為什麽這個選股公式沒有未來函數，但指標會漂移呢，如何修改呢？

AAA2:=SUM(IF( O>REF(O,1),VOL*O,0),0);

AAA3:=SUM(IF( O<REF(O,1),VOL*O,0),0);

AAA4:=SUM(IF( O=REF(O,1),VOL*O,0),0);

MAC5:=(ATAN((MA(O,5)/REF(MA(O,5),1)-1)*100)*180/3.1415926);

MM5:=MA(MAC5,5);

AMA:=PLOYLINE(CROSS(MAC5,MM5),MM5);

AAB:=PLOYLINE(CROSS(MM5,MAC5),MAC5);

買入漲:=COUNT(CROSS(MAC5,MM5),AMA<REF(AMA,5) AND AAB>REF(AAB,5));

DRAWICON(買入漲,L*0.985,9);
