加速指标（AC）是从动量震荡指标（AO）与其5日移动平均线值之间差值的5日移动平均线值得来的。通过将一系列所得结果组成柱状图能 准确的发现当前动量速度的变化。因为AC先于AO，而AO又先于价格，所以比尔·威廉姆称观察该指标的变化就像阅读后天的《华尔街日报》。 在交易软件中柱线图分为红绿两种颜色，它们围绕一根零轴线运动。当最新的一根柱线高于前一根柱线时它就是绿色的，相反，当最新的 一根柱线低于前一根柱线时它就是红色的。AC能产生三种买入信号和三种卖出信号：
1、在零轴线以上一根红柱线低于前一根红柱线，随后出现了两根绿柱线，第二根绿柱线就是买入信号；
2、在零轴线以下一根红柱线随后出现了三根绿柱线，第三根绿柱线就是买入信号；
3、一根红柱线低于前一根红柱线，随后出现了两根绿柱线，第二根绿柱线从下向上穿越零轴线产生了买入信号；
4、在零轴线以下一根绿柱线高于前一根绿柱线，随后出现了两根红柱线，第二根红柱线就是卖出信号；
5、在零轴线以上一根绿柱线随后出现了三根红柱线，第三根红柱线就是卖出信号；
6、一根绿柱线高于前一根绿柱线，随后出现了两根红柱线，第二根红柱线从上向下穿越零轴线产生了卖出信号。

AO用法：
1、在零轴线以上最新的绿柱线出现在红柱线之后就产生了碟型买入信号；
2、最新的柱线从下向上穿越零轴线时就产生了穿越买入信号；
3、在零轴线以下最新的峰值高于前一个峰值并出现了一个绿柱线就产生了双峰买入信号；
4、在零轴线以下最新的红柱线出现在绿柱线之后就产生了碟型卖出信号；
5、最新的柱线从上向下穿越零轴线时就产生了穿越卖出信号；
6、在零轴线以上最新的峰值低于前一个峰值并出现了一个红柱线就产生了双峰卖出信号。
