AmiBroker server requirements
How Real-Time Data Plugins Change AmiBroker Server Requirements
Real-time data plugins turn AmiBroker into a continuously active market-data workstation. The right server depends on symbol count, update frequency, database writes and whether you also run scans, alerts or automated analysis.
Quick answer
AmiBroker real-time data plugins usually make network stability, single-core responsiveness, RAM headroom and fast storage more important than simply adding virtual CPUs. A Windows VPS suits a small watchlist and light charts; move to a dedicated server when many symbols, frequent updates, continuous writes and analysis jobs compete for the same resources.
What a real-time plugin adds to the workload
A plugin receives a live feed, maps fields to AmiBroker symbols and pushes updates into the application. AmiBroker may then refresh charts, formulas, explorations, alerts and recorded data. Each layer adds a different server constraint.
Feed and connection
Persistent connections need reliable networking, correct firewall rules and a stable Windows session. Low ping can help responsiveness, but it cannot compensate for feed outages.
Updates and calculations
Frequent ticks can trigger formula recalculation and chart refreshes. Fast CPU response and efficient formulas matter when work is lightly parallelized.
Database and history
Recording bars or ticks creates ongoing writes. NVMe storage and free disk space help keep databases, logs and temporary files responsive.
Monitoring and automation
Scans, alerts, exports and scripts consume resources beside the feed. Size for tasks that run at the same time.
Which server resources matter most?
| Resource | Why it matters | What to check |
|---|---|---|
| CPU | Formula recalculation, scans and alerts run beside the feed. | Prefer consistent dedicated CPU; profile formulas before adding cores. |
| RAM | Databases, charts, caches and applications remain in memory. | Leave headroom for Windows, AmiBroker, the plugin and RDP. |
| NVMe | Historical data, updates, logs and backups create I/O. | Keep free capacity and a separate backup routine. |
| Network | The feed needs a persistent, predictable connection. | Check route stability, firewall permissions and reconnect behavior. |
Practical sizing guide for AmiBroker
Plugin vendors differ in symbols, fields, update rates and storage behavior. Use these as starting points, then observe CPU, memory, disk activity and reconnect logs during your busiest session.
| Workload | Starting point | Scale up when |
|---|---|---|
| Small watchlist | Windows VPS, 2–4 vCPU, 8 GB RAM, NVMe. | Charts lag, feed reconnects or scans overlap. |
| Several markets and scans | 4–8 high-performance vCPU, 16 GB RAM. | CPU stays high or memory pressure appears. |
| Broad universe or intensive analysis | Dedicated Windows server, 16+ high-performance cores, 32 GB+ RAM and NVMe. | Feeds, databases and research tools compete continuously. |
These are capacity starting points, not guarantees. Let the plugin documentation and your actual symbol/update mix determine final sizing.
Practical setup checklist
- Confirm vendor support for your Windows version and plugin mode.
- Install AmiBroker and the plugin in a test workspace first.
- Configure Windows power and update policies for unattended hours.
- Allow only required feed traffic through the firewall.
- Keep databases, logs and backups organized on NVMe.
- Monitor CPU, RAM, disk activity and reconnects during peak load.
- Document symbol mappings, time zones and recovery steps.
- Test restart and reconnect behavior before relying on alerts.
When a VPS is not enough
A VPS is sensible for a small AmiBroker workspace because it provides an always-on Windows environment. It becomes a poor fit when shared CPU is saturated, disk activity is unpredictable or continuous tasks compete with the feed.
Consider a dedicated server when:
- you monitor a broad universe or several markets;
- real-time updates run beside heavy scans, explorations or exports;
- you need predictable CPU and storage for repeatable research;
- you run AmiBroker with MetaTrader terminals or StrategyQuant X.
For ordinary terminals and Expert Advisors, compare MetaTrader VPS plans. For heavier always-on use, review dedicated servers for MetaTrader. For separate MT5 optimization, use an EPYC backtest farm for MT5 Strategy Tester.
Troubleshooting real-time AmiBroker workloads
Charts or formulas lag
Review formula complexity and per-process CPU. If one core is saturated, more vCPUs may not solve the issue.
Feed disconnects
Check credentials, firewall rules, reconnect logs and route stability before blaming server capacity.
Database writes slow down
Check free space, rotate logs and schedule large backups outside the busiest update window.
RDP looks frozen
Check AmiBroker status, plugin logs and server counters; display lag is not always a feed failure.
Decision support: choose by the busiest hour
Start with the smallest environment that leaves measurable headroom during your busiest data and analysis window. Choose a dedicated Windows server when isolation and predictable resources matter more than the lowest monthly footprint. Before ordering, note your plugin, symbols, update frequency, databases, concurrent scans, terminals and RDP users.
FAQ
Do real-time AmiBroker plugins need a dedicated server?
Not always. A Windows VPS is usually sufficient for a small watchlist, light charts and limited scans. A dedicated server becomes more appropriate when many symbols, frequent updates, continuous database writes and heavy analysis run together. Measure the busiest workload first because plugin behavior varies by vendor and configuration.
How much RAM does AmiBroker need with a live data feed?
There is no universal number. A small workspace may start with 8 GB, while broader databases, multiple charts and concurrent scans can justify 16 GB or more. Leave RAM for Windows, the plugin, RDP and other trading tools. If memory pressure causes paging, add RAM or reduce simultaneous work.
Is CPU core count or single-core speed more important?
It depends on the workload. Live updates and some formulas can be sensitive to single-core responsiveness, while parallel scans benefit from more cores. Consistent dedicated CPU is often more useful than a large shared vCPU number. Profile actual formulas and scans before choosing a larger server.
Does low network latency guarantee better AmiBroker data?
No. Low latency can reduce transit time, but feed quality also depends on the vendor, route stability, packet loss, reconnect handling and permissions. A stable connection with correct configuration matters more than chasing one latency number.
Should AmiBroker data and backups share the same disk?
They can share storage on a small setup, but backups should not saturate the disk during the busiest update period. Keep free space, rotate logs and schedule large backups for quieter hours. Heavier workloads benefit from fast NVMe and a separate backup destination.
Can I run AmiBroker and MetaTrader on one Windows server?
Yes, if the server has enough CPU, RAM, storage and network headroom. Watch terminal count, Expert Advisors, charts, scans and writes together. A dedicated MetaTrader server is worth considering when the live-data workspace must remain responsive.
