Pre-Market Rejected Orders in an Option Hedging Engine

Summary

This short forum post reports that version 1.2.0 of an option hedging engine and its monitoring component appear to submit many orders before the market opens, with those orders rejected. The author suggests the components should check whether the current time falls within market hours and observes that the code already appears to include a check involving the current tick. The underlying issue is therefore framed as a possible mismatch between time gating and tick handling.

The excerpt offers no code, instrument details, exchange schedule, or confirmed diagnosis, and it does not show whether the proposed check was changed or resolved the behavior. It is useful as an operational reminder that automated order submission needs reliable session-time controls and that existing tick checks may not prevent pre-open submissions. The report gives no counts, trading losses, or evidence of a general defect across other installations.

Key ideas

• The report describes rejected orders submitted before the market opens by an option hedging system.
• The author suspects the system needs a market-hours check.
• The excerpt notes that a current-tick check may already exist in the code.
• It provides no confirmed cause, fix, or evidence beyond the reported behavior.
