资金流动指数指标(MFI)
资金流动指数指标(MFI)

技术指标资金流量指数(MFI)指示投资于证券的资金密度。其构造和解释与相对强弱指数类似,唯一的不同是MFI考虑交易量。

分析资金流量指数时请谨记:

指标与价格变动之间的背离。如果价格上涨而资金流量指标下跌(反之亦然),价格反转的可能性极高;

资金流量指数高于80和低于20的值预警市场潜在的顶部和底部。

计算

资金流量指数的计算包括多个步骤。第一步是定义周期内的代表价格(TP):

TP = (HIGH + LOW + CLOSE)/3

然后计算资金流总额(MF):

MF = TP * VOLUME

如果今天的代表价格高于昨天的TP,则认为资金流为正。如果今天的代表价格低于昨天的,资金流为负。

正资金流是选定时期内正资金流的总和。负资金流是选定时期内负资金流的总和。

然后用正资金流除以负资金流计算资金比率(MR):

MR = Positive Money Flow (PMF)/Negative Money Flow (NMF)

最后,使用资金比率计算资金流指数:

MFI = 100 - (100 / (1 + MR))
