Does Metaquotes purposely disable old EAs/indis ?

hello fellow traders.

in my time trying to find the best EA possible, i've encountered countless EAs that were working perfectly fine, until a new MT4 version is released that disables completely the EA/indi. And of course i didn't have the source code

the usual message is : "Global Initialization failed", sometimes there is no message.

I suspect Metaquotes of doing it on purpose so we come to their "Market" where all the EAs are up to date with latest MT4 of course.
I'm also a programmer so i was able to pinpoint WHY some EAs are disabled.

well in the history of MT4 programming, some things have changed regularly.
For instance, in the past, it was usual to use "Start()" instead of 'OnTick()' now. Why this change ? i don't know ! Why would there be? except for making old programming rules obsolete ?

lots of other changes have occurred during the history of MT4, all without good explanation on WHY they are.

Do you guys have the same opinions about Metaquotes planned obsolescence?

thanks

Jeff

MT5 will replace it. No idea when.

They did this so that they could implement many of the new features of MQL5 in MQL4 such as new event handling default functions and OOP. They did a poor job of making the platform run legacy programs, but overall the new update is worth it because now you can make more complex algos with less hassles.

ok but then why disable old version of MT4 ? i would be fine using 1045 but no you can't do that anymore. This is an indication on where this is going

and the changes i've seen are definitively NOT improvements, but rather specific code made to disable old EAs

MT5 will never replace MT4 IMHO, MT4 is too popular

That's a matter of opinion, I suppose. As someone who has been programming in mql for many years, it's my opinion that the upgrades were much needed, especially OOP implementation. Metaquotes decided that the trade-off to not fully support poorly designed legacy code in favor of keeping MQL current was to the benefit of programmers still developing in MQL4, and I strongly agree. Traders with old legacy programs that don't know how to program will strongly disagree.

Metaquotes has already stopped supporting MT4 with new updates in order to focus all of their development efforts into MT5.

Partially true, Mt5 introduced long time ago but still Mt4 live and Mt4 is traders friendly and Mt5 is good for company/coders/EA sellers so on. Now Mt5 will bring more business for Metaquotes instead of Mt4.

They are not disabling them
But what has been done with build 1090 is far from anything normal. Not that new builds of mt5 are any better regarding "improvements" (some of the bugs in newest builds of mt5 are plain ridiculous). We can scratch the conspiracy (money is money, regardless of the source they are getting it from), more probable cause is "human resources exhaustion" issue (not to use some ugly words ).
