I have a system that I have been trading for a few months. The entries are a certain distance from the Asian market open on a Tuesday on the GBPUSD. I generally don't trade through holiday periods but was wondering if the start of the New Year was a ok time to get back in. Does anyone find that the first week of the year has any different behavior? Alternatively does anyone find that the day after a long weekend or a public holiday exhibits any different price behavior to normal? Do holiday periods track sideways due to many participants not trading?
