编写条件：
可视范围最高:=hhvall(h)=h; h1:=if(可视范围最高,h,0); hh:=if(h=h1,0,h); 可视范围次高:=hhvall(hh)=h; 压力:DRAWLINE(可视范围最高, h,可视范围次高,h,1),LINETHICK1,Color79A5FF; 可视范围最低:=llvall(l)=l; l1:=if(可视范围最低,l,0); ll:=if(l=l1,0,l); 可视范围次低:=llvall(ll)=l; 支撑:DRAWLINE(可视范围最低, l,可视范围次低,l,1),LINETHICK1,Coloryellow; 求助老师修改一下压力位和支撑位主图，我的主图怎么有压缩？请老师帮忙一下。编写方法：
{视窗画线}
