精准买卖信号指标 说明：本指标是通达信MACD精准买卖指标公式。在原指标的基础上我增加了选股公式，顶底及中轴，并引入了均线系统(在指标的底部出现，由红，白，绿三色组成，它的含义是红色多头，绿色空头，白色为过渡区或叫观望区）。通过加入了这些元素，比较方便选股和看盘。
本指标实际上是macd和kdj的合成版本，比较以前的类似版本，界面清爽了许多。
macd历来有指标之王之美称，深入地研究它，正确地使用它，是制胜的关键。
其具体如何操作，这个问题比较复杂，我一时也讲不清楚，请谅解。只讲一点：0轴上方是否有红柱是判断多空的一个重要标志，它是多空博弈的结果。
请多关注上升趋势的股票，回避下降趋势的股票，能做到这点，那你就成功了一半。
当macd上拐等于1时即为选股，另外一个选股公式是蓝，红，黄（牛熊三色）同时有数据显示时也是选股。这些选股公式给出的选股结果及红绿箭头出现的买卖点仅供参考，不作为投资的依据。如何买卖还得参考大盘因素，成交量和其它指标综合研判。
本指标无未来函数。
