@Mahesh Wankhede

Thanks for the suggestion, Mahesh. We are in the process of doing daily updates to the simulator data. Once this is done, we will allow simulating with expired, existing, and future expiry contracts as well.

Thanks for your valuable Suggestions, Mahesh

Regarding point number one & two - it is already in work. You will see OI in the option chain of the strategy builder and simulator in one of the next few updates

Good suggestion regarding some improvements. We will work on these suggestions and you will see some changes there are well. Thanks again.
