While fixing my stock project, I hit a road block, that Yahoo's free finance API is gone!, no more. This is quite a bummer. How to get daily quotes so to reestablish the data stream? Well, as a the beauty of free market, someone is always up to the service if there is a demand. So I ended up using Alpha Advantage API for a change.

    Tagging on top the World Snapshot project, this one is essentially a graph browser that takes the API data stream based on user selected company symbol, and draw all the data index on a single page.
