Hi Andre,
We don't currently offer any Scandinavian exchanges at the moment and
can't make any guarantees that OSE or other exchanges will be covered.
You can see all of the exchanges we currently offer quotes for at
http://www.google.com/intl/en-US/help/stock_disclaimer.html.
That said, we do have plans to continue to expand our coverage of
international markets. Hopefully we'll be able to include them in the
future :)
Cheers,
A
