# 推力指数 (Force Index)

推力指数技术指标由 Alexander Elder 开发。该指数在每次递增时测量牛势力度，并在递减时测量熊势力度。它与最基本的市场信息要素相挂钩: 价格趋势，暴跌，和业务交易量。此指数可以按照原样使用, 但是最好使用 [移动均线](https://www.metatrader5.com/zh/mobile-trading/iphone/help/chart/indicators/trend_indicators/moving_average) 进行近似。使用短线移动均线逼近 (作者建议使用间隔 2) 有助于发现开仓和平仓的最佳时机。如果使用长线移动均线 (周期 13) 进行逼近, 则指数体现出趋势变化。

- 在指标上涨趋势的周期中，当指数变为负值时 (跌落低于零)，最好买入;
- 当它升到一个新峰值时，指数发出上涨趋势会持续的信号;
- 当指数在下降趋势期间变为正值时，卖出信号到来;
- 当指数下降到一个深度时，它标志着熊势力度，且下跌趋势将持续;
- 如果价格的变化与相应的交易量变化相不能匹配的话，推力指数仍旧保持在一个水平上，这就告诉您趋势很快就会变化。

## 计算

每个行情走势的推动力都是以其方向，比例和交易量为特征的。如果当前柱线的收盘价高于前一根，推力指数为正值。如果当前柱线的收盘价低于前一根，推力指数为负值。价格差异越大, 推力越大。交易量越大, 推力越大。

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

其中:

FORCE INDEX (i) ― 当前柱线的推力指数;
VOLUME (i) ― 当前柱线的交易量;
MA (ApPRICE, N, i) ― 当前柱线的任意 N 周期 [移动均线](https://www.metatrader5.com/zh/mobile-trading/iphone/help/chart/indicators/trend_indicators/moving_average):

ApPRICE ― 应用价格;
N ― 周期平滑;
MA (ApPRICE, N, i-1) ― 之前柱线的[任意移动均线](https://www.metatrader5.com/zh/mobile-trading/iphone/help/chart/indicators/trend_indicators/moving_average)。
