Actually, You can make a wrapper of NSEAPI. Here is the link - aeron7/nsepython I made this for my own use when I created the Stock Options Dashboard
Link - Stock Options Open Interest
You need to remember the core of the theory that, Maxpain Changes !! It is not the alchemy you’re looking for. But it is definitely an underrated tool that works far better than overrated tools like moving average.
- It updates every 30 mins.
- It updates the IV, 1SD Range, PCR, Highest, and 2nd Highest OI of both Call and Put side.
- Lower and Upper Range as per the implementation of OI We follow as seen here at How to trade options using Max Pain Theory?.
Actually there are lots of more tools using Option Chain. Like Open Interest Dashboard
Zerodha API also gives OI data but I am more habituated with NSE APIs and their output format.
