Thank you. Do Digits need to be changed to 4 or 5 depending on the DC?

You don't have to change it, you just have to take it depending on the currency. MarketInfo

Just leave the Digits, it'll just fit itself.
 
Comrades, considering a very simple system... if the MACD is in the zone for no more than 5 minutes, then I open. For some reason trades don't open.... advise please...

Help! Everyone has a MACD Sample EA I'm trying to add lot calculation to. After my changes it doesn't compile :( Help!
double Lots()
  {
   double Lots;
   Lots=AccountFreeMargin()/10000*5;
   Lots=MathMin(15,MathMax(0.1,Lots));
   if(Lots<0.1) 
     Lots=NormalizeDouble(Lots,2);
   else
     {
     if(Lots<1) Lots=NormalizeDouble(Lots,1);
     else       Lots=NormalizeDouble(Lots,0);
     }
     return(Lots);
  }
 

Hi

EA gives an error, if ((Bid-OrderOpenPrice(),Digits) >= -60) code 130, gives every new tick and really loads server...

if I change it to if ((pBid-NormalizeDouble(OrderOpenPrice(),Digits)) == -60) - doesn't work...

I need exactly >= and how to proceed?

Please help me figure it out.

Thanks in advance!!!

 

How can I programmatically calculate how many currency pairs are involved in a trade?

I tried to search for open orders. I ran the Expert Advisor on 3 currency pairs. I got different results on each one:

on one - 3 (correct), on the second - 2, on the third - 1.

I tried it on 2 currency pairs:

on one - 2 (correct), on the second - 1. If it wasn't for the pattern of decline, I would have thought I had made a mistake

int val()

   int kp=1;

What does it say?
 
Figar0:

Well, what does it say?
12 errors, 12 warnings. I must be entering the lot calculation wrong?

Or maybe just make a list of active instruments with the help of an EA. The approach is kind of complicated. There are simpler ways of doing things, aren't there?

There are no errors in the function itself, probably errors occur when trying to use it, but you don't show us that. Please post something that doesn't compile directly in a file and you won't need to guess.
