HSVF Market Data Configuration 7.18

MulticastGroup.cfg

The MX Gateway uses the MulticastGroup.cfg file to determine all market data connection settings. MulticastGroup.cfg is an index file that maps connectivity information to the various multicast groups that MX broadcasts over the HSVF market data protocol price feed, and is not configurable. Connectivity information to the retransmission service is also included.

The MulticastGroup.cfg file stores connection information for multicast group data in unique channel sections. By default, the MX Gateway does not automatically download all of the various feeds listed in the MulticastGroups.cfg file. To download the feed for a particular multicast group, you must configure a MulticastGroup= parameter in the [PriceServer] section in hostinfo.cfg.

The file contains the following parameters:
