kD过滤指标介绍
kD过滤指标
KD是大家最常用的指标，然而其也常常产生无效的交叉信号，这和波动的幅度有着密切的关系，从此思路考虑设计了该指标，抛砖引玉了！
KD过滤指标
n(9,3,100);
m1(3,2,10);
m2(3,2,10);
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<SJ1,DD,GD),NODRAW;
{(通达信用NODRAW，大智慧一类用linethick0）;}
IF(SJ<SJ1,DD,DRAWNULL),COLORRED,CIRCLEDOT;
IF(SJ>SJ1,GD,DRAWNULL),COLORGREEN,CIRCLEDOT;
KD的交叉是否有效要看红绿灯！
