I've been surprized by the Asian session many times also.
I find that if the London and N.Y. sessions are dead/choppy, then we'll usually have a good Asian session. If only someone would tell me in advance which session(s) will be the most boring so I know which one to sleep through!
Yesterday was a GREAT day, and today is turning out to be very profitable also!
I hope it stays like this for the rest of the year. If so, it will be a very merry christmas.
Good Trading,
Sundance
