Stochastic Oscillator indicator formula and settings
随机震荡技术指标对当前收盘价与一个特定时期的价格范围进行比较。该指标由两条线表示。主线称为%K线。第二条线称为%D线，它是%K线的移动平均。%K线通常由实线表示，而%D线通常是虚线。
解释随机震荡指标有三种最流行的方法。
- 当指标(%K线或%D线之一)下降至特定水平(常用20)并且上升超过该水平时买入。当指标上升至特定水平(常用80)并且下降至低于该水平时卖出；
- 当%K线升至%D线以上时买入。当%K线低于%D线时卖出；
- 追踪背离。举例：价格形成一系列新高但随机震荡指标无法突破之前的高度。
计算
随机震荡指标有四个变量：
- %K线周期。它是用于随机指标计算的周期数目；
- %K线慢周期。该值控制%K线的平滑程度。值为1代表着快随机；值为3可看作慢随机；
- %D线周期。它是用于计算%K线移动平均的周期数目；
- %D线方法。它是用于计算%D线的方法(即指数、简单、平滑、或加权)。
计算%K线的公式为：
%K = (CLOSE-LOW(%K))/(HIGH(%K)-LOW(%K))*100
其中：
CLOSE - 当日收盘价；
LOW(%K) - %K线周期中最低的最低价；
HIGH(%K) - %K线周期中最高的最高价。
移动平均%D线根据下面公式计算：
%D = SMA(%K, N)
其中：
N - 平滑周期；
SMA - 简单移动平均。
