=head1 NAME

Finance::Quote::XETRA - Obtain quotes from XETRA/XFRA.

=head1 SYNOPSIS

use Finance::Quote;

$q = Finance::Quote->new;

%info = Finance::Quote->fetch("xetra", "EU0009658145.XETR");

=head1 DESCRIPTION

This module fetches information from the XETRA and XFRA exchange, also including ETFs.

The desired exchange can be specified by appending 'XETR' or 'XFRA' after the ISIN,
separating the two with a dot '.' (see synopsys).

The full list of available symbols can be found at
https://www.xetra.com/xetra-de/instrumente/alle-handelbaren-instrumente

This module is loaded by default on a Finance::Quote object. It's also possible
to load it explicitly by placing "XETRA" in the argument list to
Finance::Quote->new().

This module provides the "xetra" fetch method.

=head1 LABELS RETURNED

The following labels may be returned by Finance::Quote::XETRA :
exchange symbol last high low isodate date close currency
