Hi,
I am trying to backtest my nifty50 options strategy (something similar to iron butterfly) on historical nifty50 option chain dump. I had downloaded nifty50 spot historical data , nifty50 options call and put historical data for past 70 months from nse website . But the data is available as 4 values per day (open ,high ,low and close per day) . But what I am looking for is nifty50 option chain dump every 5 /10 minutes (120/60 option chain dumps per day) which will be helpful to backtest my strategy more confidently.
Is there any way I can get the data I am looking for ?
Thanks
Srinidhi
