Thread: Security for Ea

Any 1 help me
Plz how Do I Create the EA Safe and Can't Be opened for editing and only work in system with password
thanks

Hello I'm interested to in this question how I could make the code secure against other.

Concerning the .ex4 documents I don`t now so much and I don´t now very much about this question but I have read and otherwere that the .ex4 files could be hacked and so the code could be steal!!!

This ist the first question about to make the code just secure against other.

However, what if you want to sell 1 EA and you need just that the 1 user can utilize it which you sold him. Having a password only I believe that is not enough a password could be pass on. The one you sold him may give the passwords to the next and than two individuals utilize it with the same password, such as the people do with copys of Windows microsoft variant!!!

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

How about this,

Still secure?

Yes, it is possible to decompile an ex4.

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

You can use a code obfuser on the dll, however it is still possible to decompile and unwind the code.

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

I will add on to Tesla's comment and say that http://www.rentacoder.com and other e-lance auction sites often have EX4 decompiler projects bid for.

Individuals are spending between $100 and $300 to possess the decompiler progr assembled.

Mind you, they aren't perfect decompilations of the original MQL code.

The best method is to have your EA rely on and reference a secure site which you control. This way you are able to distribute the code when someone wishes to use it that they have to access to your site for the crutial info.

Hello,

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

However, decompilation is still potential...

Bye.

Instead of worrying about how to make it secure, why don't you spend the time and effort making an EA that produces profit from trading instead of sales?

I am pleased to hear that the password could be cracked as I have a EA which has a time lock and it'd have been great to open it and eliminate it

And you feel it is ethical to do this? Hmmmm
