麻烦老师弄个画线指标 (文华财经WH6赢顺V6.7)

这里使用ZIGZAG函数判断波峰可以参考：

GD:=H=ZIGZAG(H,3,1)&&H>REF(H,1);

A:=BACKSET(ISLASTBAR,SUMBARS(GD,1));

B:=BACKSET(ISLASTBAR,SUMBARS(GD,2));

DRAWLINE1(CROSS(A,0.5)||CROSS(B,0.5),H,CROSS(A,0.5)||CROSS(B,0.5),H,1);

DD:=L=ZIGZAG(L,3,1)&&L>REF(L,1);

A1:=BACKSET(ISLASTBAR,SUMBARS(DD,1));

B1:=BACKSET(ISLASTBAR,SUMBARS(DD,2));

DRAWLINE1(CROSS(A1,0.5)||CROSS(B1,0.5),L,CROSS(A1,0.5)||CROSS(B1,0.5),L,1);
