Quoting hanover

Disliked

Anyway, I apologize; no offense intended.

Ignored

//---
hey hanover ....... almost none taken.........

anyway, for those that don't know and might be wondering why, it's because of quid quo pro ....... hanover has multiple times over the years asked not to be vouched for..... i respect his request...... another judgement call......

//---

back on topic......

decompiling has done far more harm than good..... it is what limits the spread of useful indicators and profitable ea's...... people like cja , ferrufx, traderseven and many others are easy targets for decompiling..... and they know it goes with the territory....

the truly ambitious, truly successful, the truly creative, the truly profitable traders/coders are driven further and further away every day....... it's my belief we will see less and less of them........ that's our loss......

are you not successful....... do you believe there are no useful indicators or profitable ea's....... well you'd know different if it wasn't decompiling's........h

to trade and code, keep both simple... no call to impress....h

I would love to learn about decompilation of ex4.
Not that I am in any way interested in decompiling someone's code, but rather my own:
that is, I would like to understand how and where (addresses) functions like OrderSend and such are called, so that I can call them directly from my
dll instead of routing through a script or ea like I have to do right now.
Reverse the encryption so to speak, i.e. to see the machine code clear.
I know about some internal mt4 message codes, but there is no examples how to use them.
If someone knows about this stuff and wants to share, it would be appreciated.

You apparently are misunderstanding what a decompiled .ex4 file is.

this is the original .mq4 file

I would love to learn about decompilation of ex4.
Not that I am in any way interested in decompiling someone's code, but rather my own:
that is, I would like to understand how and where (addresses) functions like OrderSend and such are called, so that I can call them directly from my
dll instead of routing through a script or ea like I have to do right now.
Reverse the encryption so to speak, i.e. to see the machine code clear.
I know about some internal mt4 message codes, but there is no examples how to use them.
If someone knows about this stuff...

yes, as cyber said, you aren't going to learn what you are after by getting a hold of decompiled code. since ex4 is just p-code (not machine code) there probably isn't any nice and easy way of doing what you want.... or then again, there just might be and someone would have to speak-up and say how. if the mql machine happens to use the windows message system, which i highly doubt, then you could possible just send some windows messages and be done with it. but, again, that's unlikely. maybe there is some memory you could inject values into within mt4, but again that's unlikely and you will probably just end-up breaking shit.

chances are you will just have to do it the way you currently are and just interface with your dll's etc via mql code. it's guaranteed to be easier that way nonetheless.

Congratulations ScalaFX for coming out of the closet!

You apparently are misunderstanding what he decompiled .ex4 file is.

I see. Thanx guys for clarifying that. So, yea if it's just some intermediate code it's no use for me. I will have to try to hook into mt4 and see what I can get out this way.
