如何在日线图里标示出上周最高价,并在该处画一直线,并只显示最近周期,谢谢!!!

w:barslast(datediff(ref(date,1),date)<>weekday-ref(weekday,1) or barpos=1),linethick0;
//w1:barslast(w>0 and refx(w,1)=0),linethick0;
//vertline(w1=0),pointdot;
ww:sumbars(w=0,2),linethick0;
hw:ref(hhv(ref(H,1),ww-1),w),linethick0;
partline(barpos>datacount-ww[datacount]+1,hw[datacount]);

谢谢kkkkkk 兄!!!
