When I open a data stream via DeliveryFactory.CreateStream(...) I can supply callback methods e.g. OnRefresh(MyRefershHandler). This handler will then receive the message in form of a json object (JObject message). Is there a description somewhere listing the data that can be expected here, or in the other callbacks?
For example part of the message can be:
What are valid values for "Timeliness" or "Rate" I need to test for?
The RDP Library is an ease of use wrapper around the Websocket API.
Note that the actual possible values for Timeliness, rate and rateinfo - will depend on the feed you are connecting to. If connecting to a Deployed session, then this will be controlled by internal your Market Data team. If connecting to a Platform session i.e. ERT in Cloud, I believe there is currently only one Qos available - but please double check with your Refinitiv Account team.
