What does Daily loss limit mean?
A daily loss limit restricts losses within the provider’s trading day. Its reference value, included costs, reset time and enforcement can differ from the total loss rule.
Example
A daily floor of $48,500 can be breached even if the total account floor is $47,000.
Illustrative example; not a provider’s quoted offer.Why it matters for prop traders
A new session may change the daily calculation while an overnight position remains open.
How do I read the rule correctly?
Identify the reference balance or equity, subtract the permitted loss amount, and determine what the firm monitors against that floor. Then check the session timezone, treatment of open positions and charges, and whether reaching the floor or only falling below it triggers a violation.
Why can a reset change the result?
Illustrative calculation: a daily reference of $50,500 minus a $1,500 allowance gives a $49,000 floor. If a later session uses a $51,000 reference, the same allowance gives a $49,500 floor. The account therefore needs a fresh calculation even if the trader still holds the same position. This is an example of one rule design, not a universal reset formula.
