Isn't this data the same one can get from Yahoo Finance?

    I have it working pulling historical data based on symbol
    • SirLJ 9y ago
      Sure, but there are maybe over 10000 companies including non existing ones and you need them all for your back testing to be valid...

        I see your point. Scripting this and running on cron could help.
        • SirLJ 9y ago
          Make sure the delisted companies are included...
