Dynamically subscribe symobls in EMA API

hello,

we're moving to EMA from RFA API. We'd like to be able to subscribe a symbol when the application is running. i.e., after an initial subscription of all symbol items and application is already running streaming data, we want the ability to add a (either missed or new) symbol into the subscription. Just want to make sure we can use the same registerClient() call to register new symbol? If not, wondering how it can be done via EMA C++ API. thanks,

Hi @jzhao, the runtime subscription to new instruments is no different than the startup subscription request.

You can invoke the registerClient() with new instrument at any time.
