=head1 NAME

Finance::Quote::Sinvestor - Obtain quotes from S-Investor platform.

=head1 SYNOPSIS

    use Finance::Quote;

    $q = Finance::Quote->new;
    or
    $q = Finance::Quote->new('Sinvestor', 'sinvestor' => {INST_ID => 'your institute id'});

    %info = Finance::Quote->fetch("Sinvestor", "DE000ENAG999");  # Only query Sinvestor
    %info = Finance::Quote->fetch("europe", "brd");     # Failover to other sources OK.

=head1 DESCRIPTION

This module fetches information from https://s-investor.de/, the investment platform
of the German Sparkasse banking group. It fetches share prices from various online
and physical exchanges, and fund prices from the investment companies. The source
is returned in the "exchange" field.

Suitable for shares, ETFs and funds that are traded in Germany.

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

This module provides "Sinvestor" and "europe" fetch methods.

Information obtained by this module may be covered by s-investor.de terms and
conditions.

=head1 INST_ID

https://s-investor.de/ supports different institute IDs. The default value "0000057" is
used (Krefeld) if no institute ID is provided. A list of institute IDs is provided here:
https://web.s-investor.de/app/webauswahl.jsp

The INST_ID may be set by providing a module specific hash to
Finance::Quote->new as in the above example (optional).

=head1 LABELS RETURNED

The following labels are returned:
currency
