Dynamic (Magic Number) - Randomizing

I have created a routine that generates a magic number that is unique to each EA that I run.

int AutoMagic()
{
   string 
      Cur1 = StringSubstr(Symbol(),0,3),
      Cur2 = StringSubstr(Symbol(),3,3),
      magic1 = 0,
      magic2 = 0;
 
   int 
      Period_ID = 0;
 
   if (Cur1 == "EUR") magic1 = 1;
   if (Cur1 == "GBP") magic1 = 2;
   if (Cur1 == "USD") magic1 = 3;
   if (Cur1 == "AUD") magic1 = 4;

   }
   if (!GlobalVariableCheck(AutoMagic)) GlobalVariableSet(AutoMagic,StrToDouble(AutoMagic));                      // MagicNumber does not exist, so write it as a Gvar
   if (EA_Instance_UID > 1 ){
         Print("Note that this is instance number " + EA_Instance_UID + " of this EA on this currency pair!");    // alert the user to the conflict
         Alert("Multiple instance of same EA & same currency pair. Check your risk settings. EA_Instance_UID reassigned!");
   }
   return(StrToInteger(AutoMagic));
}

I wonder.... Magicnumber is of the int datatype, perhaps using a negative value might yield some unusual effect?

Hi all,

I was also thinking of combining several EA's into one account to throw them off. Any thoughts?

hey blue.... actually the only thing that has come to my mind over the years would be exactly the opposite.....

if you split the ea's trades between several accounts, the complete overall pattern is far more difficult to see.... and that is very easy to
accomplish.....

it's in a brokers best interests to know what is going on.... some watch closely...... at least one time in recent history many people using the same two expert advisors at the same time with a particular broker were taken off the common spreads and forced to use a worse...

All,

Thank you very much! RR, this script will be great, will have to test it.

Here is a way to totally hide your EA. I believe it's foolish do do such a thing, but anyway:

1. Have one computer run your real EA on a demo account of your broker.
2. When the real EA wants to open/close an order, send it (using the DLL interface) to another computer running your real account MetaTrader.
3. On the second computer you have a NON-METATRADER script receive the orders from the real EA running on the first computer.
4. This script will use AutoHotKey to press the...
