The Cancel on Disconnect is a function that automatically cancels all existing valid orders (*2) entered as New Orders from a Virtual Server (Order/Notice), triggered by the loss of the TCP connection (*1) on which the Virtual Server established an operation link with the Exchange Trading System.

For orders cancelled by this function, Invalidation Result Notice Messages are sent to the Virtual Server when it reconnects to the Exchange Trading System. After orders are cancelled due to Cancel on Disconnect, operations at the Virtual Server cannot be restarted for a certain period of time (10 seconds).
To use the function, apply for use when applying for registration of Virtual Server.

(*1) It includes the loss of the TCP connection by network failure between Virtual Server and the Exchange Trading System.
(*2) If some orders subject to cancellation cannot be cancelled due to falling under non-order acceptance hours or trading halt, they are cancelled when order acceptance restarts. Orders for test issues are also subject to cancellation.
