文华wh6期货波浪顶底连线黄金分割自动画线指标公式

还在手动标记波段高低点画分割线吗？这套文华财经自动画线源码可自动识别N周期极值，直接输出 0.382‑0.5‑0.618 关键分割位置。代码用到 BACKSET 未来函数，信号会重绘，仅供源码学习参考，切勿直接拿来实操。后果自负。

N:=10;
高:=H>HV(H,N),NODRAW;
高N:=BARSLAST(高)+1;
低:=L<LV(L,N),NODRAW;
低N:=BARSLAST(低)+1;
高A:=BACKSET(COUNT(低,高N)&&低,高N);
低A:=BACKSET(COUNT(高,低N)&&高,低N);
DRAWLINE1(CROSS(高A=1,0.5),H,CROSS(低A=1,0.5),L,0),LINETHICK1,COLORGREEN;
DRAWLINE1(CROSS(低A=1,0.5),L,CROSS(高A=1,0.5),H,0),LINETHICK1,COLORRED;

DRAWLINE3(ISLASTBAR&&BARSLAST(CROSS(高A=1,0.5))<BARSLAST(CROSS(低A=1,0.5)),L,0,1,REF(H,BARSLAST(CROSS(高A=1,0.5))),BARSLAST(CROSS(高A=1,0.5)),0),COLORGREEN,DOT;
DRAWLINE3(ISLASTBAR&&BARSLAST(CROSS(高A=1,0.5))>BARSLAST(CROSS(低A=1,0.5)),H,0,1,REF(L,BARSLAST(CROSS(低A=1,0.5))),BARSLAST(CROSS(低A=1,0.5)),0),COLORRED,DOT;
