Approaches to Failover


The points of potential systems failure when using the NASDAQ_OMX_EU Gateway include the NASDAQ_OMX_EU Gateway, the exchange host, and all network devices in-between. This chapter's discussion is restricted to total software and/or hardware failure, its specific impact on NASDAQ_OMX_EU Gateways, and available options for disaster recovery.

Orders on Disconnect

When requesting login credentials, users can work with the exchange to configure the behavior of orders on disconnect. This allows orders to automatically delete on disconnect or enter a Held state for a certain period of time.

The exchange can set orders to react to a FIX session disconnect as listed below:

  • Keep all orders working at the exchange
  • Suspend all outstanding orders
  • Suspend all outstanding orders except overnight orders (i.e., GTC/GTD)
