AUTHOR:

DATE:
Thursday, 28th Nov., 2024
OBJECTIVE:
To provide a way to retrieve dates of important events like financial-results, stock-splits, fund-raising, etc.
from NSE's portal.
NOTE: This method involves web scraping. It is good for proof-of-concept development, but it is recommended that
more professional data-sources be used when the product starts becoming mature.

AUTHOR:

DATE:
Thursday, 5th Dec., 2024
OBJECTIVE:
To provide a way to retrieve the list of holidays from NSE and to check if today is a holiday.
NOTE: This method involves web scraping. It is good for proof-of-concept development, but it is recommended that
more professional data-sources be used when the product starts becoming mature.
