macd零下二次金叉的选股公式

编写要求：

以下是一个macd零下二次金叉的指标源码，请老师改一下，能实现零下的、第二次金叉的选股公式。非常感激，谢谢。 SQX:=(C-MA(CLOSE,13))*100; DIFF:EMA(MA(SQX,7),1),COLOR00FFFF; DEA:EMA(DIFF,7),COLORFF33FF; MACD:(DIFF-DEA)*2,COLORSTICK; 低位金叉:IF(CROSS(DIFF,DEA) AND DIFF=0)); 二次金叉:IF(CROSS(DIFF,DEA) AND DEACLOSE AND DIFF>REF(DIFF,A1+1) AND CROSS(DIFF,DEA),10,0),COLORRED; DRAWLINE(A1=0,DEA,底背离,DEA,0),COLORRED,LINETHICK2; A2:=BARSLAST(REF(CROSS(DEA,DIFF),1)); 顶背离:REF(CLOSE,A2+1)DIFF AND CROSS(DEA,DIFF),COLORGREEN; DRAWLINE(A2=0,DEA,顶背离,DEA,0),COLORGREEN,LINETHICK2; A3:=CROSS(DIFF,DEA) AND DEA

股票网解答：

SQX:=(C-MA(CLOSE,13))*100;

DIFF:=EMA(MA(SQX,7),1);

DEA:=EMA(DIFF,7);

A3:=CROSS(DIFF,DEA) AND DEA<0;

零下二次金叉:FILTER(COUNT(A3,21)=2,10);
