Why Orders Sent Outside Futures Trading Hours May Be Canceled
Summary
A trader asks why an order receives a successful cancellation response outside trading hours. The replies explain that an order submitted during a non-trading period may be canceled by the interface, with a response generated locally rather than by the simulated matching engine. The discussion says the same behavior can occur in live trading.
The exchange is a brief forum answer, not a detailed account of broker or exchange rules. It does not identify a specific gateway configuration, contract, or session schedule, so the behavior should be checked against the relevant interface and trading calendar. Its practical lesson is that a cancellation acknowledgment outside market hours may reflect rejection or cleanup of an off-session order rather than a cancellation processed through normal market matching.
Key ideas
- Orders submitted outside trading hours may be canceled by the interface.
- A cancellation response can be generated locally without reaching the simulated matching engine.
- The replies say this behavior may also occur in live trading.
- The discussion does not specify interface settings or contract-specific session rules.
