End-of-day or intraday drawdown: what it changes for a prop firm challenge

An evaluation account almost always shows a maximum drawdown, $2,000 on a $50,000 account for instance. That figure alone says little: you need to know what it is measured from. The loss threshold, the balance below which the account is lost, starts at the starting capital minus that drawdown. On most prop firm accounts, it then moves up as the account grows: that is a “trailing” drawdown.

The whole difference lies in when it moves up. At the end of the day (EOD), the threshold is recalculated once, at the close, on the day’s balance. In real time (intraday), it follows the highest value the account reaches during the session, open profits included. There are also static thresholds, which never move, and the same firm sometimes sells two variants of the same account.

Take a $50,000 account with a $2,000 drawdown, and a single trade in the day. It runs up to $800 of open profit, then comes back; you exit on a stop moved up, at +$100.

With a static threshold, it stays at $48,000 and you have $2,100 of room. At the end of the day, the account closes at $50,100 and the threshold moves to $48,100: $2,000 of room, as at the start. In real time, the threshold followed the high, $50,800, and stopped at $48,800: you have only $1,300 left. The profit handed back to the market came out of your room, even though the day ends positive.

During my challenge, I took an Apex 50K evaluation with a $2,000 drawdown recalculated at the end of the day. The table shows the balance and threshold read on Apex at the end of each session. On the days the balance makes a new closing high, the threshold moves up and the room goes back to $2,000.

On October 1, the day ends with a loss of $1,005.02. The threshold does not come down: it stays at $50,284.76, the previous day’s, and I finish $994.98 above it. That is the one-way nature of a trailing drawdown: it goes up, it never comes back down. The day after a loss, you trade with less room.

That morning, my first Nasdaq short, 8 MNQ, shows $544 of open profit on the capture, before I exit at +$439.68 on a stop moved up early. On my EOD account, those $544 changed nothing to the threshold during the session. On an intraday account, the threshold would have moved up by at least $544 at that moment, and it would never have come back down.

With the same balances, the end-of-day room would therefore have dropped to $451 at most, instead of $994.98. No exact figure: I did not record the highest open profit of each position, and that is precisely what you would need to track on this kind of account.

In real time, what counts is the highest point reached, not the exit price. Letting a profit run only to hand it back costs room even when the trade ends positive. A target decided before the entry and partial exits weigh more there than on an EOD account. And the risk per trade is computed on the room you have left, not on the starting $2,000.

At the end of the day, the session has more breathing space: open profit handed back costs nothing until the day is closed. But the threshold, even if it only moves up at the close, is usually monitored during the session: an open loss that touches it is enough to lose the account. Either way, check your room before you open the platform. The trading journal computes it for all three threshold types, and the calculator turns what is left into a number of contracts. The details (threshold locked at the starting capital, monitoring during the session) differ from one firm and one offer to the next: read them on the firm’s site.

FTS Liquidity Sweep Pro spots liquidity sweeps and shows its signals: on October 1, there were several during the morning, on the Nasdaq and on gold. It knows nothing about your account, neither the drawdown type nor the room left. How many signals I take in a session, and at what size, is my decision, and it depends directly on that room.

That day, my mistake was taking a long more than an hour after its signal, without a real CISD (change in state of delivery), when the session had already cost me. On an intraday account, the same mistake would have weighed more. The rule I keep from it holds for both variants: a dented room cuts size and the number of trades; it never justifies adding one to win it back.
