NAME

       Finance::QuoteHist - Perl module for fetching historical stock quotes.

SYNOPSIS

	 use Finance::QuoteHist;
	 $q = Finance::QuoteHist->new
	    (
	     symbols	=> [qw(IBM UPS AMZN)],
	     start_date => '01/01/2009', # or '1 year ago', see Date::Manip
	     end_date	=> 'today',
	    );

	 # Quotes
	 foreach $row ($q->quotes()) {
	   ($symbol, $date, $open, $high, $low, $close, $volume) = @$row;
	   ...
	 }

	 # Splits
	 foreach $row ($q->splits()) {
	    ($symbol, $date, $post, $pre) = @$row;
	 }

	 # Dividends
	 foreach $row ($q->dividends()) {
	    ($symbol, $date, $dividend) = @$row;
	 }

	 # Culprit
	 $fetch_class = $q->quote_source('IBM');

DESCRIPTION

       Finance::QuoteHist is a top level interface for fetching historical stock quotes from the web.

       It is actually a front end to modules based on Finance::QuoteHist::Generic, the main difference being that it has a default lineup of web
       sites from which to attempt quote retrieval. If the prospect of mixing data from multiple sites seems scary to you, then use one of the
       site-specific modules directly.

       Unless otherwise defined via the lineup attribute, this module will select a lineup for you, the default being:

	   Finance::QutoeHist::Yahoo
	   Finance::QutoeHist::Google
	   Finance::QuoteHist::QuoteMedia
	   Finance::QutoeHist::MSN

       Once instantiated, this module behaves identically to the first module in the lineup, sharing all of that module's methods.

       Most queries will likely be handled by the first module in the lineup.  If the site is down for some reason, or perhaps that site does not
       provide quotes for defunct ticker symbols, then the other sites in the lineup will be attempted.

       See Finance::QuoteHist::Generic(3) for gory details on all of the parameters and methods this module accepts. The basic interface is noted
       below.

METHODS

       The basic user interface consists of several methods, as seen in the example above. Those methods are:

       quotes()
	   Returns a list of rows (or a reference to an array containing those rows, if in scalar context). Each row contains the Symbol, Date,
	   Open, High, Low, Close, and Volume for that date.  Optionally, if non-adjusted values were requested, their will be an extra element at
	   the end of the row for the Adjusted closing price.

       dividends()
	   Returns a list of rows (or a reference to an array containing those rows, if in scalar context). Each row contains the Date and amount
	   of the Dividend, in that order.

       splits()
	   Returns a list of rows (or a reference to an array containing those rows, if in scalar context). Each row contains the Date, Post split
	   shares, and Pre split shares, in that order.

       source($ticker, $target)
	   Each of these methods displays which site-specific class actually retrieved the information, if any, for a particular ticker symbol and
	   target such as 'quote' (default), 'dividend', or 'split'.

DISCLAIMER

       The data returned from these modules is in no way guaranteed, nor are the developers responsible in any way for how this data (or lack
       thereof) is used. The interface is based on URLs and page layouts that might change at any time. Even though these modules are designed to
       be adaptive under these circumstances, they will at some point probably be unable to retrieve data unless fixed or provided with new
       parameters.  Furthermore, the data from these web sites is usually not even guaranteed by the web sites themselves, and oftentimes is
       acquired elsewhere. See the documentation for each site-specific module for more information regarding the disclaimer for that site.
