Does the daily loss limit include open trades?

On most funded accounts, yes. An open position sitting at minus 500 counts against your daily loss limit while it's still open, and plenty of accounts are closed out before the trader ever clicks sell.

If your limit is measured on equity, the market decides when you breach it. If it's measured on closed balance, you decide.

The arithmetic

A 50,000 account with a 1,000 daily loss limit. The day starts at 50,000, so the line sits at 49,000.

You take two losers for 600 total. Your balance is 49,400 and you still have 400 of room on paper. Then a third trade goes 500 against you and you're holding it, waiting for the retest.

On the equity-based account the breach happened while you were still deciding. Nobody asked you. On the balance-based account you have 400 left and a choice to make.

That 500 was never a loss you agreed to take. It was a number on a screen that the rulebook treated as real.

The three things that change the number

1. Equity or closed balance. Equity counts floating positions. Closed balance counts only settled trades. The first is far more common on evaluation accounts, and it's the one that ends days early.

2. Measured from what? Most programs measure from the balance at the start of the day. Some measure from the highest equity point reached during that day. The difference is brutal when you're up early: with a start-of-day reference, being up 500 gives you 1,500 of room before the line. With a high-water reference, that same 500 gain moves the line up with you, and a 1,000 round trip from the high breaches it while you're still green on the day.

3. When does the day end? The reset time is the firm's, not yours. If the day rolls over at 5pm New York and you're holding a position through it, the position doesn't reset. Your loss counter does, and the trade carries its open loss into the new day's count from the first second.

What this means for position size

Your real daily budget is the limit minus whatever your open trades can move against you before you'd get out.

Say the limit is 1,000 and your stop on the current trade is 400 away. While that trade is open, your effective budget for everything else is 600, not 1,000. Traders who size from the headline number are borrowing against room that's already committed.

The habit that fixes it: before entering, subtract the full stop distance of every open position from your remaining daily room. If what's left is smaller than the next trade's risk, the next trade doesn't happen. That's a rule you can check in four seconds.

Where it goes wrong quietly

The pattern that ends most days is the small loss you refuse to close.

Two clean stops for 300 each leave you at 400 of room, which is uncomfortable but fine. A third trade at minus 500, held because closing it would make the day final, puts you at 48,900 on an equity account. The rulebook does the closing for you, and the position that ends your day is the one you were trying to save.

If you keep a journal, this shows up as a specific and countable thing: trades where the maximum adverse excursion went well past your planned stop. Sort your last fifty by that field. If more than a handful ran past the stop, your working limit is 1,000 minus however far you tend to let things run.

Read your own rules, then check your log

Three questions, answerable in five minutes from the agreement:

• Does the limit read equity or closed balance?
• Is it measured from the start-of-day balance or from the day's high?
• What time does the day reset, in which time zone?

Then two numbers from your own journal: your average loss compared with your planned risk, and how often an open position went past the stop. The rules tell you where the line is. Your log tells you how close you actually trade to it.

The same equity-versus-balance question decides your trailing drawdown, and the answer isn't always the same for both rules in the same agreement. We worked through that one in does trailing drawdown include unrealized profit, and you can pressure-test your own numbers with the trailing drawdown check.

Short version

Assume open trades count until your agreement says otherwise. Size from the limit minus the stop distance of everything already open, know whether the day is measured from your starting balance or your high, and know what time the day ends. Then look at your log to see how much of that room you've been spending without noticing.
