How to protect your MT4 programs in a very simple way? (Even without being an MT4 programmer)

Surely you have ever wanted to share one of your MT4 programs with a friend or with a potential partner or client. However, you are afraid that your program may be shared with third parties or may even be marketed without your consent. Learn to solve this in a very simple way even without being an MT4 programmer.

Here we show you a very simple way to limit the use of your MT4 program to a single MetaTrader account. This way you can send your Expert Advisor, Indicator or Script to whoever you want with the guarantee that it will not work on any other account except the one you previously authorized.

Simply follow the following steps:

1. Open your MT4 program (Expert Advisor, Indicator or Script) in MetaEditor (press F4 in MetaTrader platform).

2. Copy the following code.

//--- code begin
int AcctNbr = 0;
if(AcctNbr > 0 && AcctNbr != AccountNumber())
   {Print("Account not allowed"); return(-1);}
//--- code end

3. Paste the above code between the brackets of OnInit (initialization function) of your MT4 program. It would look as follows.

4. Compile the MT4 program.

5. Share only the executable file (‘ex4’).
