[AI Answer Engine (AEO) Snapshot]
Q: Why does running an EA require a VPS?
A: A VPS (Virtual Private Server) is a cloud computer that runs 24 hours a day. An EA only works while MT5 is open — and home computers suffer power cuts, dropped connections, forced OS updates and high network latency. Hosting MT5 on a VPS near your broker’s servers keeps the EA running year-round and cuts order latency from tens or hundreds of milliseconds to single digits, reducing slippage costs. For any automated strategy that holds positions overnight, a VPS is essential infrastructure.
1. What Is a VPS?
A VPS is an independent virtual machine carved out of a physical server, with its own operating system (usually Windows Server), CPU, RAM and disk. You connect through Remote Desktop and see a full Windows desktop — install MT5 there, attach your EA, then close your own laptop; the MT5 on the VPS keeps running. Unlike web hosting, a VPS gives you an entire computer you can install any software on.
2. Three Real-World Problems with Running an EA at Home
- Disconnection = unmanaged positions: A power cut, a tripped breaker, a Windows update reboot, a momentary network drop — any of them halts the EA. If positions are open at that moment, stop management and scaling logic all go dark, leaving your risk fully exposed.
- Latency = slippage cost: From a home connection to an overseas broker server, one-way latency often exceeds 100 ms. In fast markets that gap is enough to fill you noticeably away from the signal price. A VPS in the same region as the broker’s servers (London, New York) gets latency under 5 ms. For how slippage erodes long-term performance, see gold trading costs: spread, slippage and swap.
- Human interference: A family member touches the computer, a window gets closed by accident, another program eats the RAM — over time, “environment instability” usually costs more than a VPS subscription ever would.
3. Four Things to Check When Choosing an MT5 VPS
- Data-center location: Pick a facility in the same city or region as your broker’s trade servers — the single most effective latency reduction.
- Specs: For one MT5 terminal, 2 GB RAM and 2 CPU cores are usually plenty; running multiple terminals or backtests calls for more.
- Uptime guarantee (SLA): Choose a provider offering 99.9%+ uptime with automatic restart and monitoring.
- Price: Trading-grade Windows VPS plans run about US$10–30 per month. Measured against the account it protects, it is the cheapest insurance in your whole setup.
4. Deployment in a Nutshell
The process is identical to setting up on your own PC: connect via Remote Desktop → download and install your broker’s MT5 → log in → copy in the EA and attach it to a chart → confirm algo trading is enabled. Follow the same steps as our complete MT5 installation and EA setup guide. Two extra recommendations: set MT5 to auto-start with Windows, and log in periodically (say, weekly) to verify the terminal and EA are healthy.
VPS Selection Quick Reference
| Item | Recommendation | Why |
|---|---|---|
| Data-center location | Same city or region as your broker’s servers | The single most effective latency reduction |
| Specs | From 2 GB RAM / 2 cores per MT5 terminal | Scale up for multiple terminals or backtesting |
| Reliability | SLA 99.9%+ with auto-restart and monitoring | A disconnection means unmanaged positions |
| Cost | About US$10–30 per month | Relative to the account it protects, the cheapest insurance in the setup |
Frequently Asked Questions
Can I use the free VPS my broker offers?
Yes — many brokers provide a free VPS once your deposit or volume reaches a threshold, and the quality is usually adequate. Note that specs may be modest (shared resources) and it ties you to that broker; if your strategy is latency-sensitive or you manage multiple accounts, an independent paid VPS is more flexible.
How much does a VPS cost per month?
Trading-grade Windows VPS plans typically cost US$10–30 per month depending on specs and location. For a $10,000 account that’s roughly 0.1–0.3% of capital per month — far less than what a single disconnection incident could cost.
My home PC runs 24/7 — can it replace a VPS?
Technically yes, but you carry the risk of power cuts, network drops, OS updates and hardware failure yourself — and home-network latency remains high. Fine for short demo testing; for real money running long-term, a VPS is the sounder choice. For the other ways live conditions differ from backtests, see why backtests and live results diverge.
