Real-time, stock data and historical pricing. Data provided for free by IEX.
On March 17, 2018, Google Finance terminated public access to it's API. As a result, Version 2.0.0 of stock_quote now uses the IEX Trading API (iextrading.com). Although functionally similar, the results, and therefore attributes, had 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:
gem "stock_quote", github: 'tyrauber/stock_quote', branch: 'iex'
Quote is the primary method, returning a StockQuote::Stock instance, including the following attributes (new in v2.0.0).
symbol, company_name, primary_exchange, sector, calculation_price, open, open_time, close, close_time, high, low, latest_price, latest_source, latest_time, latest_update, latest_volume, iex_realtime_price, iex_realtime_size, iex_last_updated, delayed_price, delayed_price_time, previous_close, change, change_percent, iex_market_percent, iex_volume, avg_total_volume, iex_bid_price, iex_bid_size, iex_ask_price, iex_ask_size, market_cap, pe_ratio, week52_high, week52_low, ytd_change, chart
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 (or array). 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.
Note: You can receive a raw json hash response with the following syntax:
stocks = StockQuote::Stock.raw_quote("aapl,tsla")
The raw_ method is available on all supported methods.
The IEX API is quite extensive and well documented.
V2.0.0 of stock_quote mirrors the IEX API:
- book
- chart
- company
- delayed_quote
- dividends
- earnings
- effective_spread
- financials
- stats
- logo
- news
- ohlc
- peers
- previous
- price
- quote
- relevant
- splits
- volume_by_venue
Batch allows you to batch requests. All methods in stock_quote use batch under-the-hood.
Batch follows the syntax:
StockQuote::Stock.batch(type, symbol, range)
Where type can be multiple of the above methods and symbol can be an array of company symbols.
Range can be:
5y, 2y, 1y, ytd, 6m, 3m, 1m, 1d, date, dynmaic
And are applied to chart method.
The following IEX methods are currently unsupported:
- list
- mostactive
- gainers
- losers
- iexvolume
- iexvolume
- threshold_securities
- short_interest
