Mastering Multiple MT4/MT5 Terminals on a VPS
Run many terminals safely on one Windows VPS: isolated data folders, clean autostart, right-sized CPU/RAM—no cross-talk, no surprises.
Why Use a VPS for MT4/MT5?
A trading-grade VPS gives stable power/network, closer proximity to brokers, and 24/7 uptime—perfect for multiple terminals and EAs without desktop interruptions.
Choose the Right VPS Provider
What to look for
- Dedicated CPU/RAM (no noisy neighbors)
- NVMe SSDs & Tier-1 network
- Regions near major FX hubs
Built for MT
WinServers.NET offers MT4/MT5-tuned Windows VPS & Dedicated with preconfigured security and low-latency peering.
Safe Setup & Data-Folder Isolation
Never let terminals share state. Install each instance into its own directory and point it to a unique data folder.
Folder Layout (example)
C:\MT4\BrokerA\
C:\MT4\BrokerB\
C:\MT5\BrokerC\
# Unique data directories
C:\MT-Data\BrokerA\
C:\MT-Data\BrokerB\
C:\MT-Data\BrokerC\Launch with explicit data dirs
# MT4 / MT5 accept /portable or explicit data path switches.
# Prefer explicit data path per instance:
Start-Process "C:\MT4\BrokerA\terminal.exe" -ArgumentList '/datapath="C:\MT-Data\BrokerA"'
Start-Process "C:\MT4\BrokerB\terminal.exe" -ArgumentList '/datapath="C:\MT-Data\BrokerB"'
Start-Process "C:\MT5\BrokerC\terminal64.exe" -ArgumentList '/datapath="C:\MT-Data\BrokerC"'/portable keeps data inside the install folder; /datapath is clearer and scales better.
CPU & RAM Sizing
| Terminal Count | Recommended CPU | Recommended RAM | Notes |
|---|---|---|---|
| 1–2 | 1 vCPU | 2–3 GB | Light EAs/indicators |
| 3–5 | 2 vCPU | 4–6 GB | Moderate charts/EAs |
| 6–10 | 4 vCPU | 8–12 GB | Heavier workloads |
| 10+ (pro) | 6–8 vCPU | 16–24 GB | Consider Dedicated |
Monitor with Task Manager/Resource Monitor and scale before hitting 70–80% sustained CPU or RAM.
Auto-Start Scripts
Quick .bat
@echo off
start "" "C:\MT4\BrokerA\terminal.exe" /datapath="C:\MT-Data\BrokerA"
start "" "C:\MT4\BrokerB\terminal.exe" /datapath="C:\MT-Data\BrokerB"
start "" "C:\MT5\BrokerC\terminal64.exe" /datapath="C:\MT-Data\BrokerC"Task Scheduler (resilient)
# Create a scheduled task to launch on logon & on startup
$action = New-ScheduledTaskAction -Execute "C:\Scripts\start-mt.bat"
$trigger1 = New-ScheduledTaskTrigger -AtLogOn
$trigger2 = New-ScheduledTaskTrigger -Once -At (Get-Date).AddMinutes(1) -RepetitionInterval (New-TimeSpan -Minutes 5) -RepetitionDuration ([TimeSpan]::MaxValue)
Register-ScheduledTask -TaskName "Start-MT-Terminals" -Action $action -Trigger $trigger1,$trigger2 -RunLevel HighestSet “Run whether user is logged on or not” and “Restart on failure”.
Best Practices
Process Hygiene
- One EA per chart; avoid duplicate tick processing.
- Disable Windows sleep/hibernation; auto-reboot weekly off-hours.
Networking
- Host near your broker; target <10 ms (FX) / <50 ms (crypto).
- Whitelist broker IPs in firewall; block all else inbound.
Backups & Logs
- Daily backup of
MQL4/5, profiles, and logs. - Keep separate log folders per instance for faster support.
Conclusion
Multiple MT4/MT5 terminals on one VPS are easy—if you isolate data, size resources correctly, and automate startup. Do that, and your stack stays clean, stable, and fast.
