FIX Recovery - Logon

Logon (35=A) Message (Alternative Method)

Instead of sending the Recovery Request (U2) message, you can also perform a Recovery Request using the Logon (35=A) message. You will similarly receive all valid messages within the specified timeframe.

This method allows you to forgo sending the Recovery Request (35=U2) message; however, it is subject to your application’s ability to incorporate the 916 and 917 (or 18002 for reconciliation) tags on the Logon (35=A) message.

To perform a FIX Recovery using a Logon (35=A) message including StartDate and EndDate tags method:

1. Log on
2. Receive recovered messages
3. Get automatically logged out

Note Optionally, Reconciliation can also be used.
