它通过计算当前收盘价与一定周期前的收盘价的差值与这段时间内价格波动的范围的比值，来判断目前的股价走势是趋势还是盘整。
|

市场波动指数CMI的计算公式：
|

CMI=(Abs(Close-ref(close,(n-1)))*100/(HHV(high,n)-LLV(low,n))

其中，Abs是绝对值。

n是周期数，例如３０。
|

市场波动指数CMI的使用方法：
|
||
这个指标的重要用途是来区分目前的股价走势类型：盘整，趋势。当CMI指标小于２０时，市场走势是盘整；当CMI指标大于２０时，市场在趋势期。
|
||
CMI指标还可以用于预测股价走势类型的转变。因为物极必反，当CMI长期处于０附近，此时，股价走势很可能从盘整转为趋势；当CMI长期处于１００附近，此时，股价趋势很可能变弱，形成盘整。

"""
|
||
KDJ指标的中文名称又叫随机指标，是一个超买超卖指标,最早起源于期货市场，由乔治·莱恩（George Lane）首创。
|
||
随机指标KDJ最早是以KD指标的形式出现，而KD指标是在威廉指标的基础上发展起来的。
|
||
不过KD指标只判断股票的超买超卖的现象，在KDJ指标中则融合了移动平均线速度上的观念，形成比较准确的买卖信号依据。在实践中，K线与D线配合J线组成KDJ指标来使用。
|
||
KDJ指标在设计过程中主要是研究最高价、最低价和收盘价之间的关系，同时也融合了动量观念、强弱指标和移动平均线的一些优点。
|
||
因此，能够比较迅速、快捷、直观地研判行情，被广泛用于股市的中短期趋势分析，是期货和股票市场上最常用的技术分析工具。
|
||
|
||
第一步 计算RSV：即未成熟随机值（Raw Stochastic Value）。
|
||
RSV 指标主要用来分析市场是处于“超买”还是“超卖”状态：
|
||
- RSV高于80%时候市场即为超买状况，行情即将见顶，应当考虑出仓；
|
||
- RSV低于20%时候，市场为超卖状况，行情即将见底，此时可以考虑加仓。
|
||
N日RSV=(N日收盘价-N日内最低价）÷(N日内最高价-N日内最低价）×100%
|
||
第二步 计算K值：当日K值 = 2/3前1日K值 + 1/3当日RSV ;
|
||
第三步 计算D值：当日D值 = 2/3前1日D值 + 1/3当日K值；
|
||
第四步 计算J值：当日J值 = 3当日K值 - 2当日D值.

顺势指标又叫CCI指标，CCI指标是美国股市技术分析 家唐纳德·蓝伯特(Donald Lambert)于20世纪80年代提出的，专门测量股价、外汇或者贵金属交易
|
||
是否已超出常态分布范围。属于超买超卖类指标中较特殊的一种。波动于正无穷大和负无穷大之间。但是，又不需要以0为中轴线，这一点也和波动于正无穷大
|
||
和负无穷大的指标不同。
|
||
它最早是用于期货市场的判断，后运用于股票市场的研判，并被广泛使用。与大多数单一利用股票的收盘价、开盘价、最高价或最低价而发明出的各种技术分析
|
||
指标不同，CCI指标是根据统计学原理，引进价格与固定期间的股价平均区间的偏离程度的概念，强调股价平均绝对偏差在股市技术分析中的重要性，是一种比
|
||
较独特的技术指标。
|
||
它与其他超买超卖型指标又有自己比较独特之处。象KDJ、W%R等大多数超买超卖型指标都有“0-100”上下界限，因此，它们对待一般常态行情的研判比较适用
|
||
，而对于那些短期内暴涨暴跌的股票的价格走势时，就可能会发生指标钝化的现象。而CCI指标却是波动于正无穷大到负无穷大之间，因此不会出现指标钝化现
|
||
象，这样就有利于投资者更好地研判行情，特别是那些短期内暴涨暴跌的非常态行情。
