About The Samples

This sample demonstrates using the Barclay's Barx Trading Components handlers to connect to and perform operations at that venue.

Setup

The BarclaysBARXMarketData.cfg and BarclaysBARXExecution.cfg files must be edited to include the correct credentials and logging information required to connect to the venue.

Please contact your venue support for them to give you these credentials and network connection information. Some information you will likely need:

  1. SenderCompID

  2. TargetCompID

  3. SocketConnectHost

  4. SocketConnectPort

The BarclaysBARXInitialSubscriptions.txt file is used to determine the initial market data requests to be sent to the venue. Review this file to see what requests will be made when running the samples.
