主题：[求助]老师帮忙编写一个模型！

hh:=ref(hhv(h,30),todaybar);
ll:=ref(llv(l,30),todaybar);
cc:=ref(c,todaybar);
maxrange:=max((hh-cc),(cc-ll));
dayrange:=hh-ll;
if maxrange=hh-cc and todaybar=1 and maxrange/dayrange>=0.6 then buy(holding=0,1,marketr);
if maxrange=cc-ll and todaybar=1 and maxrange/dayrange>=0.6 then buyshort(holding=0,1,marketr);

if time0>=timetot0(closetime(0))-60 then begin
 sell(1,0,marketr);
 sellshort(1,0,marketr);
end

不太对是靠感觉的吗？能否实际举一个例子说明是不对的？
