Block EA only for a specific account

may give you ideas:

The functions of the client terminal and status checking functions are convenient to be applied for program restriction when it is distributed on the commercial basis, for example. Let's examine the solution of the problem below:

.

A group of functions to access to the active account information.

like you do for !IsDemo()

can do for account maybe something like this?

int liveAccountNumber = 202020;

if( AccountNumber() != liveAccountNumber )
{
  Alert("Account Number not recognized");
  return(-1);
}

paulo, ok then - why not use "if (AccountNumber() != liveAccountNumber) return(-1);" in at beginning of start() instead of:

int start()
{
if (!AccountNumber()) return(-1);

...

reason? because start() still gets called each data tick. so what you had in init() may issue the Alert("..."); but you also need the if(...)return(-1); at top of start() too.

Please notice your code: if (!AccountNumber())

why? AccountNumber() is a typed function returning an int value - is not used like a bool so you must have something like this:

int start()
{
if (AccountNumber() != liveAccountNumber) return(-1);

...

//do trading here if AccountNumber() is same as liveAccountNumber

...

return(0);

}//end of start()

can keep init() like it is but above should stop further execution of EA if running on account number different than liveAccountNumber.

If formatted, for example:

void start()
{
  int    i, b=0, bb=0, eb;
  string comm, st;
  string fn=Symbol()+Period()+" "+
         TimeToStr(BeginDate, TIME_DATE)+"-"+
         TimeToStr(EndDate, TIME_DATE)+".csv";

  for (i=Bars; i>0; i--)
  {
    if (Time[i]>=BeginDate && Time[i]<=EndDate)
    {
      if (bb==0) bb=i;       // фиксируем номер первого бара
      st=TimeToStr(Time[i], TIME_DATE)+Separator+
         TimeToStr(Time[i], TIME_MINUTES)+Separator+
         DoubleToStr(Open[i], Digits)+Separator+
         DoubleToStr(High[i], Digits)+Separator+
         DoubleToStr(Low[i], Digits)+Separator+
         DoubleToStr(Close[i], Digits)+Separator+
         DoubleToStr(Volume[i], 0);
      WritingLineInFile(fn, st);
      b++;
      eb=i;        // фиксируем номер последнего бара
    }
  }

  comm="Начало: "+TimeToStr(Time[bb], TIME_DATE|TIME_MINUTES)+"\n";
  comm=comm+"Конец: "+TimeToStr(Time[eb], TIME_DATE|TIME_MINUTES)+"\n";
  comm=comm+"Выгружено баров: "+DoubleToStr(b, 0);

  Comment(comm);
}

Why? unable cope with left justified programming code... need structure else unable/willing to keep file open longer than takes to close it... ;)

If you have source file layed out (formatted) block structure etc, then why not post?

Many able people live on forum, yes?

I will look but cannot make promises - nor can [I believe] others make promises.

Unless of course you contact money wanting person. For that, is link/article on forum to guide you in selection of [hopefully] decent programmer.

An idea: In computer programming, an indent style is a convention governing the indentation of blocks of code to convey the program's structure....

UNformatted:

int init()

if (!IsDemo())

return(-1);
}
else

return(1);
}
