This Sunday, 25th 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 21:00 GMT to Fridays at 21:00 GMT, the change to summertime means that market will again open at the normal time of 23:00 for Western European Traders. In Europe clocks will be set back to wintertime on Sunday 4th November 2018.
