How to fix problems with MT4 in the terminal - MQL4 and MetaTrader 4

St0nE:

The EA compiles, everything is OK... When I run it in the Strategy Tester, it doesn't trade, it keeps crashing in the logs:

2013.11.25 10:42:15.329 2008.01.03 11:59 array out of range in 'Procedure.mq4' (331,25)

Going to source, it swears at this line:

In 509th everything works...

Should I do this in my own place or is there something in the terminal?

You are out of range of the array. Look for where the index becomes larger than the size of the array itself. In 509 it worked - I turned a blind eye. Everything is much stricter now.

Can you attach a screenshot, and specify the build and OS version

Operating system - Windows 7 x64

MT4 build 547

As an example I have signed parameters of advisor, which is a part of MT4.

input double TakeProfit    =50;  // Тейк Профит
input double Lots          =0.1; // Объём
input double TrailingStop  =30;  // Трейлинг стоп
input double MACDOpenLevel =3;   // Уровень открытия
input double MACDCloseLevel=2;   // Уроветь закрытия
input int    MATrendPeriod =26;  // Период тренда

When we add EA to a chart (variables are replaced by comments from the code, which is very convenient!):

When we go to Expert Advisor settings in the Strategy Tester (variables have original names from the code):

It would be good to make this an option in the MT settings. To replace parameter names with comments or not.

Renat:
Released 548 build, please update.

By the way, about the update.

why is the terminal behaving so strangely?

The terminal starts, I see the new version is being downloaded, and once downloaded, the terminal does not offer to reboot or notify me about the new build.

maybe a window about the new version would be helpful?

There seems to be a message in the log: LiveUpdate finished. This means you can now restart the terminal.

For many updates, the same problem persists. Terminal run /portable, Win7 32. Terminal folder is local D:\NewMT4\, permissions assigned, owner is me as administrator, I don't run terminal as administrator. After starting the terminal, I press F4 - journal entry: 2013.11.26 14:30:33.847 MetaEditor not found. I press F4 again after 5 - 10 seconds and the editor starts, and everything is fine.

Is UAC enabled?

Does it always happen or only the first time after the update?

I mean the dialog box with that explicit sentence. What's that got to do with the magazine?

Maybe we can make it like in MT5, but I can't guarantee it.

Fixed in new build, wait for update
