公式编写说明：
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(J<REF(J,1),J,DRAWNULL)COLOR00BB00,LINETHICK2;DRAWICON(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<40OR 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！
公式源码回答：
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);
