BOLL简单指标

编写一个BOLL简单指标

爱约股解答：

N:=20;

MID:=MA(C,N);

VART1:=POW((C-MID),2);

VART2:=MA(VART1,N);

VART3:=SQRT(VART2);

UPPER:=MID+2*VART3;

LOWER:=MID-2*VART3;

BOLL:REF(MID,1),COLORFFFFFF;

UB:REF(UPPER,1),COLOR00FFFF;

LB:REF(LOWER,1),COLORFF00FF;

AA:=(UB-LLV(UB,20))/(HHV(UB,20)-LLV(UB,20));

CC:=(LB-LLV(LB,20))/(HHV(LB,20)-LLV(LB,20));

DD:=CROSS(MA(UB,5),UB) AND HHV(AA,3)>=0.98;

EE:=CROSS(MA(LB,5),REF(MA(LB,5),1)) AND LLV(CC,3)<=0.1 AND HHV(C,3)>BOLL;
