Hello, i have a question about metatrader 4 and its updates.

So i have read (for years) that they want metatrader 4 users to go to mt5 and due to some mt4 updates some indicator/EA stop working on the updated version of mt4.

I would like to maintain my indicators if that happens, so with the ones that i have the source code there is no problem, but is there any way to preserve the .ex4 indicators in case that happens? Like downgrading mt4? Or not allowing the updates or something like that? I have no idea so i would appreciate any help.

Thanks for your collaboration!

Good question.

If MT4 were to just "suddenly stop" one day altogether, Mladen has been porting a lot of indicators over to MQ5 over the past few years and if there's a certain MT4 code you need, guys like Mrtools, Xard, Banzai, Kvak and Pacois would usually have the sources. In worst case, an indicator could be made again from scratch in MQ5 if that code was not available, lost etc.

Don't despair, MT4 will still be around for a while

MT4 is more lightweight and quick to use so I still like it, MT5 is more of a big whale, kinda slow and complicated but more powerful

now that u mention about it.............. that is true mt5 is a bit heavier what about mt3?? u can download it from here viewtopic.php?t=8474252

So aside from "searching" the source code there is nothing i can do for maintaining those ex4 indicators? Like stop mt4 from updating or something? I mean maybe now it is possible to do something, but once a mt4 update makes a indicator not work you cant so anything.

The only way to to stop MT4 (and also MT5) from updating

In Windows, completely remove all access privileges to the directories where the updates are being stored.

Don't change the actual Ownership of the directories.

The primary directory is:
"%APPDATA%\MetaQuotes\WebInstall"

To block updates, revoke permissions to the download directory:
"%APPDATA%\MetaQuotes\Tester\LiveUpdate"

You'll need to know how to set Permissions and Security Settings for directories on your Windows but that's the guaranteed way of doing it.

And would still continue working (can open buy sell operations?) or would it be like "offline" mode if i do that? Does this create any problem?
Thanks for your answer!
