What is a trailing drawdown, and how does it move as you trade?

A trailing drawdown is a loss limit that moves. Instead of sitting at a fixed level for the life of the account, it follows your highest balance upward, keeping a constant distance beneath it, so a run of winning days lifts the floor along with the account. At Phoenix Trader Funding every evaluation uses one, it is measured at the end of the day rather than tick by tick, and it stops moving for good once it reaches your starting balance.

That last clause is the part most traders miss, and it is the difference between a limit that chases you forever and one that eventually turns into a fixed floor underneath your own money.

How the floor follows your balance

The number the drawdown trails is your high-water mark. A high-water mark is the highest balance the account has ever reached, not the balance it holds today. Once the account sets a new high, that high is permanent for the purpose of this calculation, and the loss limit sits a set distance below it.

Two consequences follow from that, and they surprise people in opposite directions. The first is that profit you have already made does real work: every new high drags the floor up behind it, so the room you have to lose is measured from your best day rather than from where you started. The second is that giving profit back does not give the floor back. The limit does not follow the balance down again. It has already moved, and it stays where the high-water mark put it.

Why end of day is the part that matters

An end-of-day drawdown is one that is recalculated once, after the session closes, using the balance at the close rather than the highest price your position touched during the day. Every evaluation at Phoenix Trader Funding is measured this way.

The practical effect is that intraday movement does not move the floor. A position that runs deep into profit at midday and then comes back before the close does not set a new high-water mark on the way past, so it does not drag the limit up behind it. A trader who scalps in and out all session is measured on where the day finished, not on the best moment inside it. If you trade actively inside the session, this is the single most useful thing to understand about how the limit behaves.

The drawdown stops at your starting balance

The trailing stops. Once the account has made enough profit that the rising floor reaches the balance you started with, the floor freezes there and never adjusts again. From that point the limit is static, sitting at your starting balance, and it stays there for the rest of the account's life however high the balance climbs afterwards.

This is worth stating plainly because the alternative design, a limit that trails all the way up forever, is common in this industry and behaves very differently. Under a limit that never stops, a profitable account is permanently working against a floor that keeps closing in from below. Under one that stops at the starting balance, there is a point where the trailing phase is simply over.

Trailing is not the only kind, and not every account uses it

A static drawdown is the other kind: a loss limit fixed at one level from the first trade, which does not move at all no matter what the balance does. Naming the account type matters here, because the lineup does not behave uniformly.

• In the evaluation stage, every account family uses an end-of-day trailing drawdown, with one exception below.
• A funded Classic account keeps the end-of-day measurement it had during the evaluation.
• The Daily family keeps end-of-day measurement through the challenge and through the funded account, which is one of that family's headline points.
• A funded Spark account trails in real time, intraday, rather than at the close. This is a genuine difference from Classic and Daily, and it is the one most worth checking before you change platforms or strategies.
• A Merit evaluation has no trailing drawdown at all. It uses a static total loss limit instead.
• On Live funded accounts the drawdown type is static across the whole lineup, and it stops adjusting at the starting balance.

Because of that spread, a claim like "the drawdown here is end of day" is only ever true of a named account type at a named stage. It is not true of the lineup as a whole.

A daily loss limit is a separate rule

A daily drawdown is a cap on what a single day can lose, reset each session, and it sits alongside the trailing drawdown rather than replacing it. The two are independent, and traders often conflate them.

Classic, Daily and Spark accounts carry no daily drawdown at all, in the evaluation or once funded. Merit is the exception: it carries a dynamic daily limit of 25 percent. On Live funded accounts the daily limit is scalable and is set with the trader rather than fixed in advance, and a Merit Live account carries no daily limit, no safety net and no consistency requirement.

What to check before you trade

Three questions settle how the limit will behave on any given account. Which stage are you in, evaluation or funded. Which family is it, because Spark measures differently from Classic and Daily once funded. And has the floor already reached your starting balance, because if it has, the trailing phase is finished and you are trading against a static number.

Funded Classic and Daily accounts also carry a locked safety net, which funded Spark and Merit accounts do not. That is a separate mechanic from the drawdown and it is worth reading on its own terms. If you want the mechanics either side of this one, see what a breached account means and what follows and how payouts work on a funded account. The full rule set for each account family is published on the Phoenix Trader Funding site.

Common follow-up questions

Does a trailing drawdown ever move back down?

No. A trailing drawdown follows the high-water mark, which is the highest balance the account has ever reached, so it only ever moves upward. Losing money after a new high leaves the floor exactly where the high put it.

What is the difference between a trailing drawdown and a static one?

A static drawdown is fixed at one level from the first trade and never moves. A trailing drawdown starts below your opening balance and climbs with each new high-water mark, until it reaches your starting balance and freezes there permanently.

Does the drawdown keep trailing once the account is funded?

It depends on the family, so check the account type rather than assuming. A funded Classic keeps end-of-day measurement, the Daily family keeps end of day through both the challenge and the funded account, and a funded Spark trails in real time intraday.

Is there a daily loss limit on top of the trailing drawdown?

Not on Classic, Daily or Spark accounts, which carry no daily drawdown in the evaluation or once funded. Merit is the exception and carries a dynamic daily limit of 25 percent. Live accounts use a scalable daily limit set with the trader.

Why does end-of-day measurement matter if you trade inside the session?

Because the floor is recalculated once after the close rather than continuously. A position that runs into profit at midday and gives it back before the close never sets a new high-water mark, so intraday swings do not drag the limit up behind them.
