分享一个简单实用的附图 趋势抄底，是老前辈发明的

这个测试了大半年了，简单好用，不晕人，我直接上代码了，省得大家在支付下载，希望大家拿回去共同改进

VAR2:=(CLOSE-LLV(LOW,20))/(HHV(HIGH,20)-LLV(LOW,20))*100;
 VAR3:=SMA(SMA(VAR2,3,1),3,1)/30;
 VAR4:=EMA(VAR3,5);
 VAR5:=3*VAR3-2*VAR4;
 AA:=CROSS(VAR5,VAR3) AND VAR3<2.1 AND C>O;
 VAR6:=(2*CLOSE+HIGH+LOW)/4;
 VAR7:=LLV(LOW,22);
 VAR8:=HHV(HIGH,22);
 VAR9:=EMA((VAR6-VAR7)/(VAR8-VAR7)*100,13);
 VARA:=EMA(0.667*REF(VAR9,1)+0.333*VAR9,2);
 STICKLINE(VAR9>VARA,VAR9,VARA,1,1), COLORMAGENTA;
 STICKLINE(VAR9<=VARA,VAR9,VARA,1,1), COLORFFCC66;
 STICKLINE(CROSS(VAR5,VAR3) AND VAR3<2.1 AND C>O,VAR9,VARA,1,0),COLORRED;
 DRAWTEXT(CROSS(VAR5,VAR3) AND VAR3<2.1 AND C>O,22,'底'),COLORYELLOW;
趋势: EMA(0.382*REF(VAR9,2)+0.618*VAR9,6);
 IF(趋势>REF(趋势,1),趋势,DRAWNULL),COLORRED,LINETHICK2;
 IF(趋势 风险较高:80,COLORRED;
获利可抛:50,COLORWHITE;
抄底区:20,COLORGREEN;

以下为条件选股公式：

VAR2:=(CLOSE-LLV(LOW,20))/(HHV(HIGH,20)-LLV(LOW,20))*100;
 VAR3:=SMA(SMA(VAR2,3,1),3,1)/28.57;
 VAR4:=EMA(VAR3,5);
 VAR5:=3*VAR3-2*VAR4;
选股:CROSS(VAR5,VAR3) AND VAR3<2.1 AND C>O;
