cut loss is not easy because it should cut loss should not be the only thing stopping the movement of prices, also use stop loss so if you can not cut loss also may still exercise for cut loss, remains exposed to MC but hit SL. in addition there is a daily profit target, there should be a daily risk tolerance. So suppose target profit about 30 pips a day, then the target loss is tolerated there must also suppose 50 pips. If one of the target is triggered and the need to learn discipline, do not trade that day.
