强力指数 - FRC
强力指数 - FRC

技术指标强力指数(FRC)衡量多头力量的每一次增加和空头力量的每一次减少。它连接市场信息的主要元素:价格趋势、趋势变化和交易量。该指标可以独立使用,但最好将其用移动平均进行平滑。买卖的最佳时刻可用短期移动平均轻松确定。如果是使用长期移动平均(例如13个单位周期)进行平滑,指数可透露趋势改变。

在上行的强力指数变负(跌过零线)的时候买进;

指标创新高预示上涨趋势的延续;

在下行的强力指数变正时卖出;

强力指数形成新低谷预警空头加强和下跌趋势的延续;

如果价格变化没有交易量同样变化的确认,强力指数将保持在同一水平。这是趋势反转即将发生的信号。

计算

市场每一次变动的力量都有方向、规模和交易量的特征。如果当期收盘价高于前一期,力量为正。如果当期收盘价低于前一期,力量为负。价格差距越大,力量越强。交易量越大,力量越强。

FORCE INDEX (i) = VOLUME (i) * ((MA (ApPRICE, N, i) - MA (ApPRICE, N, i-1))

其中:

FORCE INDEX (i) - 当期强力指数;

VOLUME (i) - 当期交易量;

MA (ApPRICE, N, i) - 当期的N期移动平均;

简单、指数、加权或平滑;

ApPRICE - 应用价格;

N - 平滑周期;

MA (ApPRICE, N, i-1) - 前期移动平均。
