I was wondering if the sequence counter was incremented for the Login message. In the FIX 4.1 specs it is never mentioned explicitly. Thanks
The MsgSeqNum is unique and increments for all messages as of FIX 4.0.
The “FIX MESSAGE FORMAT AND DELIVERY” section’s “Sequence Numbers” subsection specifies “All FIX messages are identified by a unique sequence number”. The “SESSION PROTOCOL” section’s “Message Recovery” subsection specifies “Each message is assigned a unique (by connection) sequence number which is incremented after each message. Likewise, every message received has a unique sequnece number and the incoming sequence counter is incremented after each message”. There are no exceptions for the Logon or other admin messages as there were prior to version 4.0.
