以变色KDJ公式中画向上红箭头时为条件编写一个选股公式

编写条件：

VAR1:=(H+L+O+C*2)/5; VAR2:=EMA(VAR1,21); VAR3:=STD(VAR1,23); VAR4:=EMA(VAR1,2); VARA:=(VAR1-VAR2)*100/VAR3; K:(EMA(VARA,23)+100)/2-3,COLOR00FFFF,LINETHICK2; D:SMA(K,5,1),COLORFFFF00,LINETHICK2; J:4*K-3*D,COLORFF00FF,LINETHICK2; IF(J>REF(J,1),J,DRAWNULL),COLORRED,LINETHICK2; IF(JREF(J,1)AND JREF(VAR4,1) AND K>=REF(K,1)AND J<40 OR CROSS(J,K)AND CROSS(J,D) AND J<40 OR J>REF(J,1)AND J<-20,7), J*0.8,1); DRAWICON(FILTER(J<=REF(J,1) AND J>80,8), J*1.2,2); 图片上传出错，先谢谢老师帮助！

编写方法：

&nbsp;VAR1:=(H+L+O+C*2)/5;

VAR2:=EMA(VAR1,21);

VAR3:=STD(VAR1,23);

VAR4:=EMA(VAR1,2);

VARA:=(VAR1-VAR2)*100/VAR3;

K:=(EMA(VARA,23)+100)/2-3;

D:=SMA(K,5,1);

J:=4*K-3*D;

FILTER(J>REF(J,1)AND J<REF(J,3)

AND J<K AND VAR4>REF(VAR4,1)

AND K>=REF(K,1)AND J<40

OR crOSS(J,K)AND CROSS(J,D) 

AND J<40 OR J>REF(J,1)AND J<-20,7);
