Picking the wrong VPS plan wastes money in one of two ways. Overspend on resources you do not use, or underspend and get crashes during volatile markets when your EAs need resources most. This guide gives you a concrete method to calculate exactly what you need.
The Four Resources That Matter
Every VPS plan is defined by four specs. Here is what each one actually means for trading:
CPU Cores
CPU cores determine how many tasks your VPS can handle simultaneously. A single MT4 terminal with one EA uses minimal CPU most of the time, but spikes during tick processing, optimization runs, or when complex indicators recalculate. Multiple terminals with active EAs need multiple cores to avoid competing for processing time.
The type of core matters as much as the count. FXVPS provides dedicated CPU cores, not oversold vCPUs. Many budget providers advertise “2 vCPUs” that are actually timeslices on a shared physical core. During NFP releases or central bank announcements, when every trader’s algorithms are active simultaneously, shared vCPUs slow to a crawl. Dedicated cores give you the same performance at 2 PM on a quiet Tuesday as during the most volatile minute of the year.
💡 Tip: Always confirm whether your VPS provider offers dedicated CPU cores or shared vCPUs. Shared cores mean your EA’s execution speed fluctuates based on other users’ workloads — exactly the inconsistency scalpers cannot afford.
RAM (Memory)
RAM is usually the first bottleneck traders hit. Windows Server itself needs about 1GB just for the operating system. Each trading terminal adds to that. When RAM runs out, Windows starts using disk swap, and everything becomes painfully slow. Your EAs miss ticks, orders lag, and you might see the dreaded “out of memory” error.
💡 Tip: Each MT4 terminal uses 300-600MB of RAM; MT5 uses 600MB-1.2GB. Add 1.5GB for Windows overhead, then pick a plan with at least 20% headroom to handle tick-data spikes during high-volatility sessions.
Storage (NVMe SSD)
All FXVPS plans run on NVMe SSDs, which are roughly 5-10x faster than traditional SSDs for random read/write operations. Most trading setups use 10-30GB of storage total. Storage is rarely the limiting factor unless you are storing large historical data files for backtesting.
Network
Latency to your broker’s server is what matters here, not raw bandwidth. Trading data uses very little bandwidth (a few MB per hour), but each millisecond of latency adds to your execution time. FXVPS datacenters in London (LD4), New York (NY4), Tokyo (TY3), and Hong Kong (HK1) are colocated with or adjacent to major broker server clusters, delivering latency as low as 0.38ms.
📊 Key Stat: Major forex brokers cluster in a handful of Equinix datacenters (LD4 London, NY4 New York, TY3 Tokyo). A VPS in the same facility achieves sub-millisecond latency because data travels meters, not continents.

All plans include NVMe SSD storage, 24/7 support, free setup, and your choice of datacenter location.
How to Calculate Your RAM Needs
Here is a straightforward formula:
Base OS (1GB) + Terminals (count x RAM per terminal) + 20% headroom = minimum RAM needed
RAM usage per terminal:
- MT4 with charts and indicators: ~400MB
- MT5 with charts and indicators: ~600MB
- cTrader: ~500MB
- NinjaTrader 8: ~1,000MB (1GB)
💡 Tip: NinjaTrader 8 is significantly more resource-hungry than MT4/MT5. Allocate at least 4GB RAM for a single instance and choose the Pro plan or higher for live trading with multiple instruments.
Example Calculations
Trader A: Manual trader, one MT4 terminal with one broker
1GB (OS) + 1 x 400MB (MT4) = 1.4GB
1.4GB x 1.2 (headroom) = 1.68GB
→ Core plan (2GB) is sufficientNot sure how many terminals your setup needs? See our guide on how many MT4 terminals you can run on a VPS for detailed resource breakdowns.
