This page sets out the key aspects of establishing and managing sessions between a Whisperer Enterprise Client and a Feed Handler.

Logon

A FIX session is only fully established when the following stages are complete:

• Establishing a connection (typically, but not always, involving the creation of a TCP socket connection).
• Authentication: Implemented via the exchange of FIX Logon messages.
• Synchronization: Identification of lost/untransmitted messages and retransmission as necessary by either or both sides,
• Verification: Exchange of TestRequest and Heartbeat messages to explicitly confirm correct session establishment.
