Preparing for the new build 600 MT4 platform

Hi all,

I nearly got caught out with the new build 600 platform that is being forced on to us, it comes with a lot of changes and you may find you need to set things up differently. Below is the information I have collated so far to help people overcome initial difficulties:

This video is an excellent intro to the changes:
MT4 New Build 600 - YouTube

This page gives detailed information on the changes:
MetaTrader 4 Build 574 with Updated MQL4 Language and Market of Applications Released - MQL4 forum

Below is the information from Alpari who in my opinion have been the most prepared of the brokers.

Dear trader,

As a result of the recent MetaTrader 4 (MT4) Build 600 upgrade implemented by MetaQuotes, the folders within the MT4 folder have moved. In addition, the MQL4 language has changed, and this may have interfered with your installed Expert Advisors (EAs) and indicators.

As a result of this upgrade, you should firstly save your EAs and indicators in the new folder location, which is: MT4 > MQL4 > Experts/Indicators.

Secondly, you will need to align your EAs and indicators with the new language to ensure they are fully functional on the updated MT4 platform. To do this, there are two options:

Option 1: Contact your EA provider if you do not have the source code available and request an updated version of the EA.

Option 2: If you have written your own EAs or you do have the source code available, please follow these steps:

Navigate to Tools > MetaQuotes Language Editor – a new window will appear
Navigate to View > Navigator – the Navigator box will appear in this window (if not shown already)
Double-click on the EA/indicator you would like to use and update – the relevant EA script will appear in the main window
Alternatively navigate to File > Open to locate the relevant EA/indicator source code saved on your computer
Click on Compile in the toolbar on top of the main window (or navigate to File > Compile) – a message will appear in the Toolbox window at the bottom
Once this has completed and there are no error messages displayed you will need to close and reopen MT4 – your EAs and indicators should now be ready to use

We’re always here to help, so if you have any questions please contact Client Services at <[email protected]> or call +44 20 7426 2900 (07:00-22:00 UK time, Monday to Friday).

Kind regards,
Alpari UK

It makes sense that Alpari was the best prepared for the new change. They are the default feed providers for the demo version that is downloaded from the MT4 website.

My broker is still testing Build 600+ and has yet to make the change. I’m just lucky my indicators were simple and easily transferred over.

i have follwing code which was working perfectly i old MT4

for (pos36 = OrdersTotal() - 1; pos36 >= 0; pos36–) {
OrderSelect(pos36, SELECT_BY_POS);
if (OrderSymbol() == Symbol() && OrderMagicNumber() == MagicNumber) {
Li40 = TRUE;
Ld_76 += OrderProfit();
if (OrderType() == OP_BUY || OrderType() == OP_BUYSTOP) count44++;
if ((OrderType() == OP_BUY || OrderType() == OP_BUYSTOP) && OrderOpenPrice() > orderopenpricex52) {
orderopenpricex52 = OrderOpenPrice();
ticket48 = OrderTicket();
}

now in Build 600 it generate following error

[B]Return value of ‘OrderSelect’ should be checked
[/B]
it not effect execution and compiling
how i can overcome this issue

So, with this upgrade, it means that our EA will be not work anymore…
If yes, it’s terrible upgrade.

After this sudden update I had to clear my MT… deleted so many robots. But now I stick to my most loved standard MT tools + some free stuff I got from the web. So, it is not that bad after all! Luckily most systems work as before after I reinstalled them.
