# getstockquote.pl - Retrieves stock data for given ticker symbol(s)
#
# Purpose: This script returns a nicely formatted HTML table containing stock
# data for ticker symbols given as command line arguments. This
# script can be used from a server-side exec (it's orginal use) or
# via a call from a regular CGI script. It could also be called from
# PHP, but I haven't tested this. The script prints its results on
# STDOUT.
# Usage: READ AT THE VERY END OF THIS COMMENT BLOCK
# The "quote_source" value can can any of the following:
# yahoo: NYSE quotes
# yahoo_europe: Europe quotes
# fidelity: Fidelity Investments Quotes
# troweprice: Quotes from T. Rowe Price
# vanguard: Quotes from Vanguard Group
# asx: Australian quotes from ASX
# tiaacref: Annuities from TIAA-CREF.
# Requires: Script requires at least perl 5.005, patch 3.
# Script must have the Finance::Quote module installed. This module
# in turn requires the LWP modules (which in turn have their own
# reqs). See CPAN for exact requirements for LWP:
# http://www.perl.com/CPAN-local//modules/by-module/LWP/
# Or you can simply type as root user
# perl -MCPAN -e "install Finance::Quote"
# All dependancies will be resolved automatically then

# This script has been altered by an anonymous coder to fit the Knewsticker

# Please set your stock symbols and the ticker you wish to retrieve them from
# as follows:
# Locate the Variable that is named 'my @tickers'
# within the parenthesis put as the FIRST values you ticker, for example yahoo
# or yahoo_europe or any of the others mentioned above
# any subsequent value seperated by a whitespace is a ticker symbol
# such as MSFT or IBM or LNUX
# Make sure all data is set correctly then call this script from Knewsticker
