Refinitiv Real-Time Managed Distribution Service instrument limit

Hello!

I have several questions about "instrument limit":

1) How does this limit counted? I mean, if I have the limit of 1000 instruments, does it mean that I can subscribe to the Market Price domain for 1000 symbols?
If I need both MBP and MP domains, I can subscribe only for 500 instruments?

2) What is an expected behavior when I am trying to register a new OmmConsumer which exceeds this limit?

    Hi @Nikita

    Can I assume you are referring to the ADS config parameter:

    itemLimit : Sets the maximum number of allowable open items per user per service.

    OR

    aggregateItemLimit:Sets the maximum number of allowable open items per user for all services

    I would expect the limit to be in relation to the total number of open streams/items at any given point in time. As an MBP stream and MP stream for the RIC would represent two streams I would expect it to count as 2 towards your limits - so you would be limited to 500 MPB and 500 MP for example.

    In terms of exceeding the limit, I would expect you to receive a Status Message with a Closed Stream state and a Status code such as TOO_MANY_ITEMS.

    More likely you would see something like the following:

    'A20: Aggregate item limit exceeded.'" - Forum | Refinitiv Developer Community
