How to create an .EX4 file?

How do you create and .ex4 file in MT? After compiling the code I get the .mq4 file but there is no .ex4 file? I looked in the Programs.../experts folder and there is only the one .mq4 file for the code I just compiled/saved...

I know there are decompilers to open up the .ex4 file but I'm not worried about that right now.
U are sure, that compiling was successful?
Are you sure there isn't any error at your script?
The subject of this thread has sparked a crazy idea in my mind: How about re-engineering the .ex4 format with the goal of creating a better language along with a compiler for it to make important missing features like for example anonymous functions and closures possible?
How about developing a .ex4 generator which is impossible to easily decompile.

E.G. The .ex4 generator is compiled with a scrambler hash of some sort. So the decompiler would have to guess the code to successfully decompile the code.

Just thinking out loud here. =)
Everything compiles fine, no errors, and functions as needed....just don't see the ex4 file. Hmmm....I'll do a search on the C drive when I get home to specify the ex4 file type. It might be throwing it somewhere else for some reason although I don't know why.

And yes, if MT could compile and save with a user encryption for the code that'd be great......

I'll report later tonight....

What a great idea *laugh...

And by that way you would even force the interpreter to guess the code... so every EA is a kind of RR-coin-toss... nice!

Hi Fish,

mq4 file -------------> compile ------> ex4 file
ex4 file will be saved to the same folder as that mq4 file
if it is an EA, normally it would be in experts folder
indicator goes to experts/indicators
script goes to experts/scripts
to run EA/indicator/script, you only need ex4
to edit EA/indicator/script, you need mq4
to convert ex4 to mq4, you need decompiler

hope this help

Maybe yet another instance of the "write into program folder"-problem. Although it is not allowed for programs to write into "c:/program files/*" windows won't throw an error mesage and instead silently maps the file to elsewhere.

MT4 is designed to run on windows98 where there were no user rights settings and home folders. Unfortunately nobody has told the metaquotes people that since more than 12 years we have newer and better versions of windows now in most places outside of Siberia or wherever they live.

change the permissions of the installation folder of MT4 to give the user full write access or install metatrader somewhere else (my documents or wherever the user has write permissions).

If you're running Vista, you need to re-install MT4 somewhere other than under the Program Files folder, like 7bit says.

Apparently Vista does not allow you to write files (e.g. .ex4 files) to folders under Program Files. No doubt it's very frustrating. That's one reason why I'm stubbornly refusing to downgrade from my Win XP. LOL.

HI. Thanks for the reply. But me laos using XP only. I got some other idea now and let me try with it and see.
I have script attach to the chart but i also have an indicator attach to the chart however the script one which is come only in ex4 cause their text to be on top or overwrite text generated by the indicator (actually the text that is generated by indicator is completely hiding by the text generated by the script). Can anyone suggest how to overcome this as i want my indicator text to be viewed instead my script text. Of course not by removing the script LOL. Thans

Write your mq4 files in the Metaeditor and click "Compile" - the result is an ex4 file. Assuming your syntax is correct.
