New comment
 

Hi friends, working on this EA, it is suposed to close all trades if some conditions are met, but it keeps giving this error, any ideas? thanks in advance for the help.. i am not really a programer, just taking bits of code and adding some things but this one i cant make it work...



 if (AccountEquity()<AccountBalance()*Risk)

{
  int total = OrdersTotal();
  for(int i=0;i<total;i++)
  {
    OrderSelect(i, SELECT_BY_POS);
    int type   = OrderType();

    bool result = false;
   
   
   
    switch(type)
    {
      //Close opened long positions
      case OP_BUY       : result = OrderClose( OrderTicket(), OrderLots(), MarketInfo(OrderSymbol(), MODE_BID), 50, Red );
                          break;
      
      //Close opened short positions
      case OP_SELL      : result = OrderClose( OrderTicket(), OrderLots(), MarketInfo(OrderSymbol(), MODE_ASK), 50, Red );
                          break;


    }
    
    if(result == false)
    {
      Alert("Order " , OrderTicket() , " failed to close. Error:" , GetLastError() );
      Sleep(3000);
    }  
  }                   
      

}   

        
 
 if (AccountEquity()>AccountBalance()*Reward)

{
  int total = OrdersTotal();
  for(int i=0;i<total;i++)
  {
    OrderSelect(i, SELECT_BY_POS);
    int type   = OrderType();

    bool result = false;
   
   
   
    switch(type)
    {
      //Close opened long positions
      case OP_BUY       : result = OrderClose( OrderTicket(), OrderLots(), MarketInfo(OrderSymbol(), MODE_BID), 50, Red );
                          break;
      
      //Close opened short positions
      case OP_SELL      : result = OrderClose( OrderTicket(), OrderLots(), MarketInfo(OrderSymbol(), MODE_ASK), 50, Red );
                          break;

   
    }
    
    if(result == false)
    {
      Alert("Order " , OrderTicket() , " failed to close. Error:" , GetLastError() );
      Sleep(3000);
    }  
  }                   
      

}          
        
           
return (0);

  }                            
      
 
Actually it does close a lot of trades that are opened, i forgot to mention that, it is one particular trade it doesnt close, so in the backtest it keeps opened for years and years...
  
  1.   for(int i=0;i<total;i++)

    In the presence of multiple orders (one EA multiple charts, multiple EAs, manual trading), while you are waiting for the current operation (closing, deleting, modifying) to complete, any number of other operations on other orders could have concurrently happened and changed the position indexing and order count:

    1. For non-FIFO (non-US brokers), (or the EA only opens one order per symbol), you can simply count down, in a position loop, and you won't miss orders. Get in the habit of always counting down.

    2. For In First Out (FIFO rules — US brokers), and you (potentially) process multiple orders per symbol, you must find the earliest order (count up), close it, and on a successful operation, reprocess all positions.

  2.     OrderSelect(i, SELECT_BY_POS);

    Magic number only allows an EA to identify its trades from all others. Using OrdersTotal/OrdersHistoryTotal (MT4) or PositionsTotal (MT5), directly and/or no Magic number/symbol filtering on your OrderSelect / Position select loop means your code is incompatible with every EA (including itself on other charts and manual trading.)

Hello friend. thank you very much for your help, i don't really know a lot about coding, the EA does open multiple positions, but isnt this part of the code the one in charge on counting? is it some error there?


{
  int total = OrdersTotal();
  for(int i=0;i<total;i++)
  {
    OrderSelect(i, SELECT_BY_POS);
    int type   = OrderType();
 

  1. What part of “you can simply count down”, “and check OrderSelect”, and “no Magic number/symbol filtering” was unclear?

  2. That code has nothing to do with counting.

  3. MT4: Learn to code it.
    MT5: Begin learning to code it.

    If you don't learn MQL4/5, there is no common language for us to communicate. If we tell you what you need, you can't code it. If we give you the code, you don't know how to integrate it into your code.

    or pay (Freelance) someone to code it. Top of every page is the link Freelance.
