The Copenhagen Stock Exchange has become the latest exchange to implement Computershare technology to carry out surveillance on its market.

Computershare has already sold technology to other exchanges in the Norex alliance, of which the Copenhagen Stock Exchange is part. Last month, Stockholmsbörsen, the Swedish stock exchange, agreed to use the software, along with Oslo Børs, the Norwegian stock exchange. Iceland is now the only exchange in the Norex alliance that is not using the software.
