Daily Loss Limit
Drawdown & Loss LimitsThe maximum amount you can lose in a single trading day before your account is flagged or terminated. This resets each day and is separate from your overall maximum drawdown.
The daily loss limit prevents catastrophic single-day blowouts. Most firms set it between 2% and 5% of the account balance. It acts as a circuit breaker -- even if overall drawdown has room, exceeding the daily limit triggers an immediate violation.
Daily loss limits can be calculated from starting daily balance or from equity. Balance-based means the limit is based on your account balance at the start of the day. Equity-based means open unrealized losses count toward the limit. Equity-based is stricter because a large floating loss can trigger the limit even if you haven't closed any trades.
Notably, Apex Trader Funding has no daily loss limit during evaluation -- they rely solely on the trailing drawdown. This gives traders more flexibility on volatile days but means one bad day can wipe out all your drawdown room.
On FTMO $100K with 5% daily loss limit: you can lose up to $5,000 in a single day. If you start the day at $108,000 balance, your daily limit is $5,000 (from starting balance). Your equity cannot drop below $103,000 that day. If it does, even briefly, your account is violated.
Daily Loss Limit directly affects whether you pass or fail a prop firm evaluation. Unlike trading your own account where you can recover from mistakes over time, prop firm rules create hard boundaries -- violate them once and you lose your challenge fee and have to start over. Drawdown rules are the number one reason traders fail prop firm evaluations. Understanding exactly how daily loss limit works at your chosen firm is not optional -- it is the foundation of every position sizing decision you make.
Practical example across firms: FTMO and TopStep handle this differently. FTMO is a 2-step firm with static drawdown and a 5% daily loss limit, starting from €155. TopStep is a 1-step firm with trailing drawdown and a 2% daily loss limit, starting from $49. These structural differences mean your approach to daily loss limit must adapt to whichever firm you choose.
Common mistake: Traders often assume all drawdown rules work the same way. They do not. The difference between static and trailing drawdown can mean the difference between surviving a losing streak and losing your account while still net profitable. Before starting any evaluation, calculate exactly how much room you have in dollar terms, not just percentages.
Static Drawdown
A fixed maximum loss threshold set at account opening that never moves, regardless of how much profit you accumulate. Your drawdown floor stays at the same level for the lifetime of the account.
Trailing Drawdown
A maximum loss threshold that moves upward as your account reaches new equity highs. Unlike static drawdown, the floor rises with profits, meaning gains raise the minimum balance you must maintain.
Equity-Based Drawdown
A drawdown calculation method that includes unrealized (open) trade profits and losses in the account value. Your equity fluctuates with every tick while positions are open, making this stricter than balance-based drawdown.
Balance-Based Drawdown
A drawdown calculation method that only considers closed trade results, ignoring unrealized profits and losses from open positions. Your balance only changes when trades are closed.
Risk Per Trade
The maximum dollar amount or percentage of account balance you are willing to lose on a single trade. Most prop firm traders risk 0.5-2% per trade to ensure they can withstand losing streaks without breaching drawdown limits.
