{使用说明：
1)强的上升趋势(牛市): pdi > mdi 和 ADX≥ 30
――走势有创新高的价格时，PDI上升，MDI下降。即若PDI金叉MDI显示买进信号。
(2)强的下降趋势(熊市)：PDI < MDI 和 ADX≥ 30
――当MDI“金叉”PDI时，显示市场有新的空头卖出，因此为卖出信号。
当走势维持某种趋势时，PDI和MDI的交叉信号相当准确。（牛皮盘档时交叉则无效。）
当行情朝单方向发展时，无论涨跌势，ADX都会不断递增，当ADX大于上日，可以判断当前行情维持原势。特别是当PDA和ADX，或MDI和ADX同向上升时，表示当前涨或跌的趋势十分强劲。即ADX值若从高点转跌时，就将转势。
(3)略牛的盘整期：PDI > MDI 和 16 < ADX < 30
(4)略熊的盘整期：PDI < MDI 和16 < ADX < 30。
(5)静寂期： ADX ≤16和(PDI > MDI 或 PDI < MDI) 。
(6)在牛市ADX越大越强，但是大于60就要注意了，牛市将可能要回调。
上面的PDI你可理解成牛的力量；MDI理解成熊的力量；而ADX理解成牛熊力量对比的度量没有方向性。}
