# setting TIMEOUT and PROXY is optional
$Finance::YahooQuote::TIMEOUT = 60;
$Finance::YahooQuote::PROXY = "http://some.where.net:8080";
@quote = getonequote $symbol; # Get a quote for a single symbol

DESCRIPTION
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

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.

FAQs
How can one figure out the format string?
Provided a My Yahoo! (http://my.yahoo.com) account, go to the following URL:
http://edit.my.yahoo.com/config/edit_pfview?.vk=v1
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 examine_server.sh 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 examine_server.sh helps in finding the mapping
as e.g. from 555750.F to DTEGN.F for Deutsche Telekom.
