学习笔记丨CCI使用技巧
今天分享的技术指标是CCI（商品通道指数），又称顺势指标。可能没有BOLL和KDJ那么有名，但是最近发现用的人也不少，学习一下，以此记录。
一、什么是CCI指标
CCI虽然最初是为商品交易设计的，但是也适用于股票市场，CCI假设市场是有周期性的，通过测量股价与其统计平均值的偏离程度，来寻找超买/超卖的时机。
相比起别的指标，比如KDJ，CCI指标没有范围的限制，理论上可以无限大或无限小，偏离程度越大，CCI的绝对值越高。
二、CCI指标怎么算
CCI的计算分为四步，通常以14天（N=14）为标准周期：
1、计算典型价格 (Typical Price, TP)
CCI 不只看收盘价，它综合了当天的最高价、最低价和收盘价，以获得更全面的价格代表性。
2、计算TP的N日简单移动平均 (MA)
计算过去N个周期（如 14 天）的TP平均值。
3、计算平均绝对偏差 (Mean Deviation, MD)
4、计算CCI
分子表示当前价格与过去平均价格的距离。如果分子很大，说明价格正在快速偏离过去一段时间的平均水平。
分母中的0.015是一个调节系数，作用是将数值“缩放”到常用的尺度。如果没有这个常数，CCI 的数值可能会非常小，不便于在图表上观察。
三、CCI指标怎么用
1、CCI的常态区间在±100之间。
2、突破信号：当CCI从下向上突破+100，买入信号；从上向下跌破-100，卖出信号。
3、回归信号：当CCI在+100之上运行很久，向下跌破+100，可能是见顶回调的信号；当 CCI 在-100之下运行很久，向上突破 -100，股价可能反弹。
4、背离信号： 股价创新高，但CCI指标的峰值一个比一个低。这预示着上涨动力衰减，随时可能反转下跌；股价创新低，但CCI指标的谷值一个比一个高。这说明下跌动能枯竭，可能迎来反弹。
四、总结
1、衡量偏差
和BOLL一样，CCI的数学原理也是统计学中衡量“偏离均值”的办法，只不过BOLL用的就是标准差，CCI用的是MD，虽然计算方法略有不同，但它们描述的是同一件事：当前的波动是不是比平时更猛？
2、滞后性
和绝大多数的技术指标一样，指标的计算都依赖于历史数据，这说明这些指标一定是滞后的。
所以在实际交易中，如果教条的、单一的去看待这些指标是必死无疑的。所有的指标都是参考，指标会欺骗你。
那指标就没用了吗？我并不觉得，被海外市场过去这么多年的实盘验证过的东西，如果没用早就被淘汰了，既然能用，自然有价值，只是也不能迷信这玩意儿，可以不信，但肯定不能全信。
