The Halt Trading toggle on the Risk Settings page is a global kill switch. When on, no strategy owned by the user fires new entries. Open positions are not closed.
When to use it
- About to travel and want to avoid new exposure.
- Suspicious market event (flash crash, exchange outage) and you want to pause until you can review.
- Debugging - clean room to re-enable strategies one by one.
Difference vs circuit breakers
Circuit breakers trip automatically based on loss / drawdown thresholds. Halt Trading is manual and stays on until you toggle it off.
What halt doesn't do
- Doesn't auto-close positions. Manual or natural exit is on you.
- Doesn't disable individual strategies. When you toggle halt off, every previously-enabled strategy resumes.
- Doesn't cancel pending orders placed by the engine.
Tips
- Close positions manually at the exchange to flatten while halted.
- A daily loss breaker trip sets trading halt flag automatically. Toggling off Halt Trading without addressing the underlying loss often results in the breaker tripping again.
