The daily loss limit ends more funded accounts than the overall drawdown does, because it can be breached on an ordinary day rather than a bad month. It is also the rule traders are least sure about, since firms measure it from different starting points and a few include open positions.
This gives the number that actually matters during the session: how much is left before the account is gone, and the largest position that fits inside it given the stop you intend to use. When the room is smaller than one normal trade, the answer is to stop for the day, and the calculator says so.
When to use it
- Mid-session, after a loss, before deciding whether to take another trade.
- At the start of the day, to fix the maximum size for the session.
- When a firm measures from equity and an open position is moving against you.
- When comparing two firms with the same headline percentage but different measurement.
The limit is a percentage of either the day’s starting balance or the original account size.
Limit = Basis × Daily Rule %
Room Left = Limit − Lost So Far
Floor = Start Of Day Balance − Room Left
Max Lots = Room ÷ (Stop × Pip Value)- From the day’s starting balance means the limit moves with the account, so a profitable week raises it. From the initial size means it never moves. The second is stricter after a drawdown and looser after profit.
- Many firms measure equity, not balance, so an open position in loss counts against the limit before it is closed. If yours does, subtract floating losses too.
- The day rolls over at the firm’s server time, which is often not your midnight. A trade held across that boundary is measured against the new day.
- The largest position shown assumes a full stop loss on one trade with nothing else open. Two trades at that size cannot both be wrong.
A $100,000 account with a 5% daily limit measured from the day’s starting balance of $103,000, already down $1,800, with a 25 pip stop on EUR/USD.
Working: five percent of $103,000 is $5,150 for the day. Having lost $1,800, there is $3,350 left. A 25 pip stop on EUR/USD costs $250 per lot, so the room covers 13.4 lots — but a position that size uses the entire day in one trade, which is exactly how accounts are lost.
Is the limit measured from balance or equity?
It depends on the firm, and it is the detail worth checking before anything else. Balance ignores open trades until they close; equity counts a floating loss immediately, so a position moving against you can breach the rule while it is still open.
Does the limit reset from my new balance each day?
At most firms yes, which is what the first option models. Some firms fix it to the starting account size forever, which is harsher after a drawdown because the limit stops shrinking with the account but the account has less room above the floor.
What time does the day roll over?
The firm’s server time, usually a broker platform time rather than your own. It is commonly 5pm New York, which is midnight or later in South Asia, so a trade left open in the evening can land in the wrong day.
Should I really trade the largest position shown?
No. That figure is the ceiling, not a recommendation — it uses the whole day on one trade. It is shown so you can see how far away the ceiling is, and most traders should stay well under a third of it.
