公式

RVIorig = 100*( EMA[W14] of U)/( EMA[W14] of S)

RVI = (RVIorig of highs + RVIorig of lows)/2, where


S = Stddev (10 days) - 为期10天的标准偏差;

U = S, 如果目前的价格比前一时期的价格高;

U = 0, 如果目前的价格比前一时期的价格低;

EMA (w14) = 14天期间指数移动平均线;

RVIorig of highs - 相对活力指数高点;

RVIorig of low - 相对活力指数低点.

RVI的主要优点是,它是基于RSI指标,并考虑所有RSI可能省略的水平的多样化。然而,RVI是不稳定的指标,但不是经典振荡器,这就是为什么独立使用它是不合理的。作为推论,结合RVI信号和技术分析的振荡器信号更好,例如,RSI指标。

RSI指标与RVI一起进入超卖区克服70%的情况下,我们会收到一个强有力的信号,价格爬升将很快结束,并开始降低。

此外,如果RSI和RVI指标低于30%的水平,换句话说,进入超买区,有必要准备价格突进。根据这一点,结合使用这两个指标比单独使用要更好。

当RSI超过70%或低于30%,但RVI没有确认这些信号,最好是开仓前等他们都将显示出类似的图像。

运用RVI的另一种选择是价格的发散和收敛鉴定。如果价格正在上升,而该指数正在下降,这表明,价格将很快下降(发散的情况下)。

相反的情况也是真实的:指数下降,而价格的增长,这象征着价格加速(收敛的情况下)。

这些信号形成与当RVI处于超买或超卖区有关。但即使RVI指数进入中性区(30%-70%之间),发散/收敛信号也将表明。

考虑到RVI认为比RSI指标较大规模的参数,在RVI的帮助下,接收到的信号将更好。
