过我研究，看先40以上的反转比较可靠，和80以上的逃顶，大家可以修改一下源码里边的数值！
{波段操作}
VAR1:=(CLOSE-LLV(LOW,20))/(HHV(HIGH,20)-LLV(LOW,20))*100;
VAR2:=SMA(VAR1,3,1);
VAR3:=SMA(VAR2,3,1);
VAR4:=3*VAR2-2*VAR3;
VAR5:=LLV(LOW,30);
VAR6:=HHV(HIGH,30);
VAR7:=EMA((CLOSE-VAR5)/(VAR6-VAR5)*100,5);
VAR8:=EMA(0.667*REF(VAR7,1)+0.333*VAR7,2);
波段买入:IF(CROSS(VAR7,VAR8) AND VAR7<20,50,0),COLORRED,LINETHICK2;
波段卖出:IF(CROSS(VAR8,VAR7) AND VAR7>80,50,0),COLORGREEN,LINETHICK2;
DRAWTEXT(波段买入,40,'买'),COLORRED;
DRAWTEXT(波段卖出,40,'卖'),COLORGREEN;
