Hi,
We are using Refinitiv Realtime Optimized (Websocket API) to recieve Realtime price. We notice that sometimes the response from Refinitiv does not come back with all the data requested. We receive only partial data.
The Api is used to fetch Realtime price every 2 minutes.
To verify what the problem is, please share the code that you are using. Therefore, we can use it to replicate this issue.
You may also need to share all messages sent and retrieved by the application.

Updates are designed to present values that have changed in the backend. Many of the fields you can request will very rarely change so it is not the intention of the real-time systems to present hundreds of fields within an update when only a few change. Instead, when you request for real-time streaming data, you will receive the "Refresh" which is effectively a snapshot of the latest values. When there is any activity in the market where changes occur to an instrument, for example a trade, you will only receive the trade fields. It is up to the application to hold onto all fields within their own cache.
Alternatively, you can use the Pricing interface within the Refinitiv Data Libraries. These libraries provide a wrapper around the WebSocket service but include a layer of convenience such as requesting for streaming data and automatically managing a cache. What this means is when you open a Pricing stream for an instrument, the Pricing stream will manage updates and keep an up-to-date active cache. So, you can be notified when an update occurs and simply grab whatever fields you need within the cache.
Hi @lalith.kumar ,
Regarding the Refinitiv Websocket API - Overview, could you please confirm whether the response you got is the update message type? as the update messages only contain fields that has an update compared to the previous response
The description of Request message and Update message is described in WebSocket API Specifications and Developers Guide below
Hope this helps and please let me know in case you have any further questions.
Hi @raksina.samasiri ,
I see response type as both Refresh and Update, but most of these occurrences where we are not getting complete data are Updates.
so, is this an expected behavior? Is there a way that we can receive all the data even if there is no update.
Thanks and Regards
Lalith Kumar
