RDP Pricing Streaming API

How often do we need to re-subscribe for a symbol?

How many RICs can we subscribe to within each subscription request?

Can the same jwt be used for socket and to retrieve pricing?

What modes can we use for transport? And what are the differences between data formats of price streaming (rwf/tr_json2)

Hello @bindia.nair,

For these starter questions it is best to read through the API overview page and see the quickstart guide.

Websockets API (tr_json2 protocol)

Real time SDK (Java) (rwf/rssl protocol)

The number of RIC's etc depend on your system, what infrastructure you connect to and which SDK you use etc.

Hello @bindia.nair

About the JWT, if the client is the Pricing Streaming (Wealth - Service ERT_FD3_LF1) , the authentication does not support the JWT yet.

Hello @bindia.nair

About the first question (How often do we need to re-subscribe for a symbol?).

  • If you are requesting the "streaming" data, you do not need to re-subscribe RIC, the request stream will be keep opened and send streaming data (refresh and update messages) to the application when there is a data changed on that RIC
  • If you are requesting the "snapshot" request, the application just receives a refresh message to the application and then the request stream is closed. If you need another snapshot data of that RIC, you just re-request it as a snapshot.

I also highly recommend the client checks the 10 important things you need to know before you write a Real-Time application article.
