| Subject: | Module for Bucharest Stock Exchange (BSE) |
Hi,
I've created a module for the Bucharest Stock Exchange stocks. As I'm
not very good in Perl, I've based it on the Athens Stock Exchange module.
I've tested the code with the attached tester (self-made) and with
GnuCash and it works fine.
This code does have a minor problem though - the module name is seen as
"bsero" (no caps) instead of "BSERO" as I would expect. I couldn't find
the problem, but I consider it minor. If you have the time, perhaps you
can look into it.
Thanks,
Andrei Cipu

=head1 NAME
Finance::Quote::BSERO Obtain quotes from Bucharest Stock Exchange.
=head1 SYNOPSIS
use Finance::Quote;
$q = Finance::Quote->new;
%info = Finance::Quote->fetch("bsero","tlv"); # Only query BSERO
%info = Finance::Quote->fetch("romania","brd"); # Failover to other sources OK.
=head1 DESCRIPTION
This module fetches information from the "Bucharest Stock Exchange"
(Bursa de Valori Bucuresti), http://www.bvb.ro. All stocks are available.
This module is loaded by default on a Finance::Quote object. It's
also possible to load it explicity by placing "BSERO" in the argument
list to Finance::Quote->new().
This module provides both the "bsero" and "romania" fetch methods.
Please use the "romania" fetch method if you wish to have failover
with future sources for Romanian stocks. Using the "bsero" method will
guarantee that your information only comes from the Bucharest Stock Exchange.
Information obtained by this module may be covered by www.bvb.go
terms and conditions See http://www.bvb.ro/ for details.
=head1 LABELS RETURNED
The following labels may be returned by Finance::Quote::BSERO :
name, last, date, p_change, open, high, low, close,
volume, currency, method, exchange.
