Can you tell me how to find the absolute maximum and minimum on the history with the strategy tester?
Maximum and minimum of what?

Maximum and minimum of what?

In the history of EURUSD, the maximum and minimum prices of the day. The time of their formation.

EURUSD history maximum and minimum prices for the day. The time of their formation.
Read iHighest and iLowest

Read iHighest and iLowest

Finding through iHighest and iLowest is not a problem. How to bake this into the tester so that it gives information on formation time, on a particular history.

You can try it this way:

 for (int i=0; i<iBars(Symbol(),PERIOD_D1); i++) {
  double HistoryMaximum=iHigh(Symbol(),PERIOD_D1,i);
  double HistoryMinimum=iLow(Symbol(),PERIOD_D1,i);
  Print("Дата ",TimeToStr(iTime(Symbol(),PERIOD_D1,i),TIME_DATE)," Максимум=",DoubleToStr(HistoryMaximum,Digits)," Минимум=",DoubleToStr(HistoryMinimum,Digits));
 }

You could try it this way:


How can I make the minimum and maximum times be displayed separately? Or rather, it is not a problem. There are several lines for each time in the logbook.

What could be the problem? How to make one line output per value. Ideally, you want a time in numbers that can be copied into excel and compared by

match.

Again, my delete pending orders function does not delete everything. Moreover, it doesn't delete everything in the tester. Help me to understand what is wrong with it.

void DeletePendingOrders()
{
    int numberOfTry = 0,
        err,
        ticket;

   for (int i=OrdersTotal()-1; i>=0; i--)
   {
      if (!OrderSelect(i, SELECT_BY_POS, MODE_TRADES)) continue;
      if (OrderMagicNumber() != i_magic) continue;
      if (OrderSymbol() != Symbol()) continue;
      if (OrderType() > 1 && OrderType() < 6)
      {
         ticket = OrderTicket();
         numberOfTry = 0;
      
         while (numberOfTry < 3)
         {
            while (!IsTradeAllowed()) Sleep(5000);
                err = 0;

           if (OrderDelete(ticket, Red))
            {
                numberOfTry = 3;
            }
            else
            {
                err = GetLastError();
                Print("err = ", err);
            }
      
            if (err > 0)
            { 
              Print(numberOfTry," #",ticket," Error modifing order: (", err , ") ");
              Sleep(5000); RefreshRates(); numberOfTry++;
            }
         }
      }
   }
}

and compare it by coincidence.



Here's the script, writes the data to a file. Extremes to the nearest minute for the whole story:

int start() {
 int Handle=FileOpen("ScriptDayExtr",FILE_WRITE|FILE_CSV);
 if(Handle<0) {Print("Ошибка создания файла"); return(0);}
 datetime TimeMax,TimeMin;
 double HistoryMaximum=0;
 double HistoryMinimum=99999999.9;
 int LastH=TimeHour(iTime(Symbol(),PERIOD_M1,0));
 Print("Баров в истории ",iBars(Symbol(),PERIOD_M1)," т.е всего на ",DoubleToStr(iBars(Symbol(),PERIOD_M1)/60.0/24.0,2)," дней");
 for (int i=iBars(Symbol(),PERIOD_M1)-1; i>=0; i--) {
  if(iTime(Symbol(),PERIOD_M1,i)==0) {Print("ERROR");continue;}
  int H=TimeHour(iTime(Symbol(),PERIOD_M1,i));
  if(H<LastH && TimeMax>0){
  FileWrite(Handle," Максимум=",DoubleToStr(HistoryMaximum,Digits)," случился в ",TimeToStr(TimeMax,TIME_DATE|TIME_MINUTES),"             ",
        " Минимум=",DoubleToStr(HistoryMinimum,Digits)," случился в ",TimeToStr(TimeMin,TIME_DATE|TIME_MINUTES));
  HistoryMaximum=0;
  HistoryMinimum=99999999999999.9;
  }
  LastH=H;
  if( iHigh(Symbol(),PERIOD_M1,i)>HistoryMaximum) {HistoryMaximum=iHigh(Symbol(),PERIOD_M1,i);TimeMax=iTime(Symbol(),PERIOD_M1,i);}
  if( iLow(Symbol(),PERIOD_M1,i)<HistoryMinimum)  {HistoryMinimum=iLow (Symbol(),PERIOD_M1,i);TimeMin=iTime(Symbol(),PERIOD_M1,i);}
 }
 FileClose(Handle);
 return(0); 
 }


And to make it in the tester - an indicator has to be written however.
