Guys

Thanks

Hi,

Just distribute the EX4 file located in the same folder as the MQ4 source file.

Extended locking features:

To lock it so nobody else can copy the program except the buyer, you can get a programmer to have it so you enter in the buyers trading account number, so only that trading account number will unlock the program when it is compiled. Also, you can put a licensing time so the program will work and then lock up (demo testing). If you want to know who can program this, contact me at ddiebold@sbcglobal.net

If we are talking about ex4 file so you may insert in original mql4 code any account number, for example (in the beginning of the code just below the settings):

Code:

int Account = 111111;

And below

Code:

int start

may be the following:

Code:

if (Account != AccountNumber()){
      Comment("Trade on account :"+AccountNumber()+" FORBIDDEN!");
      return(0);
   }else {Comment("");}

As to trial version so you may do the following (below int start):

Code:

if (CurTime()>1113609600) { //16.04.2005
      Alert("My EA was expired! Please re-new your licence");
      return;
   }

      return;
   }

What is this number: 1113609600?
It is the time in seconds since 00:00 1st of January 1970. It is hard to count the seconds. And if you do not want to count it you may do the following:

1. Create MT3 EA:

Code:

/*[[
Name := babarmughal
Author := Copyright © 2005, MetaQuotes Software Corp.
Link := http://www.metaquotes.net/
Lots := 1.00
Stop Loss := 0
Take Profit := 0
Trailing Stop := 0
]]*/
Var: ExpirationDate(0);
comment(StrToTime("2006.08.16 00:00"));

2. Compile it in MT3.
3. Attach EA to the chart (MT3) and you will see on the chart the number of seconds since 00:00 1st of Janusry 1970 till 2006.08.16 00:00.
