原理解析：
VAR1赋值:收盘价-30日前的收盘价的绝对值
VAR2赋值:SUM(收盘价-1日前的收盘价的绝对值,30)
VAR3赋值:VAR1/VAR2
VAR4赋值:VAR3*(0.8-2/24)+2/24
VAR5赋值:VAR4*VAR4
输出AMA2:ED收盘价的VAR5日简单移动平均,2),画绿色,LINETHICK1
输出牛熊分水岭:AMA2,STICK,COLORGRAY
VAR10:=C>牛熊分水岭 AND 牛熊分水岭>1日前的牛熊分水岭
VAR11:=C<牛熊分水岭 AND 牛熊分水岭<=1日前的牛熊分水岭
输出AMA3:IF(AMA2/1日前的AMA2>0.997,AMA2,DRAWNULL), 画蓝色,LINETHICK1
输出AMA4:IF(AMA2/1日前的AMA2>1.001,AMA2,DRAWNULL),画红色,LINETHICK1
