How to get the total number of positions in this code

New comment
 
  • Most EA downloaded from the code base, I can get the total number of positions by encoding;
  • like this
  • void CalculatePositions(int &count_buys,int &count_sells)
  {
   count_buys=0.0;
   count_sells=0.0;

   for(int i=PositionsTotal()-1;i>=0;i--)
      if(m_position.SelectByIndex(i)) // selects the position by index for further access to its properties
         if(m_position.Symbol()==m_symbol.Name() && m_position.Magic()==m_magic)
           {
            if(m_position.PositionType()==POSITION_TYPE_BUY)
               count_buys++;

            if(m_position.PositionType()==POSITION_TYPE_SELL)
               count_sells++;
           }
   return;
  }
    But I can not do this in any EA;

Wow :O What's the alternative?

If the solution to this problem is discussed, then only in Russian.

This issue is known for years now. You have to pay attention that MT5/mql5 is asynchronous.

Anyway I doubt it's the OP problem as the EA referenced is working on new bar only, and very unlikely to have this issue.

 
Yong Zhang:

What do you mean by "I can not do this" ?

You do not understand the problem.

 
fxsaber:

Yeah for sure.

It's amazing how you are arrogant, always thinking you discovered new things, which are well known for years.

I advice you either to explain your points, for everyone to learn something or stop posting in English section.

It looks like you are not even aware of the changes with OrderSend-function that occurred in the last year.

What changes ?

Похоже, действительно заработала. Только что прилетело обновление до 1550, проверил - при открытии позиции сразу после OrderSend() всё окружение синхронизировано.
