I was reading Bain's blog and want to mention some of what he wrote because I have had similar observations.  This information, for those of you have been trading forex for a while may be more common knowledge at this point.  

Peter simply states that forex traders should be aware of the clock due to price swings associated with certain times of the day.   These swing points can be noticed most often during the following:

1. London open (3 am EST or 8:00 GMT)
2. London close (10:30 am EST - 12:00 Noon EST or 15:30 GMT - 17:00 GMT)
3. New York open (8:00 am EST or 13:00 GMT)

Swing points are most evident when London is opening, in session, or closing due to London's majority in Forex trading volume.  

I've always said if I were ever to trade forex full-time, it would most certainly be during the hours of 3am EST (London Open) and 12 Noon EST (London close).  Outside of these times, things can be pretty low a majority of the time.
