MT4 build 830

  • First Post: Jun 2, 2015 1:38pm Jun 2, 2015 1:38pm
Well those dipshits at Metaquotes forced another MT4 update today and now I'm getting the following compilation error when compiling my EA:

ObjectsTotal - ambiguous call to overloaded function.

The line in question:
x=ObjectsTotal(OBJ_TREND)+1;

This was compiling before the update and from the MQL docs they haven't changed the ObjectsTotal() function in any way, so clearly this is a bug.

Is it just me or is anyone else having the same issue?

Also can anyone offer any advice on preventing MT4 updates? I've renamed all occurences of "liveupdate.exe" on my system and it still updated my MT4...

It's just a matter of being a little more explicit.

Just force it to use the function you want like this:

Inserted Code
x = ObjectsTotal( (int) OBJ_TREND ) + 1;

It is called User Account Control (UAC)!

You are wrong, UAC has nothing to do with some kind of compiler error.

The problem you see is actual a good thing.

MQL4 is a weak typed language. Personally I wonder why someone wants to use such a crap for money related (or other important) computations but well, it's the usual lack of choices I guess. Anyway, that problems of these kind occur just means that Metaquotes is cleaning up the mess they fabricated in the past. If you write proper code and look for correct typing or type casting where necessary you'll have a lot less problems after upgrades.

Thanks for the help, it works.

@JensG
If I wanted to cast everything I'd code my EA in C++ :-) I've looked for alternatives to MQL4/5 but there aren't any with wide support, can you recommend anything?

I been having issues with my EA and I think it might have something to do with the new build. Is anyone else having problems with your EA since the new build 830 was released?

Why can't they just leave the MT4 alone and stop driving us traders crazy! I think they get a perverted pleasure out of screwing up our EAs.

I don't think they get any pleasure in screwing anything.

The latest updates since build 600 have dramatically improved our possibilities to write better code and OOP.
I have an EA built before build 830 which works perfectly on the latest build and on a live account.

Each time I had a problem whit it, it was because of a bug of mine, not a new build.

Well, the person that started this thread has the username is "MT4Coder", and therefore I assume he is a coder and thus he understands whether or not all these updates are needed or not. As he wrote in his original post of this thread, "Metaquotes forced another MT4 update" upon us with this new build 830. That isn't exactly a ringing endorsement for the multitude of udpates Metaquotes is always forcing upon us. I agree with MT4Coder. I don't understand why they continuously just HAVE to ALWAYS be updating the MT4. The MT4 platform has been around for quite some time now. And, after all this time, it should now be a rare occurence that the MT4 needs to be updated - it should not be a regular occurence of it happening almost every month or two.

At least, that is how I feel about it.

If he was really a coder, he would probably know that software is a living thing and needs to be updated continuously, first because programmers are not perfect and put bugs in it and second because customer needs and desires evolve also continuously.

Without this evolution, we would still be at stone age calling our brokers over the phone to place a trade.

It is irresponsible to force broken software updates onto users, particularly when it is critical software. Ie, users are trading real money with the software and stand to lose real money when the software breaks.

Example, you have an EA running with open trades. For some reason, the server or software is restated. Betatrader proceeds to update. The new version of Betatrader and fails to start your EA(s), fails to run your EA(s) correctly or perhaps even crashes on start. Oops, what about your open trades? Winners or Losers?

Any company with competent software engineers would understand that they should have 'extended support releases' which are versions that have been proven to run correctly and are supported for an extended period. This gives the users time to evaluate and upgrade to the next 'extended support release'

The circus is still going on....

New MetaTrader 4 Platform Build 825: Product Renting in Market and Testing of Indicators
MetaTrader 4 platform update is to be released on Friday, May 22, 2015. The update will feature the following changes:

New MetaTrader 4 Platform Build 830: Hotfix
MetaTrader 4 platform update is to be released on Monday, May 25, 2015. This hotfix update build 830 follows the previous major release. The new version features corrections in the CopyTime function

So a function that is critical to the correct functioning of some EAs and indicators is not working correctly. Perhaps that is why any EAs that use said function have been loosing money since the update? Amateur hour at Metatrader. Awesome. But you can buy magazines, indicators and EAs directly in the program and that is the most important thing.

First, there is the UAC that helps avoiding being forced as you said to update the software. So in fact you are not forced at all you can either choose yes or not when you are prompted about the update.

Second, we talk here about the client software MT Terminal not a server software and why should it be restarted for some reason, A crash of your pc ? then that brings you to first point where you have to allow any software update so what's the problem ?

When we went from build 590 to 600+ instead of updating blindly I installed the new build on a separate folder and kept my EA running on the old build while at the same time testing it on the new build, I did that for several months until I was sure I could move to the new build.

It's not so complicated, so you should stop crying and instead act responsibly if you use a critical EA and thus, by not allowing any update until you have tested it on the new platform. It seems so obvious but still people don't get it...

Thanks for the mental gymnastics exercise.

Yes, computers do crash. This is a known fact. Also, EAs are often run on VPS services where users do not have control of the physical hardware.

Using UAC and playing whack a mole with the updating software is not really an acceptable solution for software that is trading real money.

Yes, it is obvious if you are good at mental gymnastics.

Sorry, it was an exercise for you, so I understand now the pain.

Never said that playing with the update was the solution, just a turn around while waiting for the updated EA but that was too much gymnastic for you eh ?

You make me laugh, I run an EA on a $100 account from my PC at home and you argue that some run on VPS, I hope that they are not the ones that are so critical and if so, that they are not on russian or chinese servers...

And yes, some EAs trade real money, this is a known fact too, stop thinking you are the only one trading it with your so critical EAs

It's also known that when we run short on arguments is better to turn the conversation on the other guy instead of talking the subject.

Stay invisible, someone could come and see that you here. Boo!

delete your webinstall folder... it will prevent auto update..

as an added precaution backup your terminal.exe and metaeditor.exe somewhere..you can revert by overwriting the new files..

825 was a massive failure.. good thing they came back with 830 ...

so far 830 works ait.

@broketrader:
You said "First, there is the UAC that helps avoiding being forced as you said to update the software. "

Well the UAC won't help if you're running an EA on a VPS and the machine reboots, loads MT4 and you're not around to say "no" to the update. A professional trading platform should give the user the decision whether to upgrade or not, so that we can do so at our own convenience.

"If he was really a coder, he would probably know that software is a living thing and needs to be updated continuously"

Actually, I have software I haven't updated for 5 years and still works perfectly, perhaps you shouldn't judge all programmers by your own standards! I also posted in the thread about the 711 build memory leak which, guess what, turned out to be a memory leak which they then fixed. Fact is Metaquotes are releasing unstable builds and not giving users the opportunity to opt-out. If that's your opinion of how things are supposed to be done then you're entitled to your opinion, although most of us with experience in these matters would disagree.
