If you want to trade with them beware that there is a clone entity named Dukascopi using the same address as the actual Dukascopy broker. However, the real Dukascopy is regulated by the Swiss Financial Market Supervisory Authority (FINMA) both as a bank and a securities dealer, while the clone is, unsurprisingly, registered in the offshore zone St. Vincent and the Grenadines.

Always double-check the information received by the broker you want to work with! Don’t trust blindly, always make sure that you’re working with a legitimate company.
