A VPS is a virtual private server. A forex robot VPS will allow you to run a forex robot 24/7 without needing your computer running. usually when running a forex robot you would need the MetaTrader 4 trading terminal open on your computer all of the time. Now this may not be possible for many reasons so if it is not, you can pay a small fee every month from around just $15 for a very basic VPS. What the VPS will do is give you another remote windows installation where you can install and run MetaTrader 4 trading terminal 24/7 and therefore have your forex robots running at all times. A VPS is easily accessed from your computer using your browser or remote desktop connection. Most Forex VPS providers will offer rolling 1 month contracts and will very rarely if at all have any down time. You can even set them to fire up MetaTrader 4 automatically in the event of a rare crash. Whilst there are no specific specifications you need for a Forex VPS at the minimal you would want a decent processor and amount of RAM. This will allow you to run MetaTrader 4 on there with ease. If you want to run multiple installations of MetaTrader 4 then you should consider paying a little bit extra for a better spec VPS in terms of processor and RAM.
