Daily and Weekly Loss Limits: Circuit Breakers
Bad days cascade. A hard stop prevents one bad trade from becoming a blown account.
Researched and written by Laurent Why Loss Limits Exist
After two or three losses in a row, something happens psychologically: you want to "make it back." You start taking trades that don't fully meet your criteria. You increase position size. You move your stop-loss further away to "give it room." Each of these decisions makes the next loss bigger, which makes the urge to recover stronger. This is the revenge trading spiral, and it has destroyed more accounts than any market event.
Daily and weekly loss limits are circuit breakers. They forcibly stop you before the spiral takes hold.
Recommended Limits
| Limit | Amount | Action When Hit |
|---|---|---|
| Max daily loss | 3% of account | Stop trading for the day. No exceptions. |
| Max weekly loss | 5% of account | Stop trading for the week. Review journal. Analyze what went wrong. |
| Max monthly loss | 10% of account (optional) | Reduce position sizes by 50% for the rest of the month. Deep strategy review. |
Implementation
Write your limits on a physical card and tape it to your monitor. Before every trade, check: "How much am I down today? This week?" If you're at 2.5% daily loss and your next trade risks 1%, you know that a loss would put you at 3.5%, which exceeds your daily limit. Either take the trade with reduced size (0.5% risk) or wait until tomorrow.
Key Takeaways

- • Professional prop firms enforce these limits. You should too.
- • The purpose: prevent one bad day from becoming a catastrophe through revenge trading.
