主题：记录最高最低价错误

if barstatus=1 then begin
 highprice := high;
 lowprice := low;
 position := 0;
end

highprice:=max(h,ref(highprice,1));
lowprice:=min(l,ref(lowprice,1)); 

 
最高:highprice;
最低:lowprice;

上面是代码，我想记录从图标上第一根到当前bar的最高最低价，上面这段代码问题出在哪？

INPUT:N(3),MAXHOLD(1)
if barstatus=1 then begin
 highprice := high;
 lowprice := low;
 position := 0;
end

//refhigh:= ref(close,1),linethick0;
//refhigh: ref(highprice,1);

highprice:=max(h,ref(highprice,1));
lowprice:=min(l,ref(lowprice,1)); 

aaaa:barstatus,linethick0;
最高:highprice;
最低:lowprice;

//开多开空
if holding<=0 and h>=lowprice*(1+n/100) then begin
 buy(holding<=0,1,LIMITR,lowprice*(1+n/100));
 highprice:=h;
end

if holding>=0 and l<=highprice*(1-(n+0.1)/100) then begin
 BUYSHORT(holding>=0,1,LIMITR,highprice*(1-(n+0.1)/100));
 lowprice:=low;
end

//加多加空
buy(holding>0 and holding<maxhold and high>=ENTERPRICE*(1+n/100),1,LIMITR,ENTERPRICE*(1+n/100));
BUYSHORT(holding<0 and holding>0-maxhold and l<ENTERPRICE*(1-(n+0.1)/100),1,LIMITR,ENTERPRICE*(1-(n+0.1)/100));

持仓:HOLDING,linethick0;
