Finance::QuoteHist::Generic Description

Finance::QuoteHist::Generic is a base class for retrieving historical stock quotes. Finance::QuoteHist::Generic is a base class for retrieving historical stock quotes.SYNOPSIS package Finance::QuoteHist::MyFavoriteSite; use strict; use vars qw(@ISA); use Finance::QuoteHist::Generic; @ISA = qw(Finance::QuoteHist::Generic); sub url_maker { # This method returns a code reference for a routine that, upon # repeated invocation, will provide however many URLs are necessary # to fully obtain the historical data for a given target mode and # parsing mode. }This is the base class for retrieving historical stock quotes. It is built around LWP::UserAgent. Page results are currently parsed as either CSV or HTML tables.In order to actually retrieve historical stock quotes, this class should be subclassed and tailored to a particular web site.In particular, the url_maker() factory method should be overridden, which provides a code reference to a routine that provides however many URLs are necessary to retrieve the data over a list of symbols within the given date range, for a particular target (quotes, dividends, splits). Different sites have different formats and different limitations on how many quotes are returned for each query. See Finance::QuoteHist::Yahoo and Finance::QuoteHist::QuoteMedia for some examples of how to do this.For more complicated sites, such as Yahoo, overriding additonal methods might be necessary for dealing with things such as splits and dividends.
