Max daily loss (MDL) in futures prop firms is a strict limit on how much a trader can lose within a single trading day. If the trader’s losses exceed this limit, the account typically fails the evaluation or is temporarily restricted to protect the firm’s capital.
Key Takeaways
- Max daily loss defines the maximum loss allowed during one trading session.
- Violating the limit usually results in evaluation reset or account restriction.
- MDL prevents large intraday losses from damaging firm capital.
- Traders must plan risk per trade relative to MDL.
- Daily loss rules interact with total drawdown and trailing drawdown limits.
- Monitoring real-time P&L is essential to avoid violations.
- Ignoring MDL is one of the most common causes of prop firm account failure.

Max Daily Loss (MDL)
Maximum amount a trader can lose during a single trading session.
Total Drawdown
Maximum cumulative loss allowed during the evaluation or funded account period.
Trailing Drawdown
Dynamic drawdown limit that increases as account equity reaches new highs.
Intraday P&L
Profit or loss generated during the current trading session.
Position Sizing
Capital allocation per trade relative to account risk limits.
What Max Daily Loss Means
Quick Answer
Max daily loss is the maximum loss allowed during one trading day.
Why it matters
It prevents traders from losing large amounts of capital during volatile market sessions.
How to do it
- Know your firm’s daily loss limit
- Monitor real-time P&L
- Stop trading before the limit is reached
Example
A $50,000 evaluation account with a 3% daily loss rule allows a maximum daily loss of $1,500.
Why Max Daily Loss Rules Exist
Quick Answer
Daily loss rules protect prop firm capital and enforce disciplined trading behavior.
Why it matters
Without daily limits, traders could potentially lose large amounts in a single volatile session.
Example
| Scenario | Outcome |
|---|---|
| Trader loses $500 | Trading continues |
| Trader loses $1,500 | Daily loss limit reached |
| Trader loses beyond limit | Evaluation failure |
How Max Daily Loss Is Calculated
Quick Answer
Max daily loss is usually calculated as a percentage of account equity or a fixed dollar amount.
Calculation formula
Max Daily Loss = Account Equity × Daily Loss Percentage
Example
| Account Size | Daily Loss % | Max Daily Loss |
|---|---|---|
| $25,000 | 3% | $750 |
| $50,000 | 3% | $1,500 |
| $100,000 | 3% | $3,000 |
Common mistakes
- Ignoring commissions and slippage
- Calculating based on incorrect equity values
Daily Loss Reset Timing
Quick Answer
Most prop firms reset the daily loss limit at the start of each new trading session.
Why it matters
Understanding reset timing helps traders plan their risk management.
Typical reset times
| Reset Method | Description |
|---|---|
| Exchange session reset | Resets when CME trading day begins |
| Midnight reset | Resets at midnight platform time |
| Rolling session | Reset based on rolling 24-hour period |
Always check the firm’s rulebook to confirm the reset schedule.
Relationship with Other Risk Rules
Quick Answer
Max daily loss works alongside total drawdown and trailing drawdown limits.
Why it matters
A trader may stay within daily limits but still violate total drawdown rules.
Example
| Rule | Purpose |
|---|---|
| Max Daily Loss | Controls intraday risk |
| Total Drawdown | Limits overall losses |
| Trailing Drawdown | Protects peak equity gains |
Strategies to Manage Daily Loss
Quick Answer
Risk management strategies help traders stay within daily limits.
Practical methods
- Risk small amounts per trade
- Use stop-loss orders
- Stop trading after multiple losses
Example
A trader with $1,500 MDL risks $300 per trade, allowing five losing trades before reaching the limit.
Example of Max Daily Loss in Practice
Scenario
| Trade | Result | Cumulative Loss |
|---|---|---|
| Trade 1 | -$300 | -$300 |
| Trade 2 | -$400 | -$700 |
| Trade 3 | -$300 | -$1,000 |
| Trade 4 | -$500 | -$1,500 |
At -$1,500, the trader reaches the max daily loss limit and must stop trading.
Common Mistakes Traders Make
- Chasing losses after approaching MDL
- Over-leveraging positions
- Ignoring commissions and slippage
- Not tracking intraday P&L carefully
- Confusing daily loss with total drawdown rules
Beginner Checklist

- Calculate your daily dollar loss limit
- Divide MDL by number of trades to determine risk per trade
- Monitor P&L continuously during trading
- Stop trading once nearing the limit
- Log all trades and daily results
