Hi Varun

First of all, Great Job done and big thanks for sharing.

Will it be possible for you to change the URL "https://www.nseindia.com/api/option-chain-indices" to "https://www.nseindia.com/api/quote-derivative?symbol" and provide option of "TATASTEEL". It would be great to include all stock options. I can help in creating a list in a particular format, if you need.

I tried doing that but got following error. I am not a hardcore developer to get into it.

Fatal error: PyInstaller does not include a pre-compiled bootloader for your
platform. For more details and instructions how to build the bootloader see
