Understanding the max daily loss rule
The maximum daily loss limit is one of the two core drawdown rules on every prop firm account (alongside the overall drawdown limit). It caps how much you can lose in a single trading day before the account is locked or terminated. Typical limits range from 1% to 5% of the account balance, depending on the firm and account type.
How the daily loss is calculated
Most firms calculate the daily loss from your balance at the start of the day (or from the prior day's close). This means if you made $500 yesterday and start today with a higher balance, your daily limit is calculated from the new, higher balance. Some firms calculate from the equity at market open, which can include unrealised profits or losses from overnight positions.
This distinction matters if you hold positions overnight. An open position with a floating loss that exceeds your daily limit at market open could immediately trigger a breach before you have placed a single new trade. Always check whether your firm calculates the daily limit from balance or equity.
When the daily limit resets
Daily loss limits reset at a specific time — usually midnight Eastern Time (ET) for most US-based prop firms, or midnight Central European Time (CET) for European firms. Some firms use midnight UTC. The reset time is critical if you trade across time zones or during the overnight session.
A common mistake is assuming the daily limit resets at midnight in your local time zone when it actually resets at midnight ET. If you are in London, that is 5 AM your time — meaning what feels like a “new day” of trading at 8 AM London time is actually 7 hours into the firm's trading day. Any losses from 5 AM to midnight London time are part of the same “day” from the firm's perspective.
How to structure your risk within the daily limit
The daily loss limit should act as an absolute floor, not a daily risk budget. Most experienced funded traders aim to risk no more than 50% of the daily limit across all trades in a session. For example, on a $100,000 account with a $2,000 daily limit, they would plan to stop trading if losses reach $1,000 — well before the firm's limit is hit.
This personal limit creates a buffer that allows for spread costs, slippage, and unexpected market moves without the pressure of being right up against the firm's hard limit. If you consistently use 90%+ of your daily limit before stopping, you are trading too close to the edge.
Maximum trades per day given your risk limits
If your daily limit is $2,000 and you risk $400 per trade (a 0.4% risk on a $100,000 account), you can afford a maximum of 5 consecutive losing trades before hitting the daily limit. In practice, this means a losing streak of 5 trades forces you to stop for the day. Most traders find this to be a reasonable discipline: if you have lost 5 trades in a row, the session conditions are likely unfavourable and stepping away is the correct decision regardless of the limit.
Always confirm your firm's exact daily loss calculation method and reset time in their official rules or support documentation.
