选出来的不是昨天大于四的阴线被今天大于四的阳线覆盖的K线组合。
Y1:=C/OPEN>1.04;{阳线４％}
RY2:=REF(OPEN,1)/REF(CLOSE,1)>1.04;{阴线４％}
RY3:=ABS(OPEN-REF(C,1))<C*0.02 AND ABS(C-REF(OPEN,1))<C*0.02;{两线相等}
X4:DRAWTEXT(RY1 AND RY2 AND RY3 ,LOW,'日月合璧'),COLORYELLOW;
RY2:=REF(OPEN,1)/REF(CLOSE,1)>1.04;{阴线４％}
RY3:=ABS(OPEN-REF(C,1))<C*0.02 AND ABS(C-REF(OPEN,1))<C*0.02;{两线相等}
X4:DRAWTEXT(RY1 AND RY2 AND RY3 ,LOW,'日月合璧'),COLORYELLOW;
解答如下：
RY1:=C/OPEN>1.04;{阳线４％}
RY2:=REF(OPEN,1)/REF(CLOSE,1)>1.04;{阴线４％}
RY1>NOT(RY2);
RY2:=REF(OPEN,1)/REF(CLOSE,1)>1.04;{阴线４％}
RY1>NOT(RY2);
