Enhancement

[AtharvS321]

hello varun,
Thanks for this project. i want to do some modifications in the application please help me in that

1. I want to add login interface for the app
2. I want the calculation of all strike prices in the window instead of a particular strike price which we do by selecting the strike price at starting
   It would be very helpful if you do the above enhancements.

Yes that would be a great option to have.
