macd水上二次金叉公式
原理解析：
输出买:收盘价10%的之字转向>1日前的收盘价10%的之字转向 AND 1日前的收盘价10%的之字转向2日前的收盘价10%的之字转向,COLORF0F000
当满足条件买时,在1.3位置书写文字,画红色
当满足条件卖时,在1.3位置书写文字,COLOR80FF00
输出DIFF:收盘价的15日指数移动平均-收盘价的89日指数移动平均,画白色,线宽为1
输出DEA:DIFF的9日指数移动平均,画黄色,线宽为1
输出平滑异同平均:3*(DIFF-DEA), COLORSTICK,线宽为1
低位金叉赋值:DIFF上穿DEA AND DIFF=0距今天数日中满足DIFF上穿DEA的天数,线宽为4
二次金叉赋值:DIFF上穿DEA AND DEA收盘价 AND DIFF>A1+1日前的DIFF AND DIFF上穿DEA
当满足条件底背离时,在0和0.03位置之间画柱状线,宽度为6,0不为0则画空心柱.,COLOR00FF00
当满足条件A1=0时,在DEA位置画直线起点，当满足条件底背离时,在DEA位置画直线终点,0表示是否延长.,画红色,线宽为3
当满足条件底背离时,在0.12位置书写文字,COLORFF00FF
A2赋值:上次1日前的DEA上穿DIFF距今天数
顶背离赋值:A2+1日前的收盘价DIFF AND DEA上穿DIFF
当满足条件A2=0时,在DEA位置画直线起点，当满足条件顶背离时,在DEA位置画直线终点,0表示是否延长.,画绿色,线宽为3
当满足条件收阳线时,在横轴0.01纵轴0.9位置书写文字,画红色
当满足条件收阳线时,在横轴1纵轴1位置书写文字,画红色
