Big changes for MT4 2013/2014...

After reading Xaphod post about the planned changes to MT4 I thought to open a thread for it.


Quoting Xaphod
{quote} You are welcome! Build 509 is the latest build and it will probably be for many months more. Metaquotes decided to upgrade MT4 to use a modified version of mql5 which is used in MT5. It seems they underestimated the time it would take to develop the new version by at least an order of magnitude. They have been releasing what they call 'beta' versions on their russian forum. However the releases are more like alpha versions so it is likely to be many months more before they have anything that is production ready. The next version is supposed to run old executable files, however they have made some changes to the mql4 language that will require a lot of the current source code to be modified if it is to be compiled with the new version. Why they don't just include a compiler for mql4 in addition to the new mql5 compiler is beyond comprehension.



Some helpful links:

Ah, these intelligent soviet guys again. They should have stopped mt4 development, stopped selling it, and revoked all granted license so far long time ago. In order to make a smoooth transition to mt5 (what mt4 should have been 10 years ago). Again outdated, however, less so. Instead they started to fumble around with some inbetween bs.

After Upgrade:

1.
it seems my customary include files did not end up in the correct folder: error can not be imported
seems one has to be moved them manually to:

MetaTrader/experts/include > MetaTrader/MQL4/Include

2.
881 errors when trying to compile a simple script: mainly because of the include stuff I have:

- most of my variables used points (.) in there names
- too complex, simplify the macro

but did not find it very helpful - probably most infos are in the Russian forum.

Hello Ati, I am just curious why you need to compile the recent code with the new compiler. I can imagine only two reasons - the new encryption feature and/or the build-in market. Metaquotes promised ex4 backward compatibility, so you may still use any previous editor/compiler to create scripts with the specification you already have been using.
If you decide to use the newer compiler you cannot simply take the recent script and compile. You have to port it, because the language specification changed a lot. The 881 errors are not compiler bugs, but rather number of the language specification violations.

hi Halley,

no reason as I do not need the encryption or built in market. But after being away for a couple of month I planned to start again some coding and the question is what to do: Do I still code for MT4 build 509 or include already consideration for the planned upcoming changes? In fact it seems other much more advanced coders face the same dilemma.

Anyway I made a decision: Going Platform independent! Going pyhon!

Cheers

Ati

What's New in MQL4
* MQL4 programming language has been completely revised reaching the level of MQL5 - now you can develop trading robots in MQL4/5 using the unified MetaEditor development environment, single style, libraries and debugging tools.

* now you can develop trading robots in MQL4/5 using the unified MetaEditor
* To achieve this, we have developed a unified compiler
* MetaEditor will also become a unified application both for MetaTrader 4 and MetaTrader 5 platforms
* MQL5 Standard Library is to be ported to MQL4

Old MQL4 programs can be recompiled with the new compiler in order to easily correct all such errors while following the compiler's messages.

.... is that good or bad news

..read all at the http://forum.mql4.com/59477


Anyway, probably it will be a mixed blessing ... if they can get it to work and brokers accept it

You can put an expensive silk dress on a whore but it doesn't change anything; she's still a whore.
You are in a maze of twisty little passages, all alike.
