没想到大家和我一样喜欢MACD实站指标，非常感谢，再把我改的飞狐特SE主图鳄鱼-线献给大家，有不完美的地方，希望老师帮修改一下，如上影线和下影线粗，我没改过来，圆点应为箭头。
   公式用法：该指标是根据【浑沌操作法】一书的原理编写而来。
指标中的红箭头，并非买入信号，而是股价向上突破前一个碎型高点。
指标中的绿箭头，并非卖出信号，而是股价向下突破前一个碎型低点。
指标里的红、绿、蓝三线走势如鳄鱼，因此称之为『鳄鱼线』。
当该三条线多头排列时，指标解盘中称之为“鳄鱼线向上张口”为多头趋势。
当该三条线空头排列时，指标解盘中称之为“鳄鱼线向下张口”为空头趋势。
当指标不断出现红箭头，说明多头趋势在延续，指标不断出现绿箭头时，说明空头趋势在延续，当之前持续出红箭头后，再出现绿箭头时，谨防趋势反转，反之亦然。
