Guides / Trailing vs. Static Drawdown
GUIDETrailing vs. static drawdown: not the same rule.
Two funded accounts can both advertise a "10% max drawdown" and still be enforcing completely different limits. Here's the difference, a worked example, and how to size for the floor you're actually on.
Quick answer: a static drawdown limit is fixed against your starting balance and never moves. A trailing drawdown limit rises every time your account hits a new equity high — and on most prop firms, it doesn't come back down when equity dips. Trailing rules are almost always stricter than they sound, because the floor keeps chasing your best moment, not your starting one.
Why "drawdown" means two different things
A static (sometimes called "absolute") max drawdown is measured from your account's starting balance and stays put. A $100,000 account with a 10% static rule has a floor at $90,000, full stop — it doesn't matter if equity has climbed to $130,000 in the meantime.
A trailing max drawdown is measured from your account's highest-ever equity, and that high-water mark keeps moving up as you make money. The floor isn't 10% below where you started — it's 10% below the best you've ever done, and on most firms it never resets lower once it's ratcheted up.
A worked example
Take a $100,000 account with a 10% drawdown rule under both interpretations:
- Static: the floor is $90,000 on day one and stays $90,000 for the life of the account, regardless of how high equity ever climbs.
- Trailing: the floor starts at $90,000 too — but the moment equity touches a new high of, say, $104,000, the floor ratchets up to $93,600. Give back that gain and a chunk more, and you're breached, even though you're still up overall from where you started.
Same starting balance, same "10%", same account size — a meaningfully tighter real-world buffer once the account has any winning streak behind it.
Why the intraday version is stricter still
Some firms calculate the trailing high-water mark from closed-trade balance only, checked end of day. Others calculate it from floating equity, checked continuously — meaning an open position that briefly swings deep into profit can set a new high-water mark even if you close that same trade at breakeven. You can end a day flat or slightly green and still have moved your own floor higher without realizing it.
Where traders misjudge trailing rules
- Assuming "10% drawdown" means the same dollar buffer as a static account, and sizing accordingly.
- Assuming the floor resets downward after a losing stretch — on a trailing rule, it typically doesn't.
- Not confirming whether the firm's trailing calculation uses balance (closed trades) or equity (including floating P&L).
- Sizing every funded account the same way regardless of which rule it runs, instead of treating the trailing floor as the binding constraint.
What to actually do about it
Read the exact rule document for each account — balance or equity basis, end-of-day or intraday, and whether the trail ever stops moving once you hit a target. Then size against the tightest realistic version of that floor, not the average one, and track the floor live rather than doing the ratchet math by hand every time you make a new high.
