When you scan the orders collection by the "for" loop, you have to check if the selected order is on the current symbol, otherwize you will quickly do some greek salad...

PHP Code:


			
  for (int i=0; i<OrdersTotal(); i++) {

    if (OrderSelect(i, SELECT_BY_POS, MODE_TRADES)) {

      if(OrderSymbol()==Symbol()) TrailingPositions();

    }

hi, how to code multiple entires eg.....

// check for long position (BUY) possibility
if ( Macd3 > Macd2 && Macd2 < Macd1 && Macd2 < -0.0045 )
if ( Macd3 > Macd2 && Macd2 < Macd1 && Macd2 < -0.0030 )
if ( Macd3 > Macd2 && Macd2 < Macd1 && Macd2 < -0.0015 )

This code is taken directly from one of my EAs:

PHP Code:


			
double balanceDeviation()
{

   double equit = AccountEquity();
   double bal = AccountBalance();
   
   double val = ((equit/bal) -1) * 100;
   
   return (val);
}

hey guys hows it going

i have a quick question, is there any why of converting an mq4 file into a .DLL file? i need an mq4 indicator in converted into a .DLL indicator in C+ or C. would it be hard for a programmer to write a converter? if not then ill look into hiring a coder.

Hi guys,
Often, when I try to modify a mq4 file with MetaEditor, I get the message “Access is denied” and I cannot modify the file. How do you guys deal with such a problem? Thanks!

Please disregard post. This setting did what I needed it to do. Thanks for begin there to help us.

I have modified an EA to work with several methods. I have done some research but can not figure out how to add the name of the EA to the comments field when opening an order. Can someone please point me in the right direction.

I am hoping there is a simple string command that I can integrate into any EA I modify so that the orders are better organized when running more than one EA during a test.

Thanks for your time and insight.

Here is one of the non-modified sections I will need to change to input the EA comment.

Code:

   if(ObjectFind(BuyStop_TrendName) == 0)
     {
       SetObject("Active" + BuyStop_TrendName,
                 ObjectGet(BuyStop_TrendName, OBJPROP_TIME1),
                 ObjectGet(BuyStop_TrendName, OBJPROP_PRICE1) + BuyStop_StepActive*Point,
                 ObjectGet(BuyStop_TrendName, OBJPROP_TIME2),
                 ObjectGet(BuyStop_TrendName, OBJPROP_PRICE2) + BuyStop_StepActive*Point,
                 ObjectGet(BuyStop_TrendName, OBJPROP_COLOR));
       SetObject("Prepare" + BuyStop_TrendName,
                 ObjectGet(BuyStop_TrendName, OBJPROP_TIME1),
                 ObjectGet(BuyStop_TrendName, OBJPROP_PRICE1) - BuyStop_StepPrepare*Point,
                 ObjectGet(BuyStop_TrendName, OBJPROP_TIME2),
                 ObjectGet(BuyStop_TrendName, OBJPROP_PRICE2) - BuyStop_StepPrepare*Point,
                 ObjectGet(BuyStop_TrendName, OBJPROP_COLOR));
       vA = NormalizeDouble(ObjectGetValueByShift("Active"+BuyStop_TrendName,0),Digits);
       vM = NormalizeDouble(ObjectGetValueByShift(BuyStop_TrendName,0),Digits);
       vP = NormalizeDouble(ObjectGetValueByShift("Prepare"+BuyStop_TrendName,0),Digits);
       sl = vA - BuyStop_StopLoss*Point;
       tp = vA + BuyStop_TakeProfit*Point;
       if(Ask <= vM && Ask >= vP && OrderFind(MagicBuyStop) == false)
           if(OrderSend(Symbol(), OP_BUYSTOP, BuyStop_Lot, vA, 3, sl, tp,"", MagicBuyStop, 0, Green) < 0)
               Print("Err (", GetLastError(), ") Open BuyStop Price= ", vA, " SL= ", sl," TP= ", tp);

       if(Ask <= vM && Ask >= vP && OrderFind(MagicBuyStop) == true && 
          glbOrderType == OP_BUYSTOP)
         {
           OrderSelect(glbOrderTicket, SELECT_BY_TICKET, MODE_TRADES);
           if(vA != OrderOpenPrice())
               if(OrderModify(glbOrderTicket, vA, sl, tp, 0, Green) == false)
                   Print("Err (", GetLastError(), ") Modify BuyStop Price= ", vA, 
                         " SL= ", sl, " TP= ", tp);
         }

       if(Ask < vP && OrderFind(MagicBuyStop) == true && 
          glbOrderType == OP_BUYSTOP && AutoClose==true)
         {
           OrderDelete(glbOrderTicket);
         }
     }

I am not sure of the logic but can I just input the CommentName in the following location? I have not tested this but it compiles fine.

Code:

if(OrderSend(Symbol(), OP_BUYSTOP, BuyStop_Lot, vA, 3, sl, tp,"CommentName", MagicBuyStop, 0, Green) < 0)
 Print("Err (", GetLastError(), ") Open BuyStop Price= ", vA, " SL= ", sl," TP= ", tp);

Thank you Coderguru for being here for us!

I have a question about Alerts.

I want to change the alert type in this code so it will play a wav file that I choose and not have the popup window buy sell thing. Just play wav file when fractal apears.

How should the code be. I have attached the sFractals alert indicator.

if(PrevSignal <= 0 )
{
if(ExtDownFractalsBuffer[SIGNAL_BAR] > 0)
{
PrevSignal = 1;
Alert("sFractals (", Symbol(), ", ", Period(), ") - BUY!!!");
}
}
if(PrevSignal >= 0)
{
if(ExtUpFractalsBuffer[SIGNAL_BAR] > 0)
{
PrevSignal = -1;
Alert("sFractals (", Symbol(), ", ", Period(), ") - SELL!!!");
}
}

That will work fine. You can also put a string variable in that place.

I think CodersGuru died or something.

He hasn't been around in a while.

Anyway.... add this statement:

PlaySound("alert.wav");

.... where "alert.wav" is the name of the file that you want to play.
