This Sunday, 29th of March, clocks will be set forward by one hour in many countries of the northern hemisphere. While there is no change in the Dukascopy opening hours from Sundays at 21:00GMT to Fridays at 21:00 GMT, the change to summertime means that market will again open at the normal time of 11pm for Western European Traders. In Europe clocks will be set back to wintertime on Sunday 28 October 2015.
