你1楼的3就是下面的n，你试着把参数n调大就可以了

A1:=REF(HIGH,n)=HHV(HIGH,2*n+1); B1:=FILTER(A1,n); C1:=BACKSET(B1,n+1); D1:=FILTER(C1,n);{高点}

A2:=REF(LOW,n)=LLV(LOW,2*n+1); B2:=FILTER(A2,n); C2:=BACKSET(B2,n+1); D2:=FILTER(C2,n);{低点}

E1:=(REF(LLV(LOW,2*n),1)+REF(HHV(HIGH,2*n),1))/2; E2:=(HIGH+LOW)/2;{高低点出现在同一K线上时可作取舍}

H1:=(D1 AND NOT(D2 AND E1>=E2)) OR ISLASTBAR OR BARSCOUNT(CLOSE)=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,LOW,10000),X1));

G1:=F1>REF(F1,1); I1:=BACKSET(G1,2); LD:=I1>REF(I1,1);{过滤后低点}

L2:=LD OR ISLASTBAR OR BARSCOUNT(CLOSE)=1;

X2:=REF(BARSLAST(L2),1)+1; F2:=BACKSET(L2 AND COUNT(H2,X2)>0,HHVBARS(IF(H2,HIGH,0),X2));

G2:=F2>REF(F2,1); I2:=BACKSET(G2,2); HD:=I2>REF(I2,1);{过滤后高点}

DRAWLINE(LD,L,HD,H,0),COLORRED,LINETHICK1;

DRAWLINE(HD,H,LD,L,0),COLORGREEN,LINETHICK1;

J1:=BACKSET(ISLASTBAR,MIN(BARSLAST(HD),BARSLAST(LD))+1); J2:=J1>REF(J1,1);

DRAWLINE(J2,IF(HD,H,L),ISLASTBAR,IF(BARSLAST(HD)>BARSLAST(LD),H,L),0),COLORYELLOW,LINETHICK1;
