Real-time, stock data and historical pricing using the Google Finance API.
On November 1st, 2017, Yahoo Finance terminated public access to the API and stock_quote ceased to function in it's current state. Therefore, Version 1.5.0 now utilizes the Google Finance API and although functionally similar, the results, and therefore attributes, have changed. Please update accordingly.
To install the 'stock_quote' ruby gem:
gem install stock_quote
To use the gem in your Rails Application, include it in your Gemfile:
You can get a current quote with the following syntax:
stock = StockQuote::Stock.quote("symbol")
Where symbol equals the company stock symbol you want a quote for. For example, "aapl" for Apple, Inc.
You may search for multiple stocks by separating symbols with a comma. For example:
stocks = StockQuote::Stock.quote("aapl,tsla")
These queries will return a Stock object or an array of Stock objects which you may iterate through.
Each stock object has the following values:
symbol, exchange, id, t, e, name, f_reuters_url, f_recent_quarter_date, f_annlyal_date, f_ttm_date, financials, kr_recent_quarter_date, kr_annual_date, kr_ttm_date, c, l, cp, ccol, op, hi, lo, vo, avvo, hi52, lo52, mc, pe, fwpe, beta, eps, dy, ldiv, shares, instown, eo, sid, sname, iid, iname, related, summary, management, moreresources, events
History is available by providing and start date, or a start date and end date.
stock = StockQuote::Stock.history("symbol", "start_date", "end_date")
The stock instance will contain a symbol and history attribute, containing an array of hashes including date, open, high, low, close and volume.
Date format is impressively flexible. 01-Jan-2016, 01-January-2016, January 01, 2016, 01/01/2016, 01-01-2016, 01-01-16 are all accepted.
If you prefer raw json as opposed to Stock instances, you may use the following convenience methods:
stocks = StockQuote::Stock.json_quote('aapl')
stocks = StockQuote::Stock.json_history('aapl')
All other options are also available.
Special thanks to
Yahoo Google for making this api publicly available.
