原理解析：
输出DIFF:收盘价的12日指数移动平均-收盘价的26日指数移动平均
输出DEA:DIFF的9日指数移动平均
输出MACD:2*(DIFF-DEA),NODRAW
当满足条件MACD>=0时,在MACD和0之间画柱状线
当满足条件MACD<0时,在MACD和0之间画柱状线
STICKLINE(MACD<1日前的MACDAND MACD>0,0,MACD,4,0 ),COLOR00AAFF
如果DF<0返回DIFF否则返回0
如果DF<0返回0否则返回DIFF
如果DF如果DF>DEA返回DEA否则返回DEA

JCCOUNT赋值:COUNT(DIFF上穿DEA,上次DEA>=0距今天数)
二次金叉赋值:DIFF上穿DEA AND DEA<0 AND 统计21日满足JC=2的天数=1
当满足条件二次金叉时,在DEA*0.96和DEA*0.76之间画柱状线
当满足条件二次金叉时,在DEA*1.1和'BUY'之间画图标
当满足条件二次金叉时,在DEA*0.96和'二次金叉'位置书写文字
A1赋值:上次1日前的DIFF上穿DEA距今天数
底背离赋值:A1+1日前的收盘价>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DEA*1.09和DEA*0.86之间画柱状线
DRAWLINE(A1=0,DEA,底背离,DEA,0),画红色,LINETHICK0
