IgnoredIt would take a little less time than it took me to write this sentence. Try Googling 'decode ex4' -- you'll see many listings for decompilers. A decompiled file is not exactly like the original source -- but enough of the original code and APIs remain that an experienced and motivated programmer can figure it out. There is a lot of decompiled *.ex4 indicators and EAs out there.

There could be a difference between decoding and cracking. If the *.ex4 required a license key that could only be validated by a remote license server, then even if the *.ex4 was decoded, execution would fail because the license key was missing. However, in that case, the thief could simply edit the decoded file, remove the code that performs the remote check for the license key, recompile, and then run it without the check.

Pda phone rom update utility htc hd2. So -- you have to be a bit more clever even when using license keys. I think you have to distinguish between two concerns -- protecting your IP or preventing someone from executing the code without having purchased the software and a license key. How you go about solving each of these would require a different approach. IgnoredWhat are you talking about? There are many decompilers to choose from -- give one a try and see for yourself. Look it -- MT4 is a GUI app that uses the Internet to send price data to your computer. To build an executable file -- whether a *.exe that runs in the Windows environment or *.ex4 that runs in the MT4 environment -- you need a compiler.

The compiler that is used to build *.ex4 files is from Microsoft -- and NOT MetaQuotes. Again -- MT4 uses a stripped-down Microsoft C++ compiler. Just like *.ex4 files, *.exe Windows files can also be decompiled. A compiler is a tool that converts source code (i.e. Human-readable text) to binary numbers that represent machine instructions. A decompiler is the converse tool -- it converts machine instructions back to source code. Some things are lost in the conversion -- but enough remains.

Developers can use encryption to protect portions of their source code. You would never encrypt an entire *.ex4 -- only those portions that include the magic sauce. When the *.ex4 first runs it would unencrypt certain portions of the code and load them into memory to be executed. A decompiler will not work in this case but, again, an experienced and motivated programmer can still do a memory dump to gain access to the unencrypted instructions in memory. No one is going to go to that effort unless they know ahead of time there is some pretty valuable information to be had. IgnoredAs a general rule, if it's possible to compile, it's possible to decompile. Although let's suppose it is difficult, there is still someone somewhere that can do it.

Even encryption algorithms are sometimes cracked and their vulnerabilities exposed so why would I assume a file encrypted by MetaQuotes is unbreakable? I would assume it is breakable by its creators MetaQuotes because it's not like they're exactly privacy advocates that are making it a point to take great measure to ensure it's not breakable.

In any case, my suggestion is never to post anything helpful because 99.99% of the people here are ungrateful and begging for a handout. I personally regret any contribution I've ever made. I have said this several times. One should never ever run a compiled MT4 executable from forums especially the ones that requires DDL to be enabled with reviewing the source code yourself and fully understanding what it does. You are simply inviting a thief into your backyard. If anything thinks, just sharing an ex4 file protects your top secret algorithm, please think long and hard. Your BROKER (not metaquotes) can decompile any exe on the fly and reverse-engineer your algo within hours.
