in TREP APIs

Hello, we are using RFA 8.1 C++ API to consume Level 1 and Level 2 market data. Could you please share the code changes and configuration adjustments needed on the Publisher[Testserver/TREP demo tool] side to close active subscriptions by consumers?

    Hi @mktdata,

    Can you please clarify your question. Are you asking if the testserver - a tool provided with RTMDS infrastructure can actively close a subscription (without the unsubscribe request from consumer)?

    testserver it is a pre-compiled binary and doesn't allow this functionality. You might be able to use similar publisher examples from the RTSDK - EMA or ETA and simulate the publisher functionality after code changes.

    Hi @Gurpreet we have sample RFA 8.1 C++ API which contains sample publisher example code. Could you please provide api names / code change required in publisher side to reproduce following scenarios,

    1) To close active consumer subscription.

    2) Name change of actively subscribed RIC.

    Hi @mktdata​,

    Which example is it based on? Is it an interactive or NI provider?

    The QuickStartProvider example packaged in the RFA SDK package can answer some of your questions.

    @mktdata,

    I am not aware of any means to send the name change of an instrument. To do so, you will have to close the previous active subscription - and your consumer will have to somehow discover the new RIC.

    To close an active subscription from the provider - you application will have to send a CLOSED status message. You might choose to include the new RIC name in the status text. There are examples of status message in the provider examples.
