How to programatically (Python) scrape streaming live stock chart ticker data and its indicators
I have been working on a personal educational project to scrape stock and indicators' data from live chart of the stocks in Python. It could be from Yahoo Finance or investing.com or other similar websites. I know how to scrape data from basic websites but have no clue on how to scrape data from live charts [specially indicators] and store them in numpy array in a meaningful way. Below is the view and link to a sample chart.
Link to the chart view. If same view is not visible click on expand view button on top right corner of the chart block
Any help would be appreciated. A nice to have feature would be the ability to select different timeframes and then scrape data.
[EDIT 1]
As per the suggestions given in the comments i tried to use Scrapy but that is not how i want to resolve the issue. What i am trying is to get the data without loading a browser.
Grateful if someone can help.

It would be preferable to find an API that makes the data you're looking for available.

Thanks a lot for the response. However, as I mentioned the purpose it to learn the process. Also, as far as I know, these websites do not provide an API.

You should take a look at scrapy.org, this is a mature web scraping framework
