If we assumed that the EX4 will not be decompiled then the best way is Client - Server Authentication!
Where the MetaTrader connects to a DLL
the DLL connects to a Server (web server build in PHP)
the Server connects to a database to check the user data (account number - reg number - trial period etc)
This is the perfect method providing the cracker will not crack the EX4 and know the idea of the indicator or the expert advisor!

Comment("Incorrect account : "+AccountNumber()+" Price Display Indicator Deactivated !");
return(0);
}else {Comment(" Price Display Indicator Activated");}
