Managing Overrides in Automated Futures Trading Systems
Summary
The author examines the risks of manually changing or exiting trades generated by automated futures systems. The central recommendation is to let a system manage an open position when its rules remain valid, while reserving intervention for rare, unusual risks identified before the trading day. Suggested monitoring habits include checking at intervals, muting alerts, limiting access to controls, and building predefined failsafes and alternate exits into the system.
The author reports a one-week live experiment involving ten trades, comparing system outcomes with discretionary overrides. The reported difference favored following the system, and interventions sometimes caused unintended reverse positions after the system's trailing stop acted. The author also notes that manual changes contaminate performance records and can encourage further interference. These observations are personal and based on a very small sample; they do not establish that overrides generally reduce returns. The article offers practical process advice, not a controlled study or universal rule for handling system failures.
Key ideas
- Manual intervention can undermine the rules and performance measurement of an automated strategy.
- The author's small live sample showed worse results after overrides, but it is not statistically conclusive.
- The author favors making any exceptional risk adjustments before trading begins.
- Monitoring at set intervals and reducing prompts can help limit impulsive trade changes.
- Predefined failsafes and exits can encode appropriate interventions into system logic.
