Drawdown Anchor
Also known as: static drawdown, trailing drawdown, trailing max drawdown, drawdown type, max loss anchor
What is it?
A drawdown anchor is the reference point a prop firm measures your maximum drawdown from - either the fixed starting balance, or a high-water mark that rises as the account makes new equity highs. A static anchor is the simpler and more forgiving of the two. On a $100,000 account with a 10% static limit, the floor sits at $90,000 permanently, so profit gives you more room: the distance from your current equity down to $90,000 grows with every winning trade.
- 1The account opens at $100,000 Both anchors sit 10% below the starting balance. Static floor: $90,000. Trailing floor: $90,000. At this point they are identical.
- 2Equity climbs to $104,000 The static floor stays at $90,000, so the trader now has $14,000 of room. The trailing floor rises to $93,600, leaving $10,400 of room.
- 3Equity peaks at $108,000 The static floor is still $90,000, giving $18,000 of room. The trailing floor has climbed to $97,200, so the room has barely moved at $10,800.
- 4An $11,000 losing streak takes equity to $97,000 The static account survives with $7,000 to spare. The trailing account has crossed its $97,200 floor and is closed, despite never falling below its starting balance by more than $3,000.
A trailing anchor moves that floor up behind you. Reach $106,000 of equity and the floor rises to $95,400, so most of what you just made has become money you are no longer allowed to give back. The difference is decisive in practice.
Two traders both up $6,000 on a $100,000 account can absorb very different losing streaks: the static trader has $16,000 of room before breaching, the trailing trader has $10,600. Trailing anchors also differ in when they stop moving - some freeze once the account is up by the full drawdown amount, others trail indefinitely - and that clause matters more than the headline percentage does.
Why it matters: Whether your drawdown limit is fixed or trails your equity high decides how much of a winning run you are allowed to give back before the account is closed.
Static floor = Starting balance x (1 - max DD %); Trailing floor = Highest equity reached x (1 - max DD %)
A trailing anchor can close a profitable account after an ordinary retracement that a static anchor would have absorbed without incident.
Real-world example
A $100,000 account with a 10% trailing anchor peaks at $108,000, lifting its floor to $97,200. An $11,000 losing streak then breaches at $97,000, a level a static $90,000 floor would have absorbed.
How SignalBots handles it
SignalBots states each signal's stop distance before entry, so you can convert it into dollars and measure it against the distance from your current equity down to a trailing drawdown floor. See /risk-warning.
Pro tip
Recalculate a trailing floor after every new equity high rather than once a day - at many firms it moves the moment the high prints, including on unrealised profit.
Common pitfalls
Assuming a trailing anchor follows closed balance when the firm trails intraday equity, so a floating winner you never banked has already raised your floor.
Frequently asked questions
Which is better, a static or a trailing drawdown?
Static is more forgiving, because profit permanently increases your distance from the floor. Trailing anchors protect the firm during a winning run and usually come with a slightly higher percentage to compensate.
Does a trailing drawdown ever stop moving?
At many firms it freezes once the account has gained the full drawdown amount, locking the floor at the starting balance. Others trail indefinitely. This one clause changes the account's risk profile completely.
Is drawdown measured on balance or equity?
Most firms measure equity, so open floating losses count immediately and floating profit can raise a trailing floor. Assuming balance-based measurement is a common and expensive mistake.
How do I find my current drawdown floor?
Firm dashboards usually show remaining drawdown in dollars rather than the floor itself. Convert it: the floor equals current equity minus remaining drawdown, and recheck it after every new high.
Can a trailing anchor breach a profitable account?
Yes. If equity peaked well above the starting balance, the floor can sit above it, so an account still showing a gain from day one can breach after a retracement.
