Show Positions in History Libraries: Expert New MetaTrader 4 platform

SysFX 2018.03.18 22:54 #4

I'm trying to implement a strategy (which obviously works fine in MT4) but I've hit a brick wall.

The EA begins a new sequence of trades whenever a new signal is generated, so each traded pair will usually have multiple sequences running.

Every trade has an SL & TP, and the EA needs to track what happened (SL or TP) to the most recent trade in each sequence by checking the order history.

Unfortunately, this does not seem to be possible based on the library notes (below) and various attempts to make the system work:

// In MT4 OrderSelect in SELECT_BY_TICKET mode selects a ticket regardless of MODE_TRADES / MODE_HISTORY,
// since "Ticket number is a unique order ID".
// In MT5, the ticket number is NOT unique,
// so OrderSelect in SELECT_BY_TICKET mode has the following selection priorities for matching tickets:
// MODE_TRADES: existing position> existing order> transaction> canceled order
// MODE_HISTORY: transaction> canceled order> existing position> existing order

From experimentation, I have confirmed that the ticket number always changes after an SL/TP event, and that the only common info is the magic number - not even the order comment is retained.

In testing, placing an initial order with an SL, TP, magic number and trade comment returns ticket #2 and displays all of the expected information.

However, when the SL or TP is hit, ticket #2 vanishes and cannot be retrieved using either SELECT_BY_POS or SELECT_BY_TICKET.

Instead, (assuming no other trading activity) there will now be ticket #3, which has no order comment set.

With no consistency regarding ticket number, and no order comment to reference, there seems no simple way to identify the last order in a given sequence :(

Hopefully @fxsaber can find a solution or suggest a workaround :)

Unfortunately, I did not understand the problem.

SysFX 2018.04.14 01:29 #6

Sorry for the late reply :(

The issue is that 'MODE_HISTORY' trade information is basically unusable because:

1) when a trade closes, the ticket number changes ...you can easily test this by opening a buy / sell trade with a TP and SL - if the trade opens as ticket #2, that trade will become ticket #3 in the history pool after the SL or TP triggers

2) the magic number is lost

3) the ticket comment is lost

So, if the EA code needs to check whether a trade closed with a profit or loss, it's impossible because there's no information available to identify the trade.

I'm hoping that you can tweak things to retain the magic number and make the trade comment behave like MT4 - maybe you can find a way to retain the ticket number too.

#define Ask SymbolInfoDouble(_Symbol, SYMBOL_ASK)

#define PRINT(A) Print(#A + " = " + (string)(A))

void OnInit()
{
  long Ticket;
  
  PRINT((Ticket = OrderSend(_Symbol, OP_BUY, 1, Ask, 0, Bid - 100 * _Point, Bid + 100 * _Point, "Hello World!", 12345)));
  
  if (OrderSelect(Ticket, SELECT_BY_TICKET))
    PRINT(OrderClose(OrderTicket(), 0.3, OrderClosePrice(), 0));
}

void OnDeinit( const int )
{
  const int Total = OrdersHistoryTotal();
  
  for (int i = 1; i < Total; i++)
    if (OrderSelect(i, SELECT_BY_POS, MODE_HISTORY))
    {
      OrderPrint();
      
      PRINT(OrderTicket());
      PRINT(OrderMagicNumber());
      PRINT(OrderComment());
      PRINT(OrderTicketOpen());
    }
}

the broker are free to change the comment. E.g. some replace the comment by [tp] or [sl] if the order has been closed by profit target or stop loss!!
