This is a simple Yahoo Finance module capable of getting current data for several symbols in bulk as well as individually. Additional features include getting stock symbols filtered by stock market.

1. Add yahoo_finanza to your list of dependencies in mix.exs:

   def deps do [{:yahoo_finanza, "~> 0.2.3"}] end

2. Ensure yahoo_finanza is started before your application:

   def application do [applications: [:yahoo_finanza]] end

Getting symbol list for a market

YahooFinanza.Symbol.symbols "market" ## => {:ok, ["symbol1", "symbol2", ..., "symboln"]}

Note: The available markets are: "amex", "nyse", "sp_500", "dow_jones", "nasdaq" To add a new market or listing simply add the csv file to the markets directory and add the market or listing name to the markets.csv file.

Getting stock quote for a single symbol

{:ok, quotes} = YahooFinanza.Quote.fetch(["AAPL"]) ## => {:ok, [%{"Symbol" => "AAPL", ... }]}

It's properties can be accessed like so:

quote = quotes |> List.first
quote["Ask"] ## => 12.0

Getting stock quote for multiple symbols

{:ok, quotes} = YahooFinanza.Quote.fetch(["AAPL", "FB"]) ## => {:ok, [%{"Symbol" => "AAPL", ... }, %{"Symbol" => "FB", ... }]}

Each quote can be accessed like so:

apple = quotes |> List.first ## => %{"Symbol" => "AAPL", ... }

Combining the Symbol and Quote Modules

{:ok, nyse_symbols} = YahooFinanza.Symbol.symbols "nyse"
{:ok, nyse_quotes} = nyse_symbols |> Enum.take(100) |> YahooFinanza.Quote.fetch
