How using Ask and Bid inside a for-loop?

for(int s=14400;s>1;s--){       
         for(int t=0;t<21;t++){
           h_cur=High[s+t];
           if(h_cur>highest)
               highest=h_cur; 
         }
         for(int y=0;y<21;y++){
           l_cur=Low[s+y];
           if(l_cur<lowest)
               lowest=l_cur; 
         } 
            if((Ask>highest)&&(Open[0]<highest)&&(flag!=1)){
               currentcross=Ask; 
               resulttable[a][b][0]=currentcross-previouscross; 
               time=TimeToStr(Time[s],TIME_DATE|TIME_MINUTES);
               hour=TimeHour(Time[s]);
               flag=1;
               previouscross=currentcross;
               profit=resulttable[a][b][0];
               Print("  Tid ",time,"  PIP ",profit,"  Hour ",hour,"  Number ",b);
               b++;
            }
            if((Bid<lowest)&&(Open[0]>lowest)&&(flag!=2)){
               currentcross=Bid;
               resulttable[a][b][0]=-currentcross+previouscross;
               time=TimeToStr(Time[s],TIME_DATE|TIME_MINUTES);
               hour=TimeHour(Time[s]);
               flag=2;
               previouscross=currentcross;
               profit=resulttable[a][b][0];
               Print("  Tid ",time,"  PIP ",profit,"  Hour ",hour,"  Number ",b);           
               b++;
            }
            highest=0;
            lowest=0;  
            Sleep(100);
       }
}

This is the code I´m using. Is there a problem using Ask and Bid inside a for-loop? "if((Ask>highest)...". It works in an EA with the Strategy tester but not with a code used for printing. The reason I want to print it is because I want to collect some statistics.
