Parameter

Description

[PriceServer]

RetransmissionID

Sets the exchange-provided RetransmissionID used to request missing data from the exchange during recovery scenarios (e.g., intra-day Price Server restarts).

MulticastGroup=Channel1

MulticastGroup=Channel2

Sets the name for each multicast group the TFX Gateway subscribes to. TFX Gateway install with the correct values listed for the MulticastGroup parameters and do not require an additional configuration.

This value matches the channel section header in the MuticastGroups.cfg file.

NetworkInterface

Sets the IP address for a dedicated network interface card (NIC) in trading environments that utilize multiple NICs.

In addition, you may assign a separate NIC for each price feed by using the NetworkInterfaceA and NetworkInterfaceB parameters.
