Message Notes

The Gateway Status (UAT) message is used to return the status of a TT Gateway in response to a Gateway Status Request (UAR) message. The message contains a repeating group including one of the following types of data:

  • Snapshots of the current status for each server on each TT Gateway
  • Ongoing subscription status changes for each server whose status changes

If FIX Adapter loses its connection to a TT Gateway that is configured as a Price Proxy, it sets the value of Tag 58 (Text) to the following:

The connection to the price proxy server has been lost. You will be able to receive market data for prior subscriptions, but you will not be able to make new subscriptions until the connection is reestablished.
