Security for Ea

Any one help me
Plz how can i make the EA Secure and can not be opened for editing and only work in system with password
thanks

Only distribute the compiled .ex4 file. If you want a password, perform a string comparison between a constant value and a string parameter, do nothing if it doesn't match.

Hello I am interested to in this question how i can make the code secure against other.

about the .ex4 files I don`t now so much and also I don´t now very much about this question but i have read here and otherwere that the .ex4 files can be hacked and so the code can be steal !!!

That ist the first question about to make the code only secure against other.

But what if you want to sell one EA and you want just that the one User can use it which you sold him. With a password only I think that is not enough a password can be pass on. the one you sold him can give the passwords to another and than two people use it with the same password, like also the people do with copys of Windows microsoft version !!!

I'am very interested in a solution for that two problems!

How about this,

I can decompe ex4 to mq4 - Forex Trading | MetaTrader Indicators and Expert Advisors

Still secure ?

Yes, it's possible to decompile an ex4.

You could write your code in a dll and reference it, but it's also possible to decompile your dll.

You could use a code obfuscater on the dll, but it's still possible to decompile and "unwind" the code.

The only way to 100% guarantee that your code is never seen is to never release it.

I'll add on to Tesla's comment and say that www.rentacoder.com and other "e-lance" auction sites frequently have EX4 decompiler projects bid for.

People are spending between $100 and $300 to have the decompiler programs built.

Mind you, they are not perfect decompilations of the original MQL code.

The best way is to have your EA rely on and reference a secure site that you control. this way you can distribute the code but when someone wants to use it they have to get to your site for the crutial information.

Hi,

a solution I use, it's to lock ex4 for one account number and an expiration date.

But decompilation is still possible ...

Bye.

instead of worrying about how to make it secure, why not spend the time and effort making an EA that makes profit from trading rather than sales?

I am happy to hear that the password can be cracked as I have a EA that has a time lock and it would have been good to open it and remove it

And you feel that it is ethical to do this? Hmmmm

I my self don´t now so much about how decompiler code and so, but one friend which ist student in prgramming had told me that all people that sell programms just supply machine code something like

010010001010

so i have heard from him to, that this code can also be decompilde but not so easy like a programm with a little bit of code.

Now when I thing a EA is not really much code.

Now I think a way how I can sell a EA without release the code.

Yes I do but I will not go ino details why

Have you done it? Or you still looking for it? Let me know. I have implemented a solution. I assure you will like it.
