How can I retrieve instrument details and historical data for expired futures and options? I need this information for backtesting. Could you please share the relevant API or method to access these expired instruments and their historical data?
You can only get current trading instruments tokens and their historical data. You can get intraday historical data for the active options contract. Historical data won't be available for the expired option contract. However, you can get the day-period data for futures using the continuous. Go through the documentation here.
But the Groww API provides an option to fetch historical data for expiries (reference: https://groww.in/trade-api/docs/python-sdk/backtesting). So I’d like to know if there is any possibility that Zerodha will offer this feature in the future.
