Is there any custom Refinitiv API that can provide us market (Exchange) open/close flag on a dynamic basis? We need to identify markets which are open at any given time. We tried to fetch market open and close time based on the following Refinitiv FIDs but we observed they are not being populated at the moment. (14528, 3877, 1392, 6692, 6693) Are they not used at the moment? We can also use INST_PHASE to identify whether the market is open or close, but this involves building a complex logic, so we are avoiding it. Kindly advise.
