if I want to do backtesting to look if any of my strategy goes wrong, then where I can do?
for E.g. - If I bought Nifty 22500 CE of 11th April Expiry on 8th April & Sold it on 10th April with a profit of 5000 Rs.
Now the CE of 11th Apr is expired. Now If I want to re-test at what levels I have done this trade, I don’t see the 11th April CE on chart as it is expired. So, in such case How can I validate it with a chart after that Expiry date is over?
