NSE website new version is becoming effective now and old version will not be available after August 31, 2020.
In the new site, Market Data under Equity/Stock is now presented like this:
The 365 day Change and 30 day change columns are gone.
We were using 30 day change as a measure of weakness or strength by comparing stock price change with the change in NIFTY.
We can work that out by getting deeper into the details but not being able to see it at a glance is a disadvantage.
New Link for same data:
I tried to find the data in the form we are familiar with and found it on Economic Times site.
We can use this link for our purpose.
After that it is simple.
Further details can be checked from the Option Chain in NSE website.
Readers are welcome to share their suggestions if they find data in same form anywhere else.