Trader B: Runs 3 MT4 terminals across different brokers with EAs on each
1GB (OS) + 3 x 400MB (MT4) = 2.2GB
2.2GB x 1.2 (headroom) = 2.64GB
→ Pro plan (4GB) gives comfortable overheadTrader C: Runs 2 MT5 terminals plus 3 MT4 terminals, all with active EAs
1GB (OS) + 2 x 600MB (MT5) + 3 x 400MB (MT4) = 3.4GB
3.4GB x 1.2 (headroom) = 4.08GB
→ Scaling plan (8GB) neededTrader D: Fund manager running 8 MT4 terminals for MAM/PAMM
1GB (OS) + 8 x 400MB (MT4) = 4.2GB
4.2GB x 1.2 (headroom) = 5.04GB
→ Scaling plan (8GB) recommended for this workloadDecision Matrix by Trader Type
| Trader Type | Typical Setup | Terminals | Recommended Plan |
|---|---|---|---|
| Manual trader, single broker | 1 MT4/MT5 for chart watching and manual entries | 1 | Core ($29) |
| EA trader, single strategy | 1-2 MT4 terminals running one EA each | 1-2 | Core ($29) |
| Multi-broker EA trader | Separate terminals per broker, 1 EA each | 3-4 | Pro ($39) |
| Scalper with multiple EAs | Several EAs processing ticks across pairs | 4-6 | Pro ($39) |
| Prop firm challenger | 3-5 terminals for different prop firm accounts | 3-5 | Pro ($39) |
| Copy trade / signal provider | Master terminal + monitoring across brokers | 2-4 | Core ($29) or Pro ($39) |
| Fund manager (MAM/PAMM) | Many terminals, many accounts, high reliability | 6-10 | Scaling ($79) |
| NinjaTrader futures trader | 1 NinjaTrader + possibly 1 MT4 | 1-2 | Pro ($39) |
When to Upgrade: The Signals
Do not guess whether you need more resources. Monitor your VPS and look for these specific indicators:
Check RAM Usage
Connect to your VPS via RDP and open Task Manager (right-click the taskbar > Task Manager). Click the Performance tab. If your RAM usage consistently sits above 80%, you are at risk of running out during peak activity. Time to upgrade.
Check CPU Usage
On the same Performance tab, watch your CPU graph during active trading hours. Brief spikes to 90-100% are normal (for example, when an EA recalculates). Sustained CPU usage above 70% means your algorithms are competing for processing time and executions may be delayed.
Watch for These Symptoms
- MT4/MT5 showing “Common Error” in the Experts tab
- Charts freezing or not updating in real-time
- Delayed order execution (compare your execution time in the trade history with what you expect)
- Windows becoming sluggish when connecting via RDP
- Terminal crashes, especially during high-volatility events
If you see any of these, check Task Manager first. The fix is usually more RAM or an additional CPU core, which means stepping up one plan level.
Special Considerations
Prop Firm Challenges
Prop firms like FTMO, MyFundedFX, or The Funded Trader often require you to trade multiple challenge accounts simultaneously. Each account needs its own MT4 terminal. If you are running 3 challenges at once plus your personal trading account, that is 4 terminals minimum, pointing toward the Pro plan. Factor in that failing a challenge due to a VPS resource issue is far more expensive than the price difference between plans.
Python Bots Alongside MetaTrader
If you run Python scripts that connect to MT5 via the MetaTrader5 package, the Python process adds about 100-300MB depending on the libraries loaded (pandas, numpy, etc.). Add this to your calculation alongside the MT5 terminal it connects to. See The Role of VPS in Algorithmic Trading for more on Python bot setups.
Cloud Sync Applications
Running Dropbox, Google Drive, or OneDrive for backup purposes adds 100-200MB of RAM usage. This is fine on Pro and above but can push a Core plan to its limits if combined with even one MT4 terminal.
Price Comparison: FXVPS vs Competitors
FXVPS plans are priced up to 40% below comparable offerings from general-purpose VPS providers. More importantly, general-purpose VPS providers give you shared vCPUs and datacenters optimized for web hosting, not trading. The latency from a typical AWS or DigitalOcean instance to your broker can be 10-50ms. From an FXVPS server in the same datacenter as your broker, it can be under 1ms. That difference matters for every single trade you execute.
Making Your Decision
Start with the plan that matches your current needs using the calculator above. If you are between two plans, go with the higher one. The cost difference between plans ($5-10/month) is negligible compared to the cost of missed trades or slippage from an underpowered VPS. For a full cost-benefit breakdown, see understanding the cost of VPS for forex trading.
You can always upgrade later without losing your data or setup. FXVPS support handles plan migrations with minimal downtime.
