网友求助：
各位老大根据以下这段主图源码帮忙做出前三、 四、五、六的高低画线源码，谢谢！

前一低: REF(LOW,BARSLAST(J38)),ColorWHITE,PointDot,Linethick3;
前二低: REF(LOW,BARSLAST(J3A)),Colormagenta,PointDot,Linethick2;
前一高: REF(HIGH,BARSLAST(J3C)),ColorWHITE,PointDot,Linethick3;
前二高: REF(HIGH,BARSLAST(J3E)),Colormagenta,PointDot,Linethick2;
解答如下：
原来公式有点罗嗦了，可以这样
input:N(5);
J1:=BARSTATUS=2;
J2:=REF(HIGH,N)=HHV(HIGH,2*N+1);
J3:=FILTER(J2,N);
J4:=BACKSET(J3,N+1);
J5:=FILTER(J4,N);
J6:=J5 OR J1;
J7:=REF(LOW,N)=LLV(LOW,2*N+1);
J8:=FILTER(J7,N);
J9:=BACKSET(J8,N+1);
JA:=FILTER(J9,N);
JB:=JA AND NOT(J5);
HORILINE(J6,h,J6 ),Colorffffff,DOTLINE; 高参考:ref(ref(h,BARSLAST(J6)),1),Linethick0;
HORILINE(JB,l,JB ),Color00ffff,DOTLINE; 低参考:ref(ref(l,BARSLAST(Jb)),1),Linethick0;
选股和预计用高参考，低参考
