I've been trying to purchase a utility program with no success. I can't even get a reasonable response, or email with an explanation as to why I can't make a purchase. Who is the seller here? m I dealing with MQL or the owner of the program? If I have a valid credit card and bank account why can't I do business with the owner and not the robot of MQL. My ticket was closed with no action taken or action taken to resolve an issue unknown to me. As you may have guessed, I'm very frustrated dealing with a site that has no humans on duty during my working hours.

If your program compiles without error but doesn't do what it should use the debugger:

Javier Santiago Gaston De Iriarte Cabrera: no errors, but no trades are done while testing ... why?

Please can some one help me I created an EA but it's not uploading on the chart and not opening trade during testing. I compiled it and no error on it.

If you need help with your code, then you will need to show your code.

Remember to also check your "Experts" log and "Journal" log for any related messages.

Also, please don't hijack other users threads for your unrelated issue.

Faster is to use _Symbol because it is a definition.

Symbol() is a function, so it has to be executed to retrieve the symbol name every time it is called. 

Your code is returning error because your Func() definition expects a CONST string. So it only accepts Static parameters. And you cannot pass a function return to it.

Either modify it removing CONST so you can pass Symbol() to it as a parameter. Or use _Symbol which is faster and ALSO IS a Static Variable ;)

Hi, I have a problem when try to check order at market. I'd like put two parameters into the function as magic and symbol but symbol optional.

If I write "findPos("right magic") doesn't work because it wants the second parameter _Symbol compulsorily...

bool findPos(int_mNumber, string _symbol = NULL)
  {
   for(int i = PositionsTotal() - 1; i >= 0; i--)
   {
      if(position.SelectByIndex(i))
            if(position.Symbol() == _symbol && position.Magic() == _mNumber)
               return true;
   }
   
return false;
  }

I'm currently looking for an ECN broker that has good spreads and proper regulation from either ASIC or FCA. Any recommendations?
