Size a VPS for the applications, charts, history and automation it runs, not the number of account rows alone. Several accounts in one RTrader session can require less computing work than several separate charting applications. Measure the intended workload before selecting resources.
Educational software guidance. Trading involves risk. Read the financial and information disclaimers.
Inventory the workload
List each platform, supported connection, chart count, instrument subscription, historical-data load and locally managed strategy/copier. Record which applications depend on RTrader Pro plugin mode. A cloud receiver and a local desktop strategy have different hosting requirements.
Measure before buying more capacity
| Measurement | Interpretation |
|---|---|
| CPU during market bursts and history load | Identifies sustained processing pressure; one busy core can matter |
| Committed memory and paging | Helps distinguish adequate RAM from disk-backed memory pressure |
| Disk free space and write activity | Logs/history can fill a small disk |
| Quote timestamps and application response | Helps separate remote-display lag from delayed platform processing |
| Connection and order records | Required to investigate routing delays; an RDP impression is insufficient |
Use Windows Task Manager on the actual intended workload and keep headroom for bursts and updates. There is no verified universal rule that each account needs a fixed amount of RAM or that a Chicago VPS delivers one-millisecond orders.
Organize sessions and recovery
Use only platform-supported connection combinations. Do not bypass single-instance or data-session restrictions with copied installations. Keep account IDs distinct from connection labels and review each destination's state.
Keep the operating system supported, secure remote access, back up configurations and plan updates outside the intended trading session. Disconnecting an RDP viewer, signing out of Windows, rebooting and terminating a platform are different actions. Check which local order-management components would stop before ending the session.
Rithmic's desktop requirements describe Windows compatibility; they do not size a multi-platform workload. Compare current hosting quotes including Windows licensing, backups and management. Add software, data and copier fees separately for the actual intended configuration.

Common questions
Does adding an account require another VPS?
Not inherently. It depends on the supported connection and workload.
Does a VPS prevent all disconnects?
No. Host, network, provider and application failures remain possible.
Should I leave RTrader running for plugin clients?
The supported plugin host must remain available to its clients.
Does cloud alert routing need my own VPS?
A cloud receiving service may host that path, but any separate local strategy or platform still needs its own host.
