Uptime and power
Laptops sleep, desktops lose electricity, updates reboot Windows at bad times. A data-centre VPS runs on redundant power. That alone stops most “EA stopped overnight” incidents.
Latency and location
Your home may be thousands of kilometres from the broker matching engine. A Singapore or Tokyo VPS shortens that path for Asian venues. Scalping and news strategies notice first; swing traders care more about uptime than 2 ms.
Operational workflow
With a VPS you RDP in to configure, then disconnect. Trading continues without an open laptop. From a café or phone you can still check charts. On a home-only setup you must leave the machine on and unlocked-session careful.
Cost mindset
A VPS is a small monthly infrastructure cost versus the risk of missed trades or unmanaged drawdowns when an EA dies mid-session. Size the plan to terminal count — do not overbuy CPU you will not use.
When home PC is enough
Manual trading during your waking hours, demo practice, or strategies that tolerate downtime can stay local. Move to a VPS when you enable AutoTrading overnight, add more terminals, or need stable SEA/Japan ping.
