@jaskirat1208 Appreciate you taking time to respond.
Though, my issue is not what you suggested.
I am looking to fetch "historical" Nifty & BankNifty futures contract prices for e.g. from 1 Jan 2018 onwards.
Usually these are only in monthly contracts (current month, near & next month), but if we refer to TradingView there we have a continuous current month contract which gives intraday candle data since almost 2 years or so.
I want that feed if possible from AngelOne coz they are my broker. I won't rely so much on TradingView historical data.
