Will the Websocket API support other analytics data types, for example entity data and company news?
WebSocket API currently delivers only data that is available on the Elektron real-time network (pricing, news, order book etc). TR provide separate APIs for other data sources. Please see here: APIs by Content.
This question was first asked in an Introduction to the Elektron WebSocket API webinar (29th of Nov). Please see here: Introduction to the Elektron WebSocket API
