The Nasdaq Copenhagen, formerly known as the Copenhagen Stock Exchange (Danish: Københavns Fondsbørs), is an international marketplace for Danish securities, including shares, bonds, treasury bills and notes, and financial futures and options.

In 1997 the FUTOP Clearing Center A/S, the Danish derivatives market, became a wholly owned subsidiary.

FUTOP issues, clears, and guarantees futures and options on shares, indices, and interest rate products.

In 1998, the CSE and the Stockholmsbörsen formed the NOREX Alliance, a step toward developing a Nordic securities market.

Normal trading sessions are from 09:00am to 05:00pm on all days of the week except Saturdays, Sundays and holidays declared by the exchange in advance.
