Finance::YahooQuote - Get stock quotes from Yahoo! Finance


use Finance::YahooQuote;
# setting TIMEOUT and PROXY is optional
$Finance::YahooQuote::TIMEOUT = 60;
$Finance::YahooQuote::PROXY = "";
@quote = getonequote $symbol; # Get a quote for a single symbol
@quotes = getquote @symbols; # Get quotes for a bunch of symbols
useExtendedQueryFormat(); # switch to extended query format
useRealtimeQueryFormat(); # switch to real-time query format
@quotes = getquote @symbols; # Get quotes for a bunch of symbols
@quotes = getcustomquote(["DELL","IBM"], # using custom format
["Name","Book Value"]); # note array refs


NOTE : As of November 2017, the module is no longer all that useful as Yahoo! decided to halt the API service it relies on.

This module gets stock quotes from Yahoo! Finance. The getonequote function will return a quote for a single stock symbol, while the getquote function will return a quote for each of the stock symbols passed to it. getcustomquote allows to specify a format other than the default to take advantage of the extended range of available information.

The download operation is efficient: only one request is made even if several symbols are requested at once. The return value of getonequote is an array, with the following elements:

0 Symbol
1 Company Name
2 Last Price
3 Last Trade Date
4 Last Trade Time
5 Change
6 Percent Change
7 Volume
8 Average Daily Vol
9 Bid
10 Ask
11 Previous Close
12 Today's Open
13 Day's Range
14 52-Week Range
15 Earnings per Share
16 P/E Ratio
17 Dividend Pay Date
18 Dividend per Share
19 Dividend Yield
20 Market Capitalization
21 Stock Exchange

If the extended format has been selected, the following fields are also retrieved:

22 Short ratio
23 1yr Target Price
24 EPS Est. Current Yr
25 EPS Est. Next Year
26 EPS Est. Next Quarter
27 Price/EPS Est. Current Yr
28 Price/EPS Est. Next Yr
29 PEG Ratio
30 Book Value
31 Price/Book
32 Price/Sales
34 50-day Moving Avg
35 200-day Moving Avg

If the real-time format has been selected, the following fields are also retrieved:

36 Ask (real-time)
37 Bid (real-time)
38 Change in Percent (real-time)
39 Last trade with time (real-time)
40 Change (real-time)
41 Day range (real-time)
42 Market-cap (real-time)

The getquote function returns an array of pointers to arrays with the above structure.

The getonequote function returns just one quote, rather than an array. It returns a simple array of values for the given symbol.

The setQueryString permits to supply a new query string that will be used for subsequent data requests.

The useExtendedQueryFormat and useRealtimeQueryFormat are simpler interfaces which append symbols to the default quote string, as detailed above.

The getcustomquote returns an array of quotes corresponding to values for the symbols supplied in the first array reference, and the custom fields supplied in the second array reference. Here the custom fields correspond to the ’named’ fields of the list below.

Beyond stock quotes, Finance::YahooQuote can also obtain quotes for currencies (from the Philadephia exchange -- however Yahoo! appears to have stopped to support the currency symbols in a reliable manner), US mutual funds, options on US stocks, several precious metals and quite possibly more; see the Yahoo! Finance website for full information. Finance::YahooQuote can be used for stocks from the USA, Canada, various European exchanges, various Asian exchanges (Singapore, Taiwan, HongKong, Kuala Lumpur, ...) Australia and New Zealand. It should work for other markets supported by Yahoo.

You may optionally override the default LWP timeout of 180 seconds by setting $Finance::YahooQuote::TIMEOUT to your preferred value.

You may also provide a proxy (for the required http connection) by using the variable $Finance::YahooQuote::PROXY. Furthermore, authentication-based proxies can be used by setting the proxy user and password via the variables $Finance::YahooQuote::PROXYUSER and $Finance::YahooQuote::PROXYPASSWD.

Two example scripts are provided to help with the mapping a stock symbols as well as with Yahoo! Finance server codes. The regression tests scripts in the t/ subdirectory of the source distribution also contain simple examples.

How can one figure out the format string?
Provided a My Yahoo! ( account, go to the following URL:

Viewing the source of this page, you will come across the section that defines the menus that let you select which elements go into a particular view. The <option> values are the strings that pick up the information described in the menu item. For example, Symbol refers to the string "s" and name refers to the string "l". Using "sl" as the format string, we would get the symbol followed by the name of the security.

The example script shows this in some more detail and downloads example .csv files using GNU wget.

What about different stock symbols for the same corporation?
This can be issue. For the first few years, Yahoo! Finance’s servers appeared to be cover their respective local markets. E.g., the UK-based servers provided quotes for Europe, the Australian one for the Australia and New Zealand and so on. Hence, one needed to branch and bound code and map symbols to their region’s servers.

It now appears that this is no longer required, which is good news as it simplifies coding. However, some old symbols are no longer supported -- yet other, and supported, codes exist for the same company. For example, German stocks used to quoted in terms or their cusip-like ’ WKN ’. The main server does not support these, but does support newer, acronym-based symbols. The example script helps in finding the mapping as e.g. from 555750.F to DTEGN.F for Deutsche Telekom.
