Here is an old article about parallel processing in MT5. https://www.mql5.com/en/articles/197
And you can program in OpenCL which gives a lot of more opportunities.

Since no client of me has switched to MT5 itself i will not port any indicator or ea to it. I have my own build libraries for most of the computing the clients requested and own ui for them. All using OO and build 600+ features, so i'm relaxed. When my broker gives me the opportunity to switch to MT5 i will start migrating the stuff, but now i still wait and let them clean up their API for the big bang. If a client moves just before that it's a different game but i don't expect to change a lot to maintain the core functionality.

I have been reading what all of you have said and this is my 5 cents on the subject. I have been a professional programmer working in the financial and commercial real world for a long time, programming in C, C++, Assembler, Dot net and so on. When I retired I did not want to program one single line of code. Instead I set my gaze upon trading. Now whenever a firm builds a program to satisfy a particular clientele, that firm should really start from the onset to realize that the client is boss. Whenever companies forget who the real important people are for their business, they will have to consider repercussions such as losing a lot of clients. I want to trade and I don't want to pay thousands of dollars to connect to interbank systems in order to trade. MQL4 may be crappy to some, but if it does what your clients want, why take it away from them. Unhappy customers are not good business for such companies. I will never use MT5 because I tried it and it does not have the same touch and feel as MT4 and they force the end user to use quirky mechanisms that are counter productive for day to day trading. Hey! if you want to program what you think is a sophisticated "platform" then by all means do so, but do not come to us and force it down our throat and try to minimize all the years of development in an "older" platform. Those efforts were not quaint but huge and some at quite a cost in time and money! Why remove all those years of efforts just because of one man's greed. Nobody likes to be taken for a fool and this is what Metaquotes thinks we are. Knowing people with a knack for opportunity will pick up on this problem and issues MQ forces on us and build an alternative that will not be costly nor take for ever to build and replace. When that day comes, I'll be switching gladly to such alternate means and tell MQ to work with those who want to get riped off or think themselves superior because they understand OOP (Object Oriented Programming). Do your thing and let us do our thing and please stop disturbing the s***. Trading is hard enough. We did not need this and by the way, just for the superior race out there, there are these other programmers who have been very successful programming for a multitude of clients in MQL4 perhaps when you were still a toddler incapable yet of reading or writing.

Thank you. In the article you gave me they start multiple indicators from an EA for parallel processing on multiple cores. Indeed the MT5 is different then, but I do not have problem with this (multi-core) part.
I have not seen any example in which the MQL5 can perform asynchronous calls (with passing callback function). I did not think it could be coded in MQL5, but I was wondering if the OP could do it when he claimed it.

But when this is correct it would make no sense to have the possibility to send an order asyncron. When you only can react on the result withing a single threaded environment. Ok you separate the order filling from your program, but to react on the result your program must wait within the program thread. There will be no advantage in my eyes. But with the absense of syncronising functions and semaphores you probably right that we don't get a real multithreading environment.

Why MT5 doesn't have the same touch and feel like MT4, for a trader? If you reduce it to trading only, then the ways to place an order or modify them must be different. I don't see it.

When you in th IT business before your retirement you should understand the reasons more to let MT4 dry out. Maintaining multiple systems with support and patches is costly. Why blaming MT for thinking about cutting that costs? Do you blame MS when thy stopped maintaining Windows XP and moved to a Linux system (oh, they also changing versions and doesn't maintain older versions ). It's a total normal process, that a software that reached the end of his lifecycle will be replaced.

Using better methods for build better software architectures (it's ont only to use object because some can), makes a good architect/developer superior. Until now i have not seen any tool here and on other forums, that is build with MT4 that comes even close to things like good architecture and design (when you compare it to "normal" software projects outside of the MT4 universe). 99.9% of them are quick hacked scriptes. To port that bunch lines of code to MT5 is not the problem (mostly the real logic is in a couple lines of code). On the other hand, when you have such a good and sophisticated solution build, then keep in mind that in the outside world the owner pays around 20% maintanance per year. So if you use your system 5 years, you can let someone develop it new because i don't think that you paid maintanace for it. In the real world you can't let a program run forever, why should this be in the MT4 world? I bet most of the guys whining here because they don't have the code or glue behind the indicators or systems, because they downloaded it from some dubious sites. Now they fear that this source will dry out.

{quote} Thanks for your reply (also @braintheboss), it confirms what I've read elsewhere. Agree with you, MT4 has been around for approx 12 years now, and there are thousands of MT4 EAs and indicators currently being run by around 20 million users worldwide, on computers and smartphones. If I have to rewrite, I will ditch MetaTrader, and find a manufacturer who provides forward-compatible trading platform/software. Don't want to find myself in the same position when MT6 comes along. Apparently MQ no longer want to maintain/support two platforms....
Hi hanover
How would a forward-compatible trading platform/software look like?
Are there any other platforms supporting EAs? JForex? Ninja? Metastock?

JForex - Java
Ninjatrader - C#

They will not be able to run mq4 out of the box.

In my opinion there is and will be not such a platform. Maybe MT gives the source code of MT4 to public, then i see a chance. Currently can nobody decompile ex4, so how should be someone able to develop a system that will be able to execute ex4 outside of MT4? And even if someone manages this, how would you use it when your broker only runs MT5 servers?

Face it. When MT4 is not supported anymore and the most brokers have switched to MT5 servers the MT4 train ends forever.

Thanks.
Well it's not about if ex4 can run out of the gate on another platform. Obv not.
But as long as ideas can be programmed, who cares what platform it is on. Might cost some money to code it, but if all those who complain here have oh so good and money making EAs, they'll make the outsourcing of the coding back with the EA (assuming they can't do it themselves).

Just go on anothe plattform. Things change all the time.

Btw, what is cTrader running on? Are EAs possible?

From what I gather this all boils down to the same tired arguments that began when mt5 was first borne unto the world:

1) "I'm a shitty trader who loves shitty platforms, and I don't like change."

2) "I'm a shitty coder who can't deal with this fancy new (but actually decades old) OOP concept, and I don't like change."

3) "I'm a shitty trader who can't even write shitty code, and all of my more-or-less identical shitty indicators and strategies won't magically work and I'm too fucking poor / stupid to deal with this. How will the world cope without all of the millions of same-same MA-Cross indicators which now need to be rewritten in something resembling a real language?!?!"

Life is tough, and some of you are seriously precious. Does it have a buy and a sell button? Yes? Then shut the fuck up.

Unhappy customers are not good business for such companies.
With regard to their trading platforms, MetaQuotes' customers are not traders or programmers, but the br0kers who lease MetaTrader. Hence MQ have no need to court traders, especially as there will always be hordes of new trader wannabes, no matter what platform they decide to offer (as long as it's free).

Will not change to MT5.

Will change my broker eg to Dukas or a better one.

It is the principle of the matter & I do not like being force fed.

If you like MT5 good for you but respect the opinions/facts of MT4 users.

What is the issue exactly ?

1) Retail traders love MT4 because they can develop all those nifty sytems and indicators
2) Retail traders lose money

It seems to me they won't do any worse on a platform that is less "Retail Trader Friendly"
If anything, they will lose less ...
