Is there any notion of a trader login msg using FIX? Some exchanges, such as LIFFE and XETRA, require individual traders to login to the exchange before submitting orders. I am well aware of the msg type A for estabilshing the session connection, but is there another msg type generally used for sending trader logins?

Jeff,

The FIX spec doesn’t directly support trader logon, but does open the door for “privately defined” messages sent between two counterparties - FIX 4.3 vol 6 p 15. If trader logon is a business requirement in your implementation of FIX, define and publish the messages you need in your “rules of engagement” and if appropriate propose them to the Global Technical Committee to be included in the next edition of the spec.

Another approach might be to provide trader’s userid and p/w within the <Parties> block on each business message (i.e. Order).
