If you cant find the problem, you could set up a Virtual Machine and install linux with wine and have your MT4s on one separate VM.

I normally run five MT4 instances on Windows 10, and this has been stable for several years. However, after recently upgrading to Windows 11, I noticed that sometimes one or two out of the four MT4 instances automatically close within half a day. This interrupts my trading and causes some EAs to reopen positions at unfavorable levels. No matter how much I search, I cannot find anyone who has the same issue or a solution in Windows 11. And MT4 closes without any errors or warnings. I have already set Windows 11 to best performance mode, and turned...

{quote} Hi LF, I'm essentially a pragmatist. Go back to your stabler Windows 10 imo if your main pc function is for mt4 trading. Win11 was designed mainly for gamers I think and game speed enhancements and game data retrieval functionality. In the end it's only an operating system, it is not god-like as M/S developers might like you to believe in that every new version is. Wishing you good fortune with it

And Metatrader 4 works with it, I run as many as he does without any issues. He needs to solve the problem, not dodge around it, which only creates additional issues in the future. {image}

how much is your system Ram memory, and what is your Antivirus, using external or windows defender, are important issues that must be checked by yourself

{quote} Thank you for your replies and assistance. I am sorry for not being able to check the forum for a few days due to being busy with family matters; I apologize for this. My computer’s CPU is an I5-13400 with 32GB of DDR4 RAM and a 1080 display card. I run 5 MT4 instances and most of the time, the CPU temperature stays between 35~40 degrees Celsius, with the CPU fan speed generally at 1150 RPM. The CPU usage around 30%, while RAM usage around 20%. I use Norton Antivirus (because it gives 60 days of free use when I newly install WIN11). When...
