You finally got i mentioned before? Don't trade in Asia/Europe market, those markets have no life (they alway the weak and dumb followers from US market) and always sideway, it is a big NO markets to trend / momentum traders.
Also, don't trade in the 1st hour in the US market if you trade momentum, too many fake trends and reverse in the first hour. It is a common occurance and phenomenon (you will know what I mean if you ever work in pit, I will not share this info why this happen in public forum)
