    Default 各种技术形态分析六

    技术指标威廉指数

      威廉指数(%R)是由拉瑞?威廉于1973年的《我如何赚取百万美元》一书中首先发表的,所以以他的名字命名,原名叫威廉超买超卖指数,简称WMS%R或%R。该指数是利用摆动点来度量市场的超买超卖现象,所以可以此预测循环周期内的高和低点,找出其有效信号,是分析市场短期行情走势的技术指标。计算时先要决定周期天数,用此数取一个买卖循环的半数。许多分析家认为一个买卖循环为28天,除开周六、日,实际交易日为20天。一个较长的买卖循环期为56天,除开周六、日,交易日是40天,如各取其一半正好是10天和20天。也有取5天周期来计算%R的。

      (1)计算方法:

       WR = 100 X(H10-C10)/(H10-L10)。

       H10:10天内最高价。

       L10:10天内最低价。

       C10:10天内收盘价。

       威廉指数(%R)计算方法与强弱指数(RSI)、随机指数(KD)一样,计算出的指数值在0100之闲波动,不同的是威廉指数的值越小,市场的买气越重;反之该值越大,市场卖气越浓。

      (2)运用法则:

       (a)当%R高于80,汇率处在超卖状态,行情即将见底,80横线一般称买入线。

       (b)当%R低于20,汇率处在超买状态,行情即将见顶,20横线一般称卖出线。

       ?%R由超卖区向上攀升,表示行情可能转向,一般情况下当%R突破50中轴线时,市场由弱转强,可以追买。

       (d)当%R由超买区向下滑落,跌破50中轴线时,市场跌势加剧,可以追卖。

       (e)市场有时超买后还可以超买,超卖后还可以超卖,当%R进入超买或超卖区时,行情并非一定转势,只有%R明显转向跌破卖出线或买进线时,才是正确的买卖信号。

       (f)使用时最好能够同时配合使用相对强弱指数(RSI)来检验验证,当%R向上、向下破50中线时,也可用相对强弱指数信号是否正确,发挥两者互补功能,对行情判断有好处。

       威廉指数的设计与随机指数的原理相似,不同的是威廉指数采样天数略长,随机指数采样天数稍短,所以两者同具优缺点。

    这是我非常喜欢的指标之一,底部金叉和顶部死叉意义比较大。

    要明白什么是适合自己的方法,首先要给自己定好位置,你是想做匠还是想做师。

    指数是利用摆动点来度量市场
