I am new to this API and i came to know that there are 2 price ranges i.e 2000 and 4000 for Historical data. I am trying to fetch the intraday OI data and IV data of Nifty option strikes. To my knowledge Historical data is something which has previous day data so is it possible to get the intraday data of OI and IV with the 2000 rupees package or do i need to take the 4000 rupees pack.
You can get OI in live market data using Websocket API. IV data is not there in the Kite Connect. I think you can do calculations at your end using the live market data.
Are you looking for live OI or previous minute's OI?
