NAME
       Finance::QuoteHist::SiliconInvestor - Site-specific class for
       retrieving historical stock quotes.

SYNOPSIS
         use Finance::QuoteHist::SiliconInvestor;
         $q = Finance::QuoteHist::SiliconInvestor->new
            (
             symbols    => [qw(IBM UPS AMZN)],
             start_date => '01/01/1999',
             end_date   => 'today',
            );

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

DESCRIPTION
       Finance::QuoteHist::SiliconInvestor is a subclass of
       Finance::QuoteHist::Generic, specifically tailored to read historical
       quotes from the Silicon Investor web site
       (http://www.siliconinvestor.com/). Silicon Investor does not currently
       supply information on dividend distributions or splits.

       For quote queries in particular, at the time of this writing, the
       Silicon Investor web site utilizes start and end dates, returns data
       200 entries at a time. The "quote_urls()" method provides all the URLs
       necessary given the date range and symbols. These are automatically
       utilized by the native methods of Finance::QuoteHist::Generic.

       Please see Finance::QuoteHist::Generic(3) for more details on usage and
       available methods. If you just want to get historical quotes and are
       not interested in the details of how it is done, check out
       Finance::QuoteHist(3).

METHODS
       The basic user interface consists of a single method, as shown in the
       example above. That method is:

       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. Quote values are
           pre-adjusted for this site.

REQUIRES
       Finance::QuoteHist::Generic

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.

       In the case of The Silicon Investor, as of November 27, 2000, their
       statement reads, in part:

        All information provided by S&P ComStock, Inc. ("ComStock") and its
        affiliates (the "ComStock Information") on Silicon Investor World
        Wide Web site is owned by or licensed to ComStock and its affiliates
        and any user is permitted to store, manipulate, analyze, reformat,
        print and display the ComStock Information only for such user's
        personal use. In no event shall any user publish, retransmit,
        redistribute or otherwise reproduce any ComStock Information in any
        format to anyone, and no user shall use any ComStock Information in
        or in connection with any business or commercial enterprise,
        including, without limitation, any securities, investment,
        accounting, banking, legal or media business or enterprise.

       There you have it. If you feel like you might have concerns with this
       then first double check the statement on the bottom of this page:

         http://www.siliconinvestor.com/misc/terms.html

       If you still have concerns, then use another site-specific historical
       quote instance, or none at all.

       Above all, play nice.
