I wanted to add couple of my findings.
for 10.19.2a both the methods:?execDetails?and?execDetailsEnd fire sucessfully.
For 10.23.2a neither of the methods fire
However if I change the settings for "Instrument Specific Attributes for dual mode API Client in" to UTC or operator time zone the two methods again fire. So this gives me a clue that something is failing due to timezones. I do trade futures contracts across multiple timezones like SGX and Eurex. So perhaps this is why I see a failure and others dont see it.
