抄底和逃顶是股民永远的追求，波段操作是套取利润最好的手段！那么，能不能用最简单的办法去跟踪股价波段走势，从而抄底逃顶波段操作呢？请看下图！
VAR1:=(CLOSE-LLV(LOW,36))/(HHV(HIGH,36)-LLV(LOW,36))*100;
VAR2:=SMA(VAR1,3,1);
VAR3:=SMA(VAR2,3,1);
VAR4:=SMA(VAR3,3,1);
波: VAR3;
段: VAR4;
VAR6:=CROSS(VAR3,VAR4) AND VAR3<20;
DRAWTEXT(FILTER(VAR6,10)=1,40,'抄底'),COLORRED;
VAR7:=CROSS(VAR4,VAR3) AND VAR3>80;
DRAWTEXT(FILTER(VAR7,5)=1,60,'逃顶'),COLORGREEN;
STICKLINE(VAR3>=VAR4,VAR3,VAR4,2,0),COLORRED;
STICKLINE(VAR3<VAR4,VAR3,VAR4,2,0),COLORGREEN;
