If they are really acting like this, they will face soon law pursuit ...
Well the platform tells you it's downloading an update and then puts it in a folder named Metaquotes/WebInstall. It's not really that sneaky! It's just an unnecessarily painful user experience.

Yes but it seems that they are using some unacceptable ways to get around our computer security (ref. Kiads post #417).

If the .MQ4 files are in the same folder with the .EX4 files then every time the platform is started or any other .MQ4 document is edited, all the .EX4 files with accompanying .MQ4 files become recompiled.
Strange. I've never seen that behaviour.

{quote} We weren't on the same page ! I was saying that the mq4 files aren't needed in the folder in order for the indicators/EAs to work. This is a general thing even in previous builds. And of course you are 100% right about the mq4 recompiled in the 600+ builds and then being an issue if old code doesn't meet the new requirement.
If I give a custom indicator .ex4 file to a trader for the new Build 600 series, and they install it to the MQL > Indicators folder and then use that indicator - can they ever see the source code? (I am not a programmer so excuse me if this is another one of my dumb questions)

Is this new Build 600 Series like having custom indicators "code protection" inherently built into the new platform upgrade?


- If that is the case, then it seems this Build 600 Series upgrade has a lot to do with Vendor custom indicator code protection....hmmmm?

The protection they seem to provide now with build 600+ is only for files compiled under these new builds. Old ex4 files are still with the old protection (ie. without protection !).

{quote} The following workaround is arguably clumsy, but you might want to try something similar as a last resort. I've used it in prior builds, and I've found it easier than removing and re-attaching the EA to the chart. extern bool compile_lock = true; int init() { if (compile_lock) return(0); //.... rest of init() code } int start() { if (compile_lock) return(0); //.... rest of start() code } Then, after compile and when I want the EA to start running, I press F7 to modify the EA parameters, and set compile_lock to false, effectively releasing...
Thanks for the tip, but I figured out the problem - in the old Metaeditor you had to press F5 to compile. In the new one this still works but it compiles and launches the EA. If you just want to compile without launching you have to use F7.

OK - another follow up dumb question. How would I open an .ex4 custom indicator file in Build 600+ (to see the code in the editor)?

You can open only MQ4 files in the editor. Compiled (aka executable) EX4 files are unreadable by programmers.

The process works as follows:

1. Programmers write source code (for an indicator, EA or script) in the MQL4 language. This file is saved with a MQ4 extension (e.g. my_indicator.mq4).

2. The programmer clicks the compile button. If there are no syntax errors in the code, a new EX4 file is created (or an existing one of the same name is overwritten), e.g. my_indicator.ex4
In other words, compiling means that the computer creates an executable file, from the code in the source file.
If the compiler reports syntax errors, the programmer must fix them, and re-compile, repeating this process until there are no errors.

3. When the trader attaches the indicator, EA or script to a chart, MT4 runs the associated EX4 file. (Only the EX4 file needs to be present at this point).

Right - that all makes sense to me and that is how I thought this all worked in "Build 600 & change" LOL!

So if I give someone an .ex4 file for a custom indicator I have made, and they load it to the updated MT4 Build 600+ they will never be able to see the source code (or ever have any way of modifying that custom indicator).....right?

That is what is supposed to happen but in reality anyone that really wants to see the source code will find a way. I will just leave it at that.

I exited and restarted Axi Trader's MT4 today, and presto, build 600 automatically appeared, without any prompting. Just for fun, I compiled one of my EAs (which has been running happily on build 509 for about 5 months now) and got 102 fatal errors and 132 warning errors. Bravo MetaQuotes!
Hate such stuff, as if other games from these brokers and mt4 were not enough

Similar metaquotes orchestra here , with one of my mt4 a few days back (thank god i have backed up ea copies and folders)


I have been off MT4 for a couple of weeks but as far as i can check , my other mt4 builds (from other (multiple) brokers) have not been force updated or something. Has any one got force/clandestine updates to 600 build with brokers like fxpro/oanda/collectivefx/hotforex/pepperstone?



May god bless traders using mt4, including me ......feels like a good prayer esp seeing some developments lately.

Try this article. It has a simple way to fix this 600 build automatic update mess by MetaQuotes. Also it has a link to download a clean 509 build if that what you wish.

I would sure like to know how it is possible (the mechanics of seeing code from an .ex4 file loaded in 600+) because I have some indicators I would not mind giving out to traders I know - if the code will be protected. I have aspects of some of my custom indicators that I want to keep private if possible.

I know the mentality that about anything can be hacked if the resources are put into play. I would just like to know what level of protection my source code has in reality if I give out an .ex4 file for a Build 600+ user. My background is Engineering, so I like to see the mechanics of the process in my mind - sure would be nice to know. Thanks for all the great input on this subject everyone!

Looks like an interesting page but for now I'll simply compile code that I am having trouble making error free in different saved < 510 platform but I'll keep the link around in case things get even worse (if that's possible). Thanks for it.

It's like we have nothing else to do but have to figure out ways to deal with MT4 now... how sad.

Oanda is still giving the option, so no force. I don't think they will either.

I'm with fxpro and they ain't forced the upgrade on me yet, I'm still running on 509,

I've just sorted it so it won't auto update.. http://4xtrader.net/mt4-build-600-wh...not-update-it/

How to avoid MT4 from automatically updating itself:

Find “webinstall” folder (usually located in C:\ProgramData\Metaquotes) and rename/delete it.
Deny access for the SYSTEM user on the MetaQuotes folder. To do this, right click on the MetaQuotes folder > click Properties > click Security tab > click System > under “group or user names” > check “deny” in lower box > click apply/OK

They'll probably figure out some way to force the update sooner or later.
