如果您相信技术分析中“趋势是您的朋友”的信条,那么移动平均线将使您获益匪浅。移动平均线显示在特定周期内某一特定时间的平均价格。它们被称作“移动”,因为它们依照同一时间度量,且反映最新平均线。移动平均线的不足之一在于它们滞后于市场,因此并不一定能作为趋势转变的标志。为解决这一问题,使用5or10The shorter period moving average of days will be lower than40or200The moving average of the day better reflects recent price trends. Alternatively, the moving average can also be used by combining two different time span averages. Regardless of use5and21The moving average of the day, or40and200天的移动平均线,买入信号通常在较短期平均线向上穿过较长期平均线时被查觉。与此相反,卖出信号会在较短期平均线向下穿过较长周期平均线时被提示。
