以下是通达信波段K线（多空线的变化）
想法：副图的多空线，变为主图指标。（可以参考下方已有指标。可在这个指标的基础上改。也可写新的。）
指标见截图。
金叉向上，dkx 或madkx 上升角度超过20度。两线为绿色。线粗2。
dkx 或madkx 上升角度小于20度，不变色。两线为白色.线粗1。
死叉向下，两线为红色。线粗2
其它条件。
绿色必须经过一次金叉底部的抬高。
也就是二次金叉股价必须大于一次金叉股价。（不好写，也可以不写）
也可以加入其它必要条件。比如ma20>ma30 and ma30>ma60 ,此时的双绿，才更有操作机会。
变色k线部分，可保留，也可去除。
如有疑问，可以留言。
