Example 2: This is what the source code looks like after dynamic encryption (file attached)
This problem is solved elementary - by deleting all graphical objects at the end of the OnTick function. For better security, the deletion can be performed before all returns.
Dmitry, thank you for your comment!
Are you ready to remove this protection with the elementary way you suggest from the compiled .ex4 file ?
Just this topic talks about additional protections before compilation in order to apply them to ready-to-use files in compiled form

It's just that this thread talks about additional protections before compilation in order to apply them to ready to use files in compiled form
Talking about your obfuscated code. If so (if the file is ex4), it doesn't matter if the source is obfuscated or not.

Dimitri, our practical experience shows that there is a difference

But we do not intend to change anyone's mind
and yet, no, the machine did start doing something.
what I sent.
what came (I had to cut off the ends to fit the message size)
Alexander, finalised, updated the version of the tread, thank you!
I'm attaching the version of the source code you published in encrypted form. Now it compiles without errors.
If you have time and wish you can also send a request for encryption yourself

Have you compared speed before and after?
Dimitri, you asked a good and really important question!
The more complex the encryption and the more additional security algorithms are integrated, the slower the speed.
At the moment, for more or less complex codes, the speed decreases by a factor of 3-5.
As a rule, security is a significant priority over speed, especially since it is not noticeable in the process of trading itself, and optimal settings can most often be provided by the developer, who has the ability to test at high speed the original code without encryption.
