I am using C++. The last arg, the TagValue list exist too, as I can see it in the C# doc
but I never filled it with anything.? Seems more a provision for future use.
The? keepUpToDate flags does still exist as it seems in C# too, and work as expected
I always set endDateTime as "" to get latest date. Could it be a factor that influence your behavior ?
you need to show more of the way you fill reqHistoricalData request to get an opinion.
