I will definitely put this into consideration when I begin trading forex. It is necessary to focus on avoiding trading in the morning as you said too because that is the time when a lot of traders are just trying their luck without having a key strategy to depend on.The early hours of any trading day is usually very volatile, I have seen enough to make this claim. Then Mondays are particularly hostile too as big news from the weekend always affect trades. Friday is also volatile since some persons would be trying to make quick profits for the weekend.
