. As long as your balance stays above $48,000, you're fine.
This is the most forgiving type because once you bank profit, that profit is a cushion the limit can't reach.
2. End-of-day (EOD) trailing drawdown
The floor trails your profit, but only updates once a day based on your end-of-day balance. Intraday swings don't move it; it ratchets up when you close the day higher.
Same $50,000 account, $2,000 trailing limit. Start: floor = $48,000. You finish day one up $1,000 at $51,000 → at the next day's open the floor trails up to $49,000. If during day two your balance wicks around intraday, the floor doesn't budge — it only re-evaluates at the day's close. More demanding than static, but predictable, because you always know your floor at the start of each session.
3. Intraday (real-time) trailing drawdown
The strictest, and the one that catches people. The floor trails your highest intraday equity in real time — including unrealized peaks. The moment your equity prints a new high, the floor moves up to match and never comes back down.
Same $50,000 account, $2,000 limit. Floor starts at $48,000. You take a trade that runs to +$1,500 unrealized (equity $51,500) before you close it for +$300. Your realized gain is only $300 — but the floor already trailed to $49,500, because it followed the intraday peak. You're now in profit and yet only $800 of room separates you from a breach. A normal pullback can end the account while your P&L is still green.
Many firms stop the trail once the account reaches its starting balance plus the drawdown amount, then lock the floor (often at the initial balance). Others trail indefinitely. This single detail changes everything — verify it.
The mistakes that blow accounts
- Not knowing which type you have. This is the number-one error. The same trades pass under static and breach under intraday trailing. Read the rule before the first trade, not after the breach.
- Letting a winner run, then giving it back. Under intraday trailing, every new equity peak permanently raises your floor. A round-trip from +$1,500 to +$300 doesn't just cost you $1,200 of profit — it moved your floor up $1,500. Banking partial profit and protecting peaks matters more here than anywhere.
- Confusing balance with equity. Intraday trailing usually tracks equity, which includes open-position P&L. Your floor can move on a trade you haven't even closed.
- Forgetting whether the trail locks. Whether the floor freezes at your starting balance after a buffer — or keeps trailing forever — decides how much breathing room you ever get. Don't assume; confirm.
- Sizing for the target instead of the floor. Position size should be set by how far you are from your drawdown floor, not by how fast you want to hit the profit target.
How to keep the limit in front of you
The breach almost always happens because the floor is invisible in the moment — you're watching price, not your trailing limit. The fix is to keep the number on the chart.
Forge Pro includes a prop-firm stats section built for exactly this: you enter your account size, contracts, profit target, drawdown limit, and drawdown type, and it tracks PnL, days, and a challenge-style summary against those constraints on your chart — so your distance to the floor is always visible, not something you reconstruct after the fact.
And before you ever fund an account, the drawdown rule should be part of how you choose the firm in the first place. PropScorer compares prop firms on exactly these terms — drawdown type, limits, and the conditions that decide whether a given style can realistically pass.

FAQ
What is trailing drawdown? A loss limit that follows your account's profit peak upward. As your balance or equity makes new highs, the floor rises with it and never moves back down — so giving back gains can breach the limit even while you're still in profit.
Which drawdown type is hardest to pass? Intraday (real-time) trailing is generally the most demanding, because it trails your highest intraday equity, including unrealized peaks. A trade that runs deep into profit and is then given back can raise your floor permanently. Always confirm the exact rule with your firm.
