2、dma指标参数设置多少
dm化顾载依女植政说希杂a指标参数设置是什么：
1、DIF：收盘价的N1日简单移动平均行夜谈曾是-收盘价的N2日简单移动平均
2、AMA=DIF的M日简单移动剧者争取席平均
3、参数N1为10，参数N2为50，参数M为6
3、dma指标参数设置技巧
其实很简单的。DMA指标利用两条不同期间的平均线，计算差值之后，再除以基期天数。它是两条基期不同平均线的差值，由于其是将短期均线与长期均线进行了协调，也就是说它滤去了短期的随机变化和长期的迟缓滞后，使得其数值能更准确、真实、客观地反映股价趋势。故它是一种反映趋势的指标应用法则：
① DMA是两条基期不同平均线差值。实线向上交叉虚线，买进。
② 实线向下交叉虚线，卖出。
③ DMA 也可观察与股价的背离。
