（盗用一下壹瓣杺埖老师所说的“自适应均线”这个概念）
这个指标是根据已知来预测未来的，所以只是参考。
指标表面上只有一两条均线，但却是有玄机的。

{股海网提供：www.guhai.com.cn}
简单说一下指标的原理：
下图是一张用未来函数ZIG找出的股票前期波段高低点。
  

试想如果有这么一条均线，前期（我指定为D=8天以前）的两个低点（或更多）在该均线处都受到支撑，即它经过点1、点2或点3，那么可以认为下一次股价回调到该均线时，将受到一定程度的支撑，如果支撑失败股价跌破该均线，则认为该均线将成为压力线。
       我的目的便是找到这样的一条均线，以D天前的高低点为‘依据点’，如果周期为T的一条均线经过前期的‘依据点’最多，则画出该周期T的均线，EMA（C，T）。其中周期T是是会根据情况自动调整的，也就是说画出的均线会自动调整到最佳。
如果同时有两条或两条以上均线有相同多个‘依据点’，则会自动画出两条或两条以上的均线。
当然，当股价盘整走势时，有时画出的均线并不具有参考价值。而且为了说明方法，我举的例子是比较理想的。

上图是将均线附上去后的主图，图中的小人头是指假设小人头位置是最近一日的K线（通过调节D可以移动小人头，观察以前的均线情况）。上图图中的均线经过1、3两点，在图中小人头标记的那天，我们可以预测下一个支撑位5以及后面的压力位6' 。
