Confusion in OI and change in OI

maheshsolanke

while calling quote API, it returns OI, and if we check the OI for the same script on the NSE option chain it gets different, why it is different.
do I need to make any extra calculations on live oi?

another question is regarding the change in OI.
is there any formula to calculate Change in OI?

Thanks in advance.

This thread explains your above query.

We don't have a change in the oi field for Quote API/WebSocket stream. You can refer to this thread, to know the calculation.
