Generally speaking, the less you turn a computer off and on, the better it is for the machine. It’s a different matter that human beings should take breaks from staring at computers all day though.
Might if trader using ea hence they need running ea 24 hour nonstop, but it’s mean they not must turn on computer nonstop, because they can hire vps and can running ea through vps, but manual trader might rarely they turn on computer 24 hour, like as me only using computer if having time to online
But are you capable of sitting at your computer 24/7?
It’s not necessary to sit at the computer to run it round-a-clock 
I’m still on the same machine as about 5 years ago (only upgraded from time to time) and it usually runs 24/7 with the occasional time in sleep mode.
I used to be worried about this as well, but now after it running reliably for so long, I’m not anymore obviously.
I used to be worried about it as well, and then people who knew more about the matter told me that it’s actually better for the machine that way. One should still run proper maintenance on the computer though - make sure it’s clean, that the fans are working properly, etc.
How has this thread got so many comments - who gives a flying ‘F’ if a pc is left on. They don’t suddenly erupt into flames, it’s 2016 guys, it’s not like the first PC came out last week! haha
I’ve run my PC for 24 hours for 5 days before and it wasn’t a problem. I then turned it off at the weekend. If you’re running an EA on a windows PC then be aware that an “Windows Update” could happen at any time and if you don’t postpone it then it will shut down your PC and restart but your PC might not re-start the EA
Thanks a lot Jezz…took your advice and look what happened:o

haha - ok that made me laugh! Good one!
Sure, just make sure it doesn’t overheat 
Yes you can, my computer is running everyday
It is not positive approach that we should keep open our desktop 24 hours a day continuously for a week, dear no doubt forex market opens 24 hours in the whole week but we should work in selected time in order to avoid the bad scenario, never stick with computer all the time.
Well there is a difference between running computer everyday and keeping it run for 24 hours continuously.
My laptop runs 24/5. Run maintenance on Saturday for an hour or so and then turn off till on Monday!
TBH if I need my PC to work 24/5 because of any expert advisor I would prefer to pay 25-30$ per month for a VPS so I don’t have to think about overheating, power cuts, automatic restarts because of any updates etc.
Powercuts can be a problem, but a computer with a proper fan and heatsink shouldn’t overheat. As for the update, you can always change the setting to choose when your computer should update itself.
Yeah dianajs I agree with you. You could also buy a UPS to avoid issues with power cuts. Maybe there is also a way to prevent internet issues of your internet provider. In the end, there are too much factors you should be on the alert for and one easy solution for all of them (or at least minimizing the risk).
P.S. I am not a VPS provider Lol and I don’t use VPS. I am just expressing my opinion on the topic
It depends on what you are doing at that time, you could just sit in with your trades open and doing nothing else, nothing would happen to the computer so there is constant power supply. I say this because we know with a desktop computer there might be lose of current memory when there is power interruption.
hehe. did you really
i am an I.T. Specialist
i’m an Engineer Actually
this is not technically accurate information that you have been given.
it depends on a few things.
firstly
a Windows computer cannot run indefinitely without being shutdown at some point,
a Linux Machine on the hand, can
then we consider where is your computer and how ventilated is it , or how hot or dusty does it get.
meaning… do you have it under a desk on the carpet with only 1 fan inside it and is it dusty as hell , and you never bothered to blow the dust out
or… does it have proper ventilation and adequate cooling.
beyond that computer specs come into it
also how many monitors do you have
what sort of power supply, what load capacity
where do you live in the world, how much power do you draw
but in short i can say this
i use both linux and Windows
my Windows system is running 6 Monitors
i have an i7 CPU
i have 16GB Ram
4 x 4TB Hard Drives
i use Active Cooling in my system , i have 1 CPU fan and 3 Case Fans
My computer is well ventilated as i check it for dust around once a month
i find i can keep my computer running for months without issue
but as a general rule of thumb
if my windows system is running for 3 days 24/7 or 24/3 if your prefer
i will restart it
but on a day to day trading basis, i like to screen record my trades
and i let the recording software run overnight while i’m sleeping
so the system is ON 24 hours literally
in the morning, i grab my coffee
i stop the recording
i restart the computer and i start trading again
so… i like to restart it every day if possible
but 3 days max
oh also,
over night, i turn off my monitors
now my linux system has 2 monitors, and similar hard ware to the last system
same deal
every day if possible
but i know with the linux system i can leave it and nothing will happen
the majority of my trading happens from the linux computer ,
the windows computer is mainly for news and calenders and emails and other stuff that i don’t to be part of trading or the recording on the screen
