A VPS — Virtual Private Server — is a dedicated remote computer that runs MetaTrader continuously, 24 hours a day, seven days a week. For any trader running an automated EA, it is the single most important infrastructure decision after choosing the EA itself.
This article explains exactly what a VPS does, why running an EA without one is a significant operational risk, and the specific criteria that matter when selecting a VPS provider for forex trading.
What a VPS Actually Is
A VPS is a slice of a physical server — a computer running in a data center — that you access remotely via internet. For forex trading, you install MetaTrader on the VPS, configure your EA, and then the EA runs continuously regardless of whether your personal computer is on.
The VPS stays connected to the internet with enterprise-grade uptime. Power failures, internet outages, and computer restarts on your end do not affect its operation.
What Happens Without a VPS
Without a VPS, the EA stops trading whenever your computer is off, sleeping, or loses internet connection. This creates specific risks:
- A recovery cycle in progress has open positions that need to close — if MetaTrader disconnects, the positions stay open but the EA cannot manage them
- A trading signal fires while your computer is off — missed entry that may not recur
- A stop condition (kill switch, news filter) needs to activate — but cannot without a running instance
The Worst-Case Scenario
A martingale EA is mid-recovery with five open positions. Your internet goes down overnight. The positions cannot close because MetaTrader disconnects. The market continues moving against the cycle. When you reconnect in the morning, the positions are at a much larger loss than when you left.
What to Look For in a Forex VPS
Location: As Close to Your Broker as Possible
VPS latency to the broker server affects execution speed. Most major forex brokers host servers in London (LD4 Equinix), New York (NY4 Equinix), or Tokyo. Choose a VPS provider with servers in the same location. A VPS in London connecting to a broker in London will have 1-2ms latency; a VPS in Bangkok connecting to London will have 200ms+.
Specifications: Minimum Requirements
For running 1-3 MT4/MT5 instances with EAs: 2GB RAM minimum (4GB preferred), 2 CPU cores, 50GB storage, Windows Server 2019 or 2022. More EAs or complex systems need more RAM.
Uptime: 99.9% Minimum
Look for providers that guarantee 99.9% uptime with SLA. This translates to under 9 hours of downtime per year. Enterprise data center providers typically achieve 99.95-99.99%.
Cost Expectations
A reliable forex VPS costs $15-40 per month depending on specifications and location. Cheaper options exist but often compromise on location quality or uptime guarantees. For a system running $1,000+ in capital, the $20/month VPS cost is a negligible operational expense.
Some brokers offer free VPS hosting to clients above a certain balance or trading volume threshold — worth checking before paying for a third-party provider.
