Connection.TcpNoDelayOption	Option to improve latency at the expense of message throughput (TCP_NODELAY).	true
ConnectionRetries.Number	Number of attempts to restore the telecommunication link.	3
ConnectionRetries.Interval	The time interval between the attempts to restore the telecommunication link (in seconds).	180
Dialect	Specify the path to the XML file with the description of the FIX Dialect.	Empty

When either end of the connection has not received any data for (HeartBtInt * (100 + ReasonableTransmissionTime)/100) seconds, it will transmit a Test Request message. If there is still no Heartbeat message received after (HeartBtInt * (100 + ReasonableTransmissionTime)/100) seconds then the connection should be considered lost and corrective action be initiated.	20
