mfe & mae calculation

Hi,

I like to get candles highs & lows to calculate mfe&mae. I have written a script wich is getiing trade infos from history after magic number and symbol. The script is working properly until the code arrives to get the candle highs&lows.

Here is the code, I have a problem with

for ...

I am printing out the variables and I see difference between counter2 and bar_number[0]. In the bar_number array are the closed trades bar numbers wich I get from the closed trades opening time with iBarShift.

counter1=1;
   bar_high=0; //I give value to get later the max high and min low.
   bar_low=1000;
   Alert(bar_number[0]);
   for (counter2=bar_number[0]; counter2 >= 0; counter2--)
      {
      b_h=iHigh(szimbolum,trade_tf,counter2);
      Print(bar_szam[0]); // I get problem here, counter2 is not equal with bar_number[0] as in for operator needed.
      Print(counter2);
      b_l=iLow(szimbolum,trade_tf,counter2);
  //    Print(b_l);
      if (b_h>bar_high) bar_high=b_h;  // here I try the find the max bar high & low
      if (b_l<bar_low) bar_low=b_l;
      if (counter2!=bar_number[counter1]) {    // if I reach the bar of the next opened trade, the code try to write out the datas 
         continue;
         }
         else {
         Print(counter2+"  "+bar_szam[counter1]);
         if (long_short[counter1]==0) {
            adatok=TimeToString(trade_open_time[counter1],TIME_DATE|TIME_MINUTES)+"   max pip:"+DoubleToStr((bar_high-open_price[counter1]),5);
            bar_high=0;
            }
         if (long_short[counter1]==1) {
            adatok=TimeToString(trade_open_time[counter1],TIME_DATE|TIME_MINUTES)+"   min pip:"+DoubleToStr((open_price[counter1]-bar_low),5);
            bar_low=1000;
            }
         FileWriteString(filehandle,adatok+"\r\n");
         Print("counter1:  ",IntegerToString(counter1,0));
         counter1++;
         }
       
 //     if (counter1==array_counter1) {break;}
         
   }
   FileClose(filehandle);

Maybe in the code are more failure, I don't know coz the script is stoping work properly after for operator.

Thanks in advance for help

Cheers
