KD是大家最常用的指標(biāo)，然而其也常常產(chǎn)生無效的交叉信號，這和波動的幅度有著密切的關(guān)系，從此思路考慮設(shè)計了該指標(biāo)，拋磚引玉了！

N:=9;M1:=3;M2:=3;
RSV:=(CLOSE-LLV(LOW,N))/(HHV(HIGH,N)-LLV(LOW,N))*100;
K:SMA(RSV,M1,1),LINETHICK2;
D:SMA(K,M2,1),LINETHICK2,COLORRED;
BDL:=MA(ABS(K-REF(K,1)),10);
DD:=LLV(K,N)+BDL,DOTLINE;
GD:=HHV(K,N)-BDL,DOTLINE;
SJ:=BARSLAST(CROSS(K,GD));
SJ1:=BARSLAST(CROSS(DD,K));
GLX:IF(SJ IF(SJ IF(SJ>SJ1,GD,DRAWNULL),COLORGREEN,CIRCLEDOT;
