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。
