MACD威利策略
Author: 雨幕（youquant）, Date: 2022-06-02 15:31:23Tags: MACDEMA
该策略主要针对倒卖/盘中交易制定。它可能被用来识别短期期权交易的进入/退出信号。当使用常规会话条数据在5分钟到15分钟的时间范围内使用时，它在热门股票上表现良好。它结合了3个流行的指标，EMA、MACD和William%range，以生成长信号和短信号。
-
EMA： 默认值为200 EMA线。
-
MACD： 快/慢信号输入的默认长度为12/26。
-
William%R-平滑（已发布）： 这是一个自定义指标，从原始William%R线生成两条移动平均线。
工作原理：
-
进入条件： 1、均线上方/下方收盘时的多头/空头进场 2、MACD线高于/低于信号线时的多/空进入（多头直方图>0，空头直方图<0） 3、William%R快速MA线高于/低于慢速MA线时的多/空进入
-
退出条件： 1、当MACD线低于信号线时，退出多头，反之亦然，退出空头。 2、当William%R fast MA line低于slow MA line时，退出多头，反之亦然，退出空头。 3、当William%R fast MA line必须在超买（-20）限额以下时多头退出，当超卖（-80）限额以上时空头退出。
请注意，未针对任何特定股票/工具优化参数
享受~~！！
