My question here for people from MetaQuotes (not for moderator).

Does .ex4 that was compiled using build 600 can be decompiled ?

If it can not be decompiled anymore, what measure does MQ uses/takes to make it not decompile-able ?

ps : my english suck

I dont think MQ has ever described the new protection except to say "New EX4/EX5 files are provided with a serious and completely revised protection."

They did describe the protection for MT4 market application, "they do not contain bytecode but only a pure native code signed by our private key."

I think that means public/private key encryption is only applied to MT4 market applications while all other ex4 files have some other kind of new protection.

I did read somewhere that C++ can compile directly to native code (machine code) perhaps MQ has taken advantage of that, I have no clue how that works across a world of different CPU's though, i had always thought machine code is CPU specific. Maybe there is a standard of some kind that PC CPU's adhere to ...

If the new ex4 is machine code that would be very good protection in itself.

So you copied your Indicator .ex4 files to C:\Users\Forex\AppData\Roaming\MetaQuotes\Terminal\9ACB2E2CE0389240C909714389C79575\MQL4\Indicators\ and you restarted MT4, then when the Terminal started your Indicators were not in the Navigator under Custom Indicators ? can you confirm this please ?
 
Yes correct. They are showing in the file in C drive but don't show in navigator.
 
handy148: Yes correct. They are showing in the file in C drive but don't show in navigator.

Have you tried creating a new indicator through the editor?

Does that one show in the Navigator for the Editor?

Does it show in the Navigator of the Terminal?

 

I have just found there are errors showing under experts basically saying cannot open certain files as per example below

2014.02.05 21:15:08.644 Cannot open file 'C:\Users\Forex\AppData\Roaming\MetaQuotes\Terminal\9ACB2E2CE0389240C909714389C79575\MQL4\indicators\SimpleEMAv1.ex4' [2]

This explains why templates not showing correctly but doesn't explain why indi's are not there.

OK, can you show screen shots of the following:

  • the contents of the C:\Users\Forex\AppData\Roaming\MetaQuotes\Terminal\9ACB2E2CE0389240C909714389C79575\MQL4\indicators\ folder
  • the Navigator with the Custom Indicators branch expanded
For example:

and

 

One click trading doesn't appear to be working on build 602 - process stalls & the x button disappears from the open trade line.
