大资金波段主图

**大资金模型**

市场中的大资金通常被称为鲸鱼。 鲸鱼可以对各种市场的价格走势产生重大影响。 因此，如何监测鲸鱼走势，无论从哪方面都具有重要意义。

**大资金波段主图**
为了更直接地了解大资金，发布了一个大资金模型应用于主图表，作为不同颜色的蜡烛，以及分别以黄色、紫红色和浅绿色显示的短期、中期、长期移动平均线。 大资金模型是由一条快线EMA2，一条慢线EMA42用xsl(close,21))*(20)+close人工曲线拟合而成，其中xsl用于计算数据序列的斜率。 然后，根据黄金交叉和死交叉状态的定义，大资金行为可以提取为绿色蜡烛看涨，红色蜡烛看跌。 同时，一种新型的黄色蜡烛被定义为代表看涨摆动的开始。
