[GNC] Revisiting Quotes (Bruce Schuck)

[Kalpesh Patel]

Bruce -

The Python3 yahoo_fin module code installed on my instance looks at "https://query1.finance.yahoo.com/v8/finance/chart/" URI while Python2.7 yahoofinance module code installed on my instance looks at "https://query1.finance.yahoo.com/v7/finance/download/{i}" URI with routine to grab the crumbs. Reading things around I came across https://metacpan.org/dist/Finance-QuoteHist/source/lib/Finance/QuoteHist/Yahoo.pm which I believe has the best explanation and the corresponding Perl code to extract them dynamically. 

I have a web scraping perl module that provides EOD price only. Would there be any interest in reviewing it? That is what I put together for myself as an interim F::Q that does not rely on any yahoo API.

Colin,

While I would confirm if the Python source is grabbing the normal web page or the API calls we use(d) in F::Q, this did give me the idea to search CPAN. I found the module Yahoo::Finance which may also be a good start and possibly does the heavy lifting already.

Thanks a bunch for the info!
