波段操作是很多朋友的爱好，也是我的心头所好。现以副图指标波段妙手与大家分享。
{波段妙手}
VAR1:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;
VAR2:=SMA(VAR1,3,1);
VAR3:=SMA(VAR2,3,1);
VAR4:=3*VAR2-2*VAR3;
波段线:VAR2,COLORWHITE;
趋势线:VAR3,COLORYELLOW;
STICKLINE(VAR4>REF(VAR4,1),VAR4,REF(VAR4,1),2,0),COLORRED;
STICKLINE(VAR4<REF(VAR4,1),VAR4,REF(VAR4,1),2,0),COLORGREEN;
DRAWICON(CROSS(VAR2,VAR3) AND VAR3<20,VAR3,1);
DRAWICON(CROSS(VAR3,VAR2) AND VAR3>80,VAR3,2);
