Team,
I downloaded the instruments file from the Upstox and tried to extract out NIFTY options but can’t find historical instruments of options.
securities.JSON is the one having all instruments downloaded from Instruments | Upstox Developer API
The other 2 files I programmatically extracted NIFTY and BANKNIFTY option securities by filtering out using segment=“NSE_FO” and asset_symbol and ordered in ascending order of expiry date but you see they are of futures only.
Please help find any other way to fetch FNO historical data. (NIFTY specifically)
