股票网解答：

网友求助：

DIFF 和 DEA 露出水面（ 0 轴上）后：
第一次形成死叉，标记 ❶ 第二次形成死叉，标记❷ ，第三次形成死叉，标记❸；
第一次形成金叉，标记①，第二次形成死叉，标记② ，第三次形成死叉，标记③；
谢谢！

 

解答如下：

{0轴上}
DIF:=EMA(CLOSE,12)-EMA(CLOSE,26);
DEA:=EMA(DIF,9);
A:=SUM(CROSS(DIF,DEA) AND DIF>0 AND DEA>0,BARSLAST(MAX(DIF,DEA)<0)+1);
B:=SUM(CROSS(DEA,DIF) AND DIF>0 AND DEA>0,BARSLAST(MAX(DIF,DEA)<0)+1);
DRAWTEXT(CROSS(B,0.5),H*1.02,'①'),COLORGREEN;
DRAWTEXT(CROSS(B,1.5),H*1.02,'②'),COLORGREEN;
DRAWTEXT(CROSS(B,2.5),H*1.02,'③'),COLORGREEN;
DRAWTEXT(CROSS(A,0.5),L/1.02,'①'),COLORMAGENTA;
DRAWTEXT(CROSS(A,1.5),L/1.02,'②'),COLORMAGENTA;
DRAWTEXT(CROSS(A,2.5),L/1.02,'③'),COLORMAGENTA;

{0轴下}
DIF:=EMA(CLOSE,12)-EMA(CLOSE,26);
DEA:=EMA(DIF,9);
A:=SUM(CROSS(DIF,DEA) AND DIF<0 AND DEA<0,BARSLAST(MIN(DIF,DEA)>0)+1);
B:=SUM(CROSS(DEA,DIF) AND DIF<0 AND DEA<0,BARSLAST(MIN(DIF,DEA)>0)+1);
DRAWTEXT(CROSS(B,0.5),H*1.02,'①'),COLORGREEN;
DRAWTEXT(CROSS(B,1.5),H*1.02,'②'),COLORGREEN;
DRAWTEXT(CROSS(B,2.5),H*1.02,'③'),COLORGREEN;
DRAWTEXT(CROSS(A,0.5),L/1.02,'①'),COLORMAGENTA;
DRAWTEXT(CROSS(A,1.5),L/1.02,'②'),COLORMAGENTA;
DRAWTEXT(CROSS(A,2.5),L/1.02,'③'),COLORMAGENTA;
