Many traders struggle with the decision of using one strategy all the time . The real situation lies in knowing how to differentiate the present market condition you are trading in for an instance A moving average based system may work very well in a trending market but fail in a range bound market. At the same time a Stochastic might give you great signals in a range bound market but result in many false signals in a trending market. The key is to decide which market you are going to trade. If you are going to trade a trending market, pick the appropriate strategy and stick to it and likewise for a range bound market.
