The 30% Negative P&L Rule, also known as Maximum Adverse Excursion (MAE), is a risk management rule used by Apex Trader Funding to limit how much loss a trader can have on any single trade. This rule helps protect your funded account and keeps your trading strategy disciplined.
What Is the MAE Rule?
Under this rule, the unrealized loss (negative P&L) on any open trade must not go beyond 30% of your profit balance at the start of the day. This is not a daily account loss limit – it only applies to each trade separately.

Why This Rule Matters
MAE tells you the furthest point a trade goes against you before recovering. By limiting this to 30%, it encourages traders to manage risk responsibly and avoid holding big losing positions. It’s a core part of Apex’s risk rules to keep your funded account stable.
Easy Example
Let’s say you have a $50,000 trading account and your profit balance at the start of the day is $4,000.
- 30% of $4,000 = $1,200
- Your open trade loss should never go below –$1,200
If a trade starts losing more than $1,200, you should close or adjust it to stay compliant.
👉 For new or low-profit accounts, this 30% limit may be calculated using a smaller threshold instead of actual profits.
What Happens When Profits Grow?
If your account earns significant profit, Apex may let you use a 50% drawdown limit instead of 30% starting the next trading day. This gives more flexibility once you build a healthy profit. 5
Key Takeaways
- This rule is per trade, not a total daily loss limit.
- Unrealized losses must stay within 30% of your starting profit balance.
- Breaking the rule repeatedly can lead to warnings or account restrictions.

Conclusion
The 30% Negative P&L Rule (MAE) at Apex Trader Funding helps traders limit drawdowns on individual trades. By sticking to this rule and managing your losing positions, you can protect your account and trade more consistently. Always monitor your open positions and adjust when drawdowns get close to the limit.
