Dredding,

You're already 95% of the way there with your routine. All that's left for you to master is how to test your own code...

Create a new script and call it whatever

Copy your function to it

Modify the start() as follows:

Inserted Code

int start()
{
    int MagicNo = GetMagicNumber();
    Print("Magic Number for ", Symbol(), " is ", MagicNo);
}

You can now open this script in various charts and see what the magic number returned is.

It's a good idea to use scripts to polish your code routines one or two at a time. If you...

The other code on mql.com would pick a new magic number for each pair and each trade so no trades would ever have the same magic number so i could have the EA open more then one trade per pair and the EA could keep track of each trade.

Instead of having a unique Magic Number for each trade, why not simply use the Ticket Number?

Im still trying to get everything done to an EA right now i am trying to make each pair have its own magic number. I know this will only work if there is only 1 order open for that pair but i dont code and this is what i think would work for now. Can someone please tell me if it would work.

MagicNo = (StringGetChar(Symbol(),1)*1    // calculate a unique Magic number based on the pair name
          +StringGetChar(Symbol(),2)*100
          +StringGetChar(Symbol(),3)*10000
          +StringGetChar(Symbol(),4)*1000000
          );

How do you determine which orders were placed by which EA ? imagine I have an EA on GBPUSD H4 and another on GBPUSD H1 and a third on USDJPY H1 . . how do I tell which open orders were placed by which EA ?

Plenty of ways to do this.

If you don't care what the magic number is, but just want to track the trade, then you can use a simple counter like so:

Inserted Code

int GetMagicNumber()
{ 
 
   int Counter = GlobalVariableGet("MagicNumberCounter");
   Counter = Counter + 1;
   GlobalVariableSet("MagicNumberCounter", Counter);
 
   return (Counter);
}

This peice of code will not only keep track of your orders but every thing else.... like labaling graphic object, Globals, screenshots, all logs, etc... The numbers are increased by one each time one is pulled. the global variable that holds the next number is not deleted and is let run.

Lets just say that the pullnumber given your EA was 312, if you use that for lets say labaling graphics objects that you can have a simple code to delete all objects 312.... it will delete all objects starting with 312.

track your orders say 312 again was your...

I think I see what you are doing . . . a question. Imagine your PC's HDD died how would you get your account up and running on a new PC and be able to manage any orders currently open ?

No you didn't really . . my question was really about all the info you have in GlobalVariables . . . that info is stored by the MT4 terminal, if you HDD goes down it's lost . . unless you are keeping it somewhere else ?

I didnot understand what you were asking.

I only have two things in GlobalVariables one that generates the Program ID and the other is when an order is being placed theres a lock on the order book to prevent orders form two programs walking on each other.
