請教：

N:=7;
Z1:=STRCAT(HYBLOCK,'?');
Z2:=STRCAT(Z1,DYBLOCK);
Z3:=STRCAT(Z2,'?');
DRAWTEXTEX(ISLASTBAR,0,0,0,STRCAT(Z3,GNBLOCK)),COLOR00C0C0;
A1:=REF(H,N)=HHV(H,2*N+1);
B1:=FILTER(A1,N);
C1:=BACKSET(B1,N+1);
D1:=FILTER(C1,N);
A2:=REF(L,N)=LLV(L,2*N+1);
B2:=FILTER(A2,N);
C2:=BACKSET(B2,N+1);
D2:=FILTER(C2,N);
E1:=(REF(LLV(L,2*N),1)+REF(HHV(H,2*N),1))/2;
E2:=(H+L)/2;
H1:=(D1?AND?NOT(D2?AND?E1>=E2))?OR?ISLASTBAR?OR?BARSCOUNT(C)=1;
L1:=(D2?AND?NOT(D1?AND?E1<E2));
H2:=D1?AND?NOT(D2?AND?E1>=E2);
X1:=REF(BARSLAST(H1),1)+1;
F1:=BACKSET(H1?AND?COUNT(L1,X1)>0,LLVBARS(IF(L1,L,10000),X1));
G1:=F1>REF(F1,1);
I1:=BACKSET(G1,2);

這個是其他軟件里顯示的線
