Quote from Spydertrader:
Begin to think in terms of Dominos Falling and mentally watch them fall as you anticipate the future as it moves into the Now. Price breaking higher on increasing black PRV would then continue to move higher. A change intra-bar would first manefest itself when Price moved off its extreme forming a 'spike' bar, and next creating an Intra-bar Gaussian shift, and then, if Price continued to move opposite of its original direction, Price would break the opposite extreme - creating an
Outside Bar. Volume continuing to increase while Price moves opposite of the dominant Volume represnts one of the first dominos of change. Follow the dominos from there.
