why the log file expert/logs/xxx.log not updated automatically?
I am very confused.
The normal complaint is that some lines are missing in the journal. They are all in the file, just skipped in the journal tab when written too fast.
Missing lines in the file is usually because you installed in \program files* on Vista/Win7
Thank you for your reply. I believe it has to do files/folder permission, User Account Control. One way to fix it is to install MT4 not at the default location(C:/Program Files (x86)/), since User Account Control will affects it, instead install MT4 at, e.g. C:/MT4/
I will give a shot today.

Hi,
Sorry to bring this old topic up, but I just faced the same problem: the log files are not updated, just like the original poster explained.
My setup:
Win7x64bit.
I have MetaTrader4 installed on a different (non-system) partition, where every user have write rights.
I have UAC completely disabled.
Still, the logfile is only being updated with the 'contents' of the Experts tab, if I right-click and select Open.
Please advice what to do.
Hi,
As a workaround I came up with the idea of an EA, that executes a small script during every newbar creation. And this script is opening and closing the Logfiles locations, which action is updating the contents of the logfiles.
All source codes that I have used are from this forum. I hope the original posters doesn't mind if don't include a link to their posts...

Hi Tamas Csabina,
Thank you a lot for share your code, i hope you don't mind I use and change a little bit trying to make it work to MT5, It's my first programming attempt so please keep in mind that I don't know almost nothing about it! However my code doesn't update log file at logs/yyyyMMdd.log. My code is right below, someone have any idea how to solve the update log problem?
Thanks in advance

Dear All:
In MetaTrader 4 platform, in the terminal tab "expert", all the messages are also automatically saved in expert/logs/20110825.log (suppose today is 2011-08-25). But recently, I found that is not the case any more: the new messages which show up in termianl tab "expert" are not appended to the 20110825.log file automatically.
If I right mouse click those messages in "expert" tab and select "Open", the Windows Explorer will open. Now, 20110825.log content was updated and contains all the newest messages. In another words, each time new message shows up in "expert" tab, I need to right click the mouse and select "Open" to have the new message appended to the log file. If I don't do that, the log file will not automatically have the new message appended. I am very confused.
By the way, I use Cygwin to go to the directory expert/logs and find and read the log file. The Windows Explorer shows logs/ as empty. -- second mystery.
Thank you very much.
