在《完全换手2》公式中增加前数5，前量5，前数6，前量6的表达

编写要求：

以下是求助老师编写的《完全换手2》，我想在此基础上增加前数5，前量5，前数6，前量6的表达，（见附图两红线）几次编写均未成功，再次求助老师帮助，谢谢啦！HS:V*100/FINANCE(7)*100,VOLSTICK;HS1:=INTPART(SUM(HS/100,0));HS2:=HS1!=REF(HS1,1) OR BARSCOUNT(C)=0;HS3:=BARSLAST(HS2);HS4:=SUM(HS,HS3+1);S2:=REF(HS3,HS3+1);S3:=REF(REF(HS3,HS3+1),HS3+1);S4:=REF(REF(REF(HS3,HS3+1),HS3+1),HS3+1);Q1:=BACKSET(ISLASTBAR,HS3+1);Q2:=BACKSET(ISLASTBAR,S2+HS3+2);Q3:=BACKSET(ISLASTBAR,S3+S2+HS3+3);Q4:=BACKSET(ISLASTBAR,S4+S3+S2+HS3+4);前数1:IF(Q1>0,BARSLAST(Q1>REF(Q1,1))+1,DRAWNULL),NODRAW,COLORYELLOW;前量1:IF(Q1>0,SUM(HS,前数1),DRAWNULL),COLORYELLOW;前数2:IF(Q2>0,BARSLAST(Q2>REF(Q2,1))+1,DRAWNULL),NODRAW,COLORGREEN;前量2:IF(Q2>0,SUM(HS,前数2),DRAWNULL),COLORGREEN;前数3:IF(Q3>0,BARSLAST(Q3>REF(Q3,1))+1,DRAWNULL),NODRAW,COLORMAGENTA;前量3:IF(Q3>0,SUM(HS,前数3),DRAWNULL),COLORMAGENTA;前数4:IF(Q4>0,BARSLAST(Q4>REF(Q4,1))+1,DRAWNULL),NODRAW,COLORBLUE;前量4:IF(Q4>0,SUM(HS,前数4),DRAWNULL),COLORBLUE;STICKLINE(HS2,HS,0,2,0),COLORMAGENTA;DRAWICON(HS2,0,3);AA:=CONST(HHV(HS,120))*0.6;DRAWTEXT(CROSS(HS4,25),AA,'25％'),COLORYELLOW;DRAWTEXT(CROSS(HS4,50),AA,'50％'),COLORYELLOW;DRAWTEXT(CROSS(HS4,75),AA,'75％'),COLORYELLOW;DRAWTEXT(HS2,AA,'100％'),COLORMAGENTA;STICKLINE(CROSS(HS4,25) OR CROSS(HS4,50) OR CROSS(HS4,75),HS,0,0,0),COLORYELLOW;DRAWTEXT(Q1>REF(Q1,1),AA/2,'1次'),COLORYELLOW;DRAWTEXT(Q2>REF(Q2,1),AA/2,'2次'),COLORGREEN;DRAWTEXT(Q3>REF(Q3,1),AA/2,'3次'),COLORMAGENTA;DRAWTEXT(Q4>REF(Q4,1),AA/2,'4次'),COLORBLUE;

解答：

 Q2:=BACKSET(ISLASTBAR,S2+HS3+2);
