22 NOTE: As of November 2017, the module is no longer all that useful as
23 Yahoo! decided to halt the API service it relies on.
24 This module gets stock quotes from Yahoo! Finance. The getonequote
26 function will return a quote for a single stock symbol, while the
27 getquote function will return a quote for each of the stock symbols
28 passed to it. getcustomquote allows to specify a format other than the
29 default to take advantage of the extended range of available
30 information.
31 The download operation is efficient: only one request is made even if
33 several symbols are requested at once. The return value of getonequote
34 is an array, with the following elements:
35 0 Symbol
37 1 Company Name
38 2 Last Price
39 3 Last Trade Date
40 4 Last Trade Time
41 5 Change

87 The getquote function returns an array of pointers to arrays with the
89 above structure.
90 The getonequote function returns just one quote, rather than an array.
92 It returns a simple array of values for the given symbol.
93 The setQueryString permits to supply a new query string that will be
95 used for subsequent data requests.
96 The useExtendedQueryFormat and useRealtimeQueryFormat are simpler
98 interfaces which append symbols to the default quote string, as
99 detailed above.
100 The getcustomquote returns an array of quotes corresponding to values
102 for the symbols supplied in the first array reference, and the custom
103 fields supplied in the second array reference. Here the custom fields
104 correspond to the 'named' fields of the list below.
105 Beyond stock quotes, Finance::YahooQuote can also obtain quotes for
107 currencies (from the Philadephia exchange -- however Yahoo! appears to
108 have stopped to support the currency symbols in a reliable manner), US
109 mutual funds, options on US stocks, several precious metals and quite
110 possibly more; see the Yahoo! Finance website for full information.
111 Finance::YahooQuote can be used for stocks from the USA, Canada,
112 various European exchanges, various Asian exchanges (Singapore, Taiwan,
113 HongKong, Kuala Lumpur, ...) Australia and New Zealand. It should work
114 for other markets supported by Yahoo.
115 You may optionally override the default LWP timeout of 180 seconds by
117 setting $Finance::YahooQuote::TIMEOUT to your preferred value.
118 You may also provide a proxy (for the required http connection) by
120 using the variable $Finance::YahooQuote::PROXY. Furthermore,
121 authentication-based proxies can be used by setting the proxy user and
122 password via the variables $Finance::YahooQuote::PROXYUSER and
123 $Finance::YahooQuote::PROXYPASSWD.
124 Two example scripts are provided to help with the mapping a stock
126 symbols as well as with Yahoo! Finance server codes. The regression
127 tests scripts in the t/ subdirectory of the source distribution also
128 contain simple examples.

216 How can one figure out the format string?
217 Provided a My Yahoo! (http://my.yahoo.com) account, go to the following
218 URL:
219 http://edit.my.yahoo.com/config/edit_pfview?.vk=v1
221 Viewing the source of this page, you will come across the section that
223 defines the menus that let you select which elements go into a
224 particular view. The <option> values are the strings that pick up the
225 information described in the menu item. For example, Symbol refers to
226 the string "s" and name refers to the string "l". Using "sl" as the
227 format string, we would get the symbol followed by the name of the
228 security.
229 The example script examine_server.sh shows this in some more detail and
231 downloads example .csv files using GNU wget.
232 What about different stock symbols for the same corporation?
234 This can be issue. For the first few years, Yahoo! Finance's servers
235 appeared to be cover their respective local markets. E.g., the UK-based
236 servers provided quotes for Europe, the Australian one for the
237 Australia and New Zealand and so on. Hence, one needed to branch and
238 bound code and map symbols to their region's servers.
239 It now appears that this is no longer required, which is good news as
241 it simplifies coding. However, some old symbols are no longer supported
242 -- yet other, and supported, codes exist for the same company. For
243 example, German stocks used to quoted in terms or their cusip-like
244 'WKN'. The main server does not support these, but does support newer,
245 acronym-based symbols. The example script examine_server.sh helps in
246 finding the mapping as e.g. from 555750.F to DTEGN.F for Deutsche
247 Telekom.
