Session Initiation

Upon an established TCP connection, the T4 FIX API basic requirement is to have the initiator and acceptor start sequence numbers from 1.

Drop of a physical (TCP socket) connection will result in the end of a FIX session. Upon reconnection, a new FIX session will be started with a sequence number of 1 (for the API User). Likewise, the T4 API server will respond with messages starting with a sequence number of 1.

Authentication Requirements

98	EncryptMethod	Y	(Always unencrypted)
108	HeartBtInt	Y	Note same value used by both sides
95	RawDataLength	N	Required for some authentication methods
96	RawData	N	Required for some authentication methods
141	ResetSeqNumFlag	N	Indicates both sides of a FIX session should reset sequence numbers
789	NextExpectedMsgSeqNum	N	Optional, alternative via counterparty bi-lateral agreement message gap detection and recovery approach
383	MaxMessageSize	N	Can be used to specify the maximum number of bytes supported for messages received
