Are you talking about "consider" and DC?! ;)

It has nothing to do with DC.
 

I've been playing around with a fairly unsophisticated Expert Advisor I wrote. But I decided to add to my expert not one but several signals to enter the market. But I want only one order for each signal to enter the market.

The matter is as follows. I figured out that we can delimit the orders by Magic. The search for orders would look like this:

//+-------------------------------------------------------------------------------------+
//| Поиск своих ордеров                                                                  |
//+-------------------------------------------------------------------------------------+
int FindOrders(int magic)
{
  int t;                                                 // Количество открытых позиции (buy's + sell's)
  int total = OrdersTotal() - 1;
  
  for(int i=total; i>=0; i--)
  {
    if(!OrderSelect(i,SELECT_BY_POS,MODE_TRADES)) continue;
      if(OrderMagicNumber() == magic && OrderSymbol() == Symbol())
      {
        t++;
      }
  }
  
  return(t);
}

Next... we need to open orders for each signal type with its own Magic. For example, for sales I had it like this before:

//+-------------------------------------------------------------------------------------+
//| Открытие коротких позиций                                                           |
//+-------------------------------------------------------------------------------------+
bool OpenSell()
{
  int ticket = -1;
  string myNote = "Сов шортанул";
  
  ticket = OrderSend(Symbol(),OP_SELL,0.1,Bid,i_slippage,0,0,myNote,magic,0,Red);
    return(true);
  
  return(false);
}

At this point, I decided to use the switch operator, is it reasonable to use this operator in this case?

//+-------------------------------------------------------------------------------------+
//| Открытие коротких позиций                                                           |
//+-------------------------------------------------------------------------------------+
bool OpenSell()
{
  int ticket = -1;
  string myNote = "Сов шортанул";
  
    switch(maState)
  {
    case 4:    ticket = OrderSend(Symbol(),OP_SELL,0.1,Bid,i_slippage,0,0,myNote,i_myMagic6,0,Red); break;
    case 5:    ticket = OrderSend(Symbol(),OP_SELL,0.1,Bid,i_slippage,0,0,myNote,i_myMagic25,0,Red); break;
    case 6:    ticket = OrderSend(Symbol(),OP_SELL,0.1,Bid,i_slippage,0,0,myNote,i_myMagic150,0,Red); break;
    case 7:    ticket = OrderSend(Symbol(),OP_SELL,0.1,Bid,i_slippage,0,0,myNote,i_myMagic250,0,Red); break;
    default:   return(false);
  }
    return(true);
}

And this is what the trading function looked like:

//+-------------------------------------------------------------------------------------+
//| Открытие позиций                                                                    |
//+-------------------------------------------------------------------------------------+
bool Trade(int signal)
{
  if(signal == SIGNAL_BUY && FindOrders() == 0)
    if(!OpenBuy())
    return(false);
  
  if(signal == SIGNAL_SELL && FindOrders() == 0)
    if(!OpenSell())
    return(false);
    
  return(true);
}

Should I implement it through the switch operator here too? I was thinking to pass Magic through formal parameters to FindOrders() function too, but I don't know how...

 
Hello. Can you calculate a possible loss for a cross rate, for example GBPCHF, open a 1 lot order and put a 50 pip stop. As far as I know the pip value depends on the base currency, which is unknown what it will show in the future.
 

The value of 1 pip of GBPCHG (if I'm not mistaken) for 1 lot is $8. Thus, if the price goes against you and a stop-loss is triggered, a loss of about $50*8=-$400 will be recorded.

And losses on asc-bid spread (6-8 pips) must be added...
 
So the cost of the item changes every time
 

Question on MT4. I've been testing and optimising the EA for quite a long time (a few days).

Everything was fine. And then suddenly, when I run the EA, it starts to show entry on every bar and exit immediately, in short, not a strategy, but the hell knows what!

Probably somewhere, something went wrong in the settings. Where and what could it be? Help. plz....

Hello.. Can you please tell me how to make a MA or EMA period with a minus value, when the settings do not allow to do so... ? in MT4
Spam?

No!!
Then why post in a couple of threads with one question?
 

The iLow query returns a value with 4 decimal places, although the graph has 5 decimal places.

Because of this, the development of the first mql4 program is stuck. Can you tell me what may be the problem? Or maybe it should be like this?
