Thank you!

[Mykola Demko]

Dimka-novitsek:

Thank you!!! Very understandable.

And here... I don't know, I'm embarrassed to just ask, but still, I'm translating the EA. Is that a complete load of bullshit? Just remove the string?

The text_color variable is declared as type color, it's an unsigned type, its value can never be less than zero.

That's your main mistake.

Urain:

Yeah, I didn't write that, I translated it from EmQuele 4, so I'm confused as to what it is. I think maybe color can be compared to a number...

But tell me please, what is it? How this error occurs, from what, where to look in the code??? 2012.10.25 16:29:32 Completely removed print. (EURUSD,M1) cannot load indicator 'Moving Average' [4002]

[Dimka-novitsek]

I spent an hour looking for a place in the EA that mentions MA!!! I can't remember... And. There it is. What to look in it? How can this particular error be picked up?

double CalculateStrengthPairsTF(string a_symbol, ENUM_TIMEFRAMES a_timeframe) {

SymbolSelect(
  a_symbol,       // имя символа
  true      // включить или выключить
   );

    long DIGITS_ = SymbolInfoInteger(a_symbol,SYMBOL_DIGITS);
   //---
    MqlTick last_tick;
   SymbolInfoTick(a_symbol,last_tick);
   double BID_ = last_tick.bid;
   BID_ = NormalizeDouble( BID_, (int)DIGITS_);
  
    MA_handle=iMA(a_symbol,periodd(a_timeframe),Period_,0,method_ma,price_applied);
    //--- заполнение массива MA[] текущими значениями индикатора iMA
   //--- в массив будет записано 100 элементов
   
 //--- если не удалось создать хэндл
   if(MA_handle==INVALID_HANDLE)
     {
      //--- сообщим о неудаче и выведем номер ошибки
     PrintFormat("Не удалось создать хэндл индикатора iMA для пары %s/%s, код ошибки %d",
                 a_symbol,
                  EnumToString(a_timeframe),
                  GetLastError()); ResetLastError();return (0.0);} 
                  
                  
 
   
   CopyBuffer(MA_handle,0,0,100,MA);
   //--- задаём порядок индексации массива MA[] как в MQL4
   ArraySetAsSeries(MA,true);  
   double iMA_ = NormalizeDouble(MA[0], (int)DIGITS_);
           
   ATR_handle=iATR(a_symbol,periodd(a_timeframe),Period_   );
   
    //--- если не удалось создать хэндл
   if( ATR_handle==INVALID_HANDLE)
     {
      //--- сообщим о неудаче и выведем номер ошибки
     PrintFormat("Не удалось создать хэндл индикатора iATR для пары %s/%s, код ошибки %d",
                 a_symbol,
                  EnumToString(a_timeframe),
                  GetLastError()); ResetLastError();return (0.0);}

I'm going to run the robot again to see in what order the error appears... I.e. ATR doesn't seem to make an error, only MA

[Dimka-novitsek]

[Dimka-novitsek]

Can you be more specific about which line it is wrong on? Am I looking in the wrong place?

[Dimka-novitsek]

Added a print.

double CalculateStrengthPairsTF(string a_symbol, ENUM_TIMEFRAMES a_timeframe) {

   Print("a_symbol  " , a_symbol ,"  a_timeframe ", a_timeframe );

Prints did not give anything to understand!!! What to do?????What?????

[Dimka-novitsek]

There are about 1000 places in the EA where the function is called, and honestly I don't understand what could be at least approximately how such an error occurs!!!! What to look for and how to look!!! I'm confused!

[Yedelkin]

Dimka-novitsek: What to watch and how to watch!!! I'm confused!

Have you tried looking at the description of the printed error, Dimon Vladimirovich?
