What is JIT conflation (RTO) and Time conflation (RTMDS WebSocket)
Our client is currently having an app based on Python that consumes RT data. They are currently using RTO which is maximum of 3 updates per second for quotes. Going forward they will use the same application to connect to RTMDS via WebSocket (300ms Conflated Service). Both RTO and RTMDS WebSocket are conflated service.…

Getting Mutual fund time series data
Hello, for my thesis I have to obtain times series return data for several mutual funds (at least monthly, but daily would be better) from 2000-today. However, the data is not available in Eikon (for example when I try it with the build formula tool in excel). Is it even possible to get return data for mutual funds in…

[EMA/C++] FieldList/UpdateMsg performance with multithreading
Hi We're in the process of developing a C++ application that will utilize RTSDK to send a rather large amounts of messages (200k+) in periodic bursts. We're basing this on Cpp EMA, and we're running multiple threads each with its own InteractiveProvider to spread business logic and encoding load between different CPU…

Api performance seems to have decreased
Hi, We have been using permID for a while now and just this last weekend have found that the response time has massively increased. Testing today with calling the match api (https://api-eit.refinitiv.com/permid/match) with the following body: name google it took 55 seconds before we got a response, we used to be able to…

EMA performance not comparable to IDS rest interface.
We are moving to the cloud and it has been suggested to use Java EMA to connect to our ADS service. It works fine for a few rics but when sending 1000+ rics the performance is much slower than when we were doing the same thing against the IDS restful interface. We basically just want to replicate the functionality of the…

Eikon python API not responding?
I have a function that runs and pulls in Benchmark Yields (I.e. US1YT=RR, EU10YT=RR, etc) for a list of 100 currencies. Currently, the function is freezing randomly in the data pull request stage from ek.get_data() where no error message or data is returned. The code is just running with no response. This occurs randomly…
