Alexey Navoykov:
Inline is a relic, in my opinion. The compiler inlines everything fine by itself, so there is no need to overload the code. And in MQL this specifier is nothing at all, added only for compatibility (I don't know what for, if one could declare such a macro by oneself).

And who can guarantee that the compiler has inlined 100500 calls of GetTo() function in a loop, if call is preceded by if(something) and this something is false once in five years?

I find it easier to write inline than to look through the disassembler code to check it.

Excuse me, are you disassembling ex4, ex5 codes?

Artyom, as a moderator please help me with this, I wrote earlier :

"For site administrators:

I couldn't find where, I'm writing here

Need to change the details of the seller in the profile.

how to do this ?

I wrote a message a long time ago in the seller's account, no reply.

maybe there is another way ?

Write to this thread (+ passed your request to the administration):

No. Is there any fundamental complexity there?

Not to be confused with decompiling - these are different things.

I asked a specific question. You gave a specific answer.

And "confusing something with something" is your own fabrication. Please don't worry - I know, and I am not confused, and your other questions are redundant here.

And you managed to optimize a lot with your inlines in Release mode? )

p.s. Weren't you the one who was messing around with alignments the other day?

My friends, can you tell me what it is doing, one month everything was working fine, but I dared to load a deposit and now I got an error - karma is black :(

Here is the indicator call from the Expert Advisor

//+------------------------------------------------------------------+
//|значение Regressor Номера буферов: 0 - Up, 1 - Center, 2 - Low    |
//+------------------------------------------------------------------+
double Regressorf(int Bufer,int index)
  {
   double MA[1];
   ResetLastError();
   if(CopyBuffer(handle_Regressor,Bufer,index,1,MA)<0)
     {
      Print("handle_Regressor: Bufer=",Bufer," index=",index);
      PrintFormat("Failed to copy data from the handle_Regressor indicator, error code %d",GetLastError());
      return(0.0);
     }
   Print("handle_Regressor: Bufer=",Bufer," index=",index," arr=",MA[0]);
   return MA[0];
  }

Since July I actively tested everything on a real account under my watchful eyes, there was no error, and now I have it :(

What can it be? At the same time the indicator itself visually works, re-initialization of the EA solved the problem.

Good afternoon!

This may be a silly question, but I can't figure out what I'm doing wrong. I started to learn MQL5 and the first problem arose. I cannot use script for immediate opening of an order (buy/sell, any order at all). I just took the ready code from MQL5 Reference and tried to run it (attach the script to the chart window). It did not work. When compiling, no errors occurred, of course. I cannot attach it to the chart. Maybe everything is obvious, but I am at a loss.

#define  EXPERT_MAGIC 123456   // MagicNumber эксперта
//+------------------------------------------------------------------+
//| Открытие позиции Buy                                             |
//+------------------------------------------------------------------+
void OnStart()
  {
//--- объявление и инициализация запроса и результата
   MqlTradeRequest request={0};
   MqlTradeResult  result={0};
//--- параметры запроса
   request.action   =TRADE_ACTION_DEAL;                     // тип торговой операции
   request.symbol   =Symbol();                              // символ
   request.volume   =0.1;                                   // объем в 0.1 лот
   request.type     =ORDER_TYPE_BUY;                        // тип ордера
   request.price    =SymbolInfoDouble(Symbol(),SYMBOL_ASK); // цена для открытия
   request.deviation=5;                                     // допустимое отклонение от цены
   request.magic    =EXPERT_MAGIC;                          // MagicNumber ордера
//--- отправка запроса
   if(!OrderSend(request,result))
      PrintFormat("OrderSend error %d",GetLastError());     // если отправить запрос не удалось, вывести код ошибки
//--- информация об операции
   PrintFormat("retcode=%u  deal=%I64u  order=%I64u",result.retcode,result.deal,result.order);
  }

Please advise me, what is wrong? Or the code is correct and I'm just a clumsy one?
