ListenPort | FIX Engine listens on this port for incoming connections:
Comma delimited list could be used to specify more than one listen port. | 0 |
LocalInterfaces | Specifies local interfaces where engine listen for incoming connections. Each local interface specification could specify the local IP address and port. For instance "localhost" and "192.168.0.1:4501" are valid values. When a local interface specification contains the same port as specified at listenPort settings the listening appears only on the interface and port specified at localInterface setting. | Empty |
Log.CreateEngineLogFile | Option to create the FIX Engine log file. | true |

ProcessDeliverToCompID | Option to process the DeliverToCompID (tag 128) flag. | false |
ReasonableTransmissionTime | The reasonable transmission time as % from HeartBtInt value. 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 a corrective action is initiated. | 20 |
Reconnect.Attempts | Number of attempts to restore the FIX connection. | 3 |
Reconnect.Interval | The time interval between the attempts to restore the FIX connection (in seconds). | 180 |
Resending.QueueSize | Number of sent messages that are available for resending on counterparty's Resend Request <2> message. | 1000 |
Resending.ResendRequestMaximumRange | The maximum number of messages to be requested in one Resend Request (MsgType=2) message. | 0 (Unlimited) |
ReportNewMessagesWhileWaitingForMissedMessages | When the message gap is detected the Resend Request <2> FIX Message is sent and Session state is changed to "AwaitReplyOnResendRequest". By default in this state, the incoming new messages (without the PossDupFlag (tag #43) flag) are ignored because we expect them to be re-sent later again with the PossDupFlag flag. This property allows to change this behavior and report the new messages anyway. In this mode messages could be reported out of the original order: e.g. MsgSeqNum could be: 3 (original), 4 (original), 2 (PossDupFlag='Y'), 3 (PossDupFlag='Y'), 4 (PossDupFlag='Y') and some messages could be received two times: first time without PossDupFlag='Y' and second time - with this flag. | false |
