㈠ 求布林带,布林极限和布林极限宽指标公式
1)%BB=(自close-lower band)÷(upper band-lower band)
布林极限公式:
参数描述: N(1,100,20), P(1,10,2)
MID := MA(CLOSE,N);
UPPER:= MID + P*STD(C,N);
LOWER:= MID - P*STD(C,N);
BB:(C-LOWER)/(UPPER-LOWER),COLORWHITE;
(2)Band width=(upper band-lower band)÷average(n)
布林极限宽公式:
参数描述: N(1,100,20), P(1,10,2)
MID := MA(CLOSE,N);
UPPER:= MID + P*STD(C,N);
LOWER:= MID - P*STD(C,N);
BWIDTH:(UPPER-LOWER)/MID,COLORWHITE;
