All fellow users outside N.America are kindly reminded that this weekend most parts of USA and Canada move to Daylight Saving Time (clocks are set forward). This is three weeks earlier then it had been in the past.
So if you are on Central European Time (eg. Frankfurt, DE) and are used to US market opening at 15:30 your local time, it will open on Monday Mar-12 at 14:30. Ref: http://www.timeanddate.com/time/dstevents.html
