Thank you for your reply.

Got your point. But then how some algo platforms backtesting their strategies and providing the P&L and other reports? Is their any other way to do it? Please suggest. I'm completely new in this.

Thank you.

Hi,

For backtesting a banknifty strategy I need to know the ltp of a particular strike price. And also I have required the token, symbol and expiry date for getting ltp. But I don not know how to get old expiry dates.

Please show me the way how to get it.

Thank you.

Hi,

I'm writing a banknifty strategy in python. In the running market I'm getting current expiry dates as well as future expiry dates from the below link -- https://margincalculator.angelbroking.com/OpenAPI_File/files/OpenAPIScripMaster.json

But I need the old expiry dates for backtesting which are already past.
For getting ltp I need to prepare the tradingsymbol (BANKNIFTY19JUN2450000PE) which consist of symbol, expiry date, strike price and CE/PE which will return me the token.

Using token and tradingsymbol we can get the ltp from the API.

But unfortunately I couldn't find any solution to get the old expiry dates. Please help to sot out this problem.

Thank you.
