session about safe? I do not think there is a safe session ... all sessions have always had the same risk, whether the session asia, europe and america.
It also depends on who we traded pairs, if we are related to trading europe and america, asia then in session tends to move slowly ... moving slowly does not mean safe, but it may be easier in the predictions.
but because it pairs each have their uniqueness, then I do not think there is a safe session. To be safe, you should be ready with the stop loss. stop loss is better than mc.
