推荐一不错波段公式：波段超买超卖，提供选股

RSV:=(CLOSE-LLV(LOW,8))/(HHV(HIGH,8)-LLV(LOW,8))*100;
GS0:SMA(RSV,3,1),COLORRED,LINETHICK1; GS1:SMA(GS0,3,1),COLORYELLOW,LINETHICK1;
RSV1:=(CLOSE-LLV(LOW,38))/(HHV(HIGH,38)-LLV(LOW,38))*100;
GS2:SMA(RSV1,5,1),COLORFF00FF,LINETHICK1;
GS3:SMA(GS2,10,1),COLORGREEN,LINETHICK1;
超卖:18,COLORWHITE;
超买:85,COLORBLUE;
STICKLINE(GS0 GS1,GS0,GS1,1,0),COLORRED;
STICKLINE(GS0 =GS1,GS0,GS1,1,0),COLORYELLOW;
STICKLINE(GS2 GS3,GS2,GS3,1,0),COLORFF00FF;
STICKLINE(GS2 =GS3,GS2,GS3,1,0),COLORGREEN;
红色与粉红色同时出现区域选股。
RSV:=(CLOSE-LLV(LOW,8))/(HHV(HIGH,8)-LLV(LOW,8))*100;
GS0:=SMA(RSV,3,1);
GS1:=SMA(GS0,3,1);
RSV1:=(CLOSE-LLV(LOW,38))/(HHV(HIGH,38)-LLV(LOW,38))*100;
GS2:=SMA(RSV1,5,1);
GS3:=SMA(GS2,10,1);
XG:CROSS(GS0 GS1 AND GS2 GS3,0.5);
