I can see that in Historical class OI is present but while retrieving the field value its returning Zero. Please let me know how can I get the data for FNO contracts in Dot Net client.
I have run in debug mode and attached a screen for Instrument = 11530754 i-e for NIFTY20FEBFUT. You can see that the returned OI is Zero. But other values are there in Historical.
Sorry .. I didn't realize that an additional OI Parm is provided ... I set it to true and now getting the data .. Thanks for your help and quick response .. Much appreciated !
