In version 509 and above has always worked well.
Microsoft and Apple don't care if my apps from 5_years ago still works, Why should Meta-Quotes?
I have programs like corel_photoshop which came with my old computer_xp. Xp compatibility mode still doesn't let me install these programs. Thats just one example. Don't even get me started with Apple. Software companies come up with new_version of everything every year. Most of these websites do-not even maintain drivers for devices I purchased 3 years ago. When playstation goes from 2->3 || 3->4. All my favorite games from ps1,2,3 become useless. Where is the backward compatibility there? I'm pretty sure I've seen this clause from billion dollar software companies "that operating system is no longer supported". Good Luck.
If people think that all scripts || ea || indicators ever stock_piled online should always be usable within meta-trader then they should perhaps ask what happened to mt1 || mt2 || mt3.
Yeah, and one last reminder.
*** The backwards compatibility was suppose to be mostly for .ex4 files.
Most of the thousands of codes from other forums, mql4_repository, code_base should work.
The ones which doesn't because of special_characters and new_reserve_word conflicts can be easily fixed.
I'm saving a copy of the old_built so that I could recompile those old_syntax should I need to.
The above stuff ^ was known to be the case with the very first announcement.
..........
..........
For the stuff which doesn't work like .DLL support and OHLC_Structure format.
Sure I would love-it if everything worked and I didn't have to lift a finger + new features.
For the .Dll issue:
For the ohlc_structure issue:
..........
..........
I respect that everyone isn't going to agree with these results. But I think MQ has done a fine job thus far.
Lets move onto solving problems .... and let time be the judge :)
regardless if on different user accounts [...]
I know how it's working, and I'd be amazed if the limit were not per user-session on something like a VPS (or a desktop machine), rather than being truly global.
As an added bonus, I now have a security measure which completely prevents MT4 from starting up if I want to make absolutely sure that automated trading has been disabled. <g>
Of course on a VPS it´s a different story since each VPS = a virtual machine on a host and each VPS can launch 32 terminals, this does not apply for the whole server of course in this case. Anyhow, why this limit at all? It just stops many people with big machines from doing serious parallel optimization :( Please MQ, remove that or make MT4 support multi CPU cores! The limit was not there in build 509 and below.
I think the limit will apply per user-session on a VPS, not per VPS. In other words, on a VPS you can typically have 2 connections plus the console session, for a total limit of 3 x 32 = 96 MT4 instances per VPS.
That removes any purpose I can think of for this limit - which, anyway, isn't hard to circumvent. The way it turns out to work is less reliable and more prone to manipulation than some of the other routes which we speculated about.
forexgeeker:
Some interesting discovery I´ve just made: you can only launch 32 MT4 instances of this new build system wide!
This limitation is a problem for me also. 50 instances can be a better limit.
And i wish to have a compact MT4 terminal, to run EA's on multiple accounts of a broker. (One terminal runs many ea's on different accounts?)
