I am trying to identify way how we can identify if a index is ticking real time or not. Is there a datapoint which provides the last tick time? Also if the index is decimating the stale value how can that be identified ? Is there a datapoint which would tell us if the index data is stale and the exchange is open ?
I am using the Refinitiv excel plugin, so trying to find a datapoint which would help to provide this data.
