Oslo Stock Exchange (Norwegian: Oslo Børs) serves as the main market for trading in shares of Norwegian companies. It opens 9:00 and closes 16.30 local time (CET). In additional to a wide range of domestic companies, OSE attracts a lot of international companies within petroleum, shipping and other related areas.

Oslo Stock Exchange started its life as Christiania Børs in 1819. In the beginning, there was no organized listing or stock exchange; the Børs served as a meeting place for investors auctioning ships, shares in ships, commodities, and foreign currencies. Stocks and bonds only started trading on the exchange in 1881.

In 1988, the exchange introduced electronic trading support system, and replaced the old auction model with continuous trading of listed shares throughout the day. Trading became fully electronic in 1999 and the trading floor was discontinued.
