This is a program written in python. I have used selenium and chrome driver for data scraping. The program only needs internet for scrapping data or viewing news, after data is scraped you can fully use it in offline mode. If the website gets updated from which the data is being scrapped, the program will not be able work :(
Fundamental Analysis as well as Technical Analysis of companies listed in Nepal Stock Exchange can be done using this program. The files here have data till 2022-2-22.
