When we read spot rates at same time from retuers using EIKON and RFA API's will it match?

  • Hi @Harihara

    As mentioned in the other query, RFA is a content agnostic API used to consume realtime data from a server.

    When you consume realtime data using RFA, in theory, you can expect to get the same data at the same tick rate and timeliness as Eikon. However, there could be some variances e.g.

    • There may some timing differences - depending on the routing of the data, so a tick may be received sooner by the RFA application than Eikon for example
    • Sometimes, the EIKON realtime data is fed with an conflated feed (not every tick is sent downstream)
    • With RFA, you may also be consuming an internally conflated service
    • Or you may be consuming a delayed feed -so the data is delayed (internally) and would arrive later than the Eikon data.

    Quite often an organisation publishes realtime data internally on multiple services with conflation and/or delays - in addition to the full tick non-delayed service.

    This is again something that you would need to confirm with your Market Data - to check if the Eikon is conflated and if the TREP service which you are consuming using RFA is conflated or not.
