把该指标修改成图中指南针—样

A:=VOL*CLOSE; B:=SUM(A,1)/SUM(VOL,1); B1:=EMA(B,17); 主力:(B-B1)*100/B,COLORRED; 进:STICKLINE(主力>=0 AND 0>=REF(0,1),0,主力,１,0),COLORRED; 出:STICKLINE(主力=REF(0,1),0,主力,１,0),COLORGREEN;

爱约股解答：

A:=VOL*CLOSE;

B:=SUM(A,1)/SUM(VOL,1); 

B1:=EMA(B,17); 

主力:=(B-B1)*100/B;

DRAWBAND(主力,RGB(250,80,80),0,RGB(0,180,180));
