Absolutely you are correct talking about the different trading session gives us different opportunities. I have experienced on it. While I trades all day trading I have seen its very much true. It seems to me that US session is one of the best session in online trading market, because during this session market looks very active and if we trades seriously and confidently, we must take some good profit money from it. in the world the different markets open in the different time and have different movements some has quick movements and some has slow movements and the traders can get different income so market has different sessions for trading
