The maximum amount of money you can lose in a single trading day before trading on your account is paused or the account is failed. Once this limit is reached, all open positions are typically closed automatically. Depending on the firm, hitting the daily loss limit can result in: pause”). ● Hard breach: The account is failed immediately, preventing further trading.
Why It Matters
- 1The daily loss limit is your most immediate risk management boundary.
- 2While Max drawdown tracks your overall account health, the daily loss limit prevents catastrophic single-day losses that could wipe out weeks of progress.
- 3Different firms set this at different levels — typically between 2% and 5% of account size — and how they calculate it (realized vs. unrealized, including commissions or not) can make a significant difference in your effective risk budget for each session.
Example
If you have a $100,000 account with a 4% daily loss limit ($4,000) and a trade loses $3,500, you only have $500 of loss capacity left for the day, and if the position drops another $600, the firm will automatically close all trades, resulting in either a soft breach (trading paused until the next day) or a hard breach (account failed), Your daily P&L resets at midnight or market open, depending on the firm.
Common Mistakes
- ✖Not accounting for commissions and fees when calculating remaining daily loss capacity
- ✖Averaging down on losing positions without tracking cumulative daily losses
- ✖Confusing daily loss limit with Max drawdown — they are separate rules that can both trigger account failure
