布林线选股公式

1、布林线中轨向上或走平股价接触到下轨的公式：MID:=MA(C,20);VART1:=POW((C-MID),2);VART2:=MA(VART1,20);VART3:=SQRT(VART2);UPPER:=MID+2*VART3;LOWER:=MID-2*VART3;BOLL:=REF(MID,1);LB:=REF(LOWER,1);XG:BOLL>=REF(BOLL,1)ANDC<=LB;

2、布林线中轨向上或走平，股价接触到中轨的公式：MID:=MA(C,20);VART1:=POW((C-MID),2);VART2:=MA(VART1,20);VART3:=SQRT(VART2);UPPER:=MID+2*VART3;LOWER:=MID-2*VART3;BOLL:=REF(MID,1);LB:=REF(LOWER,1);XG:BOLL>=REF(BOLL,1)ANDC<=BOLL;

3、布林线中轨向下或走平，股价接触到下轨的公式：MID:=MA(C,20);VART1:=POW((C-MID),2);VART2:=MA(VART1,20);VART3:=SQRT(VART2);UPPER:=MID+2*VART3;LOWER:=MID-2*VART3;BOLL:=REF(MID,1);LB:=REF(LOWER,1);XG:BOLL<=REF(BOLL,1)ANDC<=LB;
