㈠ 求布林帶,布林極限和布林極限寬指標公式
1)%BB=(自close-lower band)÷(upper band-lower band)
布林極限公式:
參數描述: 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)
布林極限寬公式:
參數描述: 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;
