Your automated strategy is connected to Trader Workstation when your home router restarts or Windows enters sleep mode. The strategy loses its API connection, new market data stops arriving, and an order-management action may not reach Interactive Brokers. An Interactive Brokers VPS is useful when TWS, IB Gateway, or an API strategy must remain active beyond the reliability of your home computer.
Manual traders can use Interactive Brokers without remote hosting. The requirement changes when a local application must process market data, maintain an API socket, or trade across several global market sessions.
This guide explains when an Interactive Brokers VPS is useful, whether to run TWS or IB Gateway, which resources to allocate, how IBKR restarts affect automation, and how to test the complete setup before trading live.
Does Interactive Brokers Require a VPS?
Interactive Brokers does not require a VPS, since Trader Workstation can run on a supported desktop computer. However, a VPS is recommended when an IBKR API strategy or continuously running trading application must remain connected without depending on your home PC, power, or internet.
Trader Workstation, or TWS, is IBKR’s full desktop trading platform. IB Gateway is a lighter application that provides the same socket connection for API software without loading the complete TWS trading interface.
The TWS API is a TCP socket interface that connects an automated application to a running instance of TWS or IB Gateway. The strategy does not connect directly to the IBKR brokerage system through the TWS API, so closing the host application breaks the local API path. (Source: IBKR TWS API Introduction, 2026).
| IBKR setup | Is a VPS required? | Main consideration |
| Manual TWS trading while present | No | The trader can respond to local problems |
| Client Portal or mobile monitoring | No | No continuously running desktop application is required |
| Basic portfolio review | No | Persistent API connectivity is unnecessary |
| Automated TWS API strategy | Recommended | TWS or IB Gateway must remain active |
| Third-party platform connected through TWS | Recommended | The integration depends on the local socket connection |
| Trading several global sessions | Recommended | The application must remain available for longer periods |
| Overnight order monitoring | Recommended | A home shutdown can interrupt local management |
| Several trading applications | Strongly recommended | Dedicated CPU, RAM, and uptime become more important |
A VPS removes home-side failure points. It does not remove IBKR maintenance periods, weekly authentication, broker-side restrictions, exchange outages, or strategy errors.
Which Interactive Brokers Setups Benefit Most From a VPS?
Automated API strategies, third-party platform integrations, and systems that trade across several market sessions benefit most from an Interactive Brokers VPS. These setups require a stable Windows environment even when the trader is away from the screen.
The strongest use case is a process that must receive data or submit instructions without manual supervision. A VPS keeps the process running, but the application must still handle disconnections and reconcile its state after IBKR maintenance.
| Trading setup | VPS benefit | Main dependency |
| Python, Java, C++, C#, or Visual Basic API strategy | Maintains the socket connection | TWS or IB Gateway |
| Bookmap or another third-party platform | Keeps the integration available | API-enabled host application |
| Global equity trading | Supports several regional sessions | Continuous platform operation |
| Overnight futures monitoring | Removes home power dependence | Data and order connectivity |
| Portfolio automation | Maintains scheduled calculations | Strategy process |
| Several API clients | Provides dedicated resources | CPU, RAM, and socket configuration |
| Alert and notification service | Keeps monitoring active | Market data and application uptime |
IBKR supports API implementations in Python, Java, C++, C#, and Visual Basic. TWS can support up to 32 simultaneous API client connections, although each client must use a unique client ID and follow account-level pacing limits. (Source: IBKR API Connection Setup, 2026).
Automated Strategies Using the IBKR API
An automated IBKR strategy depends on a local socket connection to TWS or IB Gateway. The strategy must detect when that socket closes and reconnect only after the host application has restored its IBKR session.
A complete API setup contains several independent processes:
- TWS or IB Gateway
- The strategy application
- Market data subscriptions
- Order and position synchronisation
- Connection monitoring
- Application logs
- Restart and recovery controls
The IBKR API VPS setup explains how a remote Windows environment can host IB Gateway, strategy code, and monitoring tools together. The setup still requires tested recovery logic for IBKR resets and authentication events.
The strategy should never assume that a missing acknowledgement means an order was rejected. It must query open orders, executions, and positions after reconnection before submitting a replacement.
Multi-Session and Overnight Trading
Multi-session trading means keeping one trading environment available across Asian, European, and North American market hours. It does not mean logging the same IBKR username into several competing trading sessions at once.
A competing session can disconnect TWS or IB Gateway from IBKR. The automated setup should use one designated session and avoid opening another trading application with the same username during active strategy operation.
A multi-session VPS is useful for:
- Asian market monitoring
- European cash and derivatives sessions
- North American equities and options
- CME futures trading
- Overnight risk checks
- Scheduled portfolio rebalancing
- Time-based API orders
Long operating hours increase the chance that the application encounters an IBKR reset. The strategy must therefore distinguish between a normal maintenance disconnection and an unexpected network failure.
Should You Run Trader Workstation or IB Gateway on the VPS?
Run TWS when you need full charts, order-entry tools, and visual account monitoring. Run IB Gateway when the VPS is dedicated mainly to API execution and does not need the full trading interface.
From the API application’s perspective, TWS and IB Gateway provide the same type of socket connection after authentication. IB Gateway uses about 40% fewer resources because it omits many of TWS’s visual trading tools.
| Feature | Trader Workstation | IB Gateway |
| API socket access | Yes | Yes |
| Full trading interface | Yes | No |
| Charts and analytical tools | Yes | Limited |
| Manual order entry | Full interface | Basic interface |
| Risk Navigator and BookTrader | Available | Not available |
| Relative resource use | Higher | About 40% lower |
| Suitable for manual monitoring | Yes | Limited |
| Suitable for dedicated API hosting | Yes | Preferred for lighter workloads |
| Graphical login required | Yes | Yes |
| Automatic daily restart | Available | Available |
IBKR states that both applications require a graphical login and do not support a completely headless session without a user interface. IB Gateway is lighter, but it still requires authentication and scheduled restart management. (Source: IBKR IB Gateway Documentation, 2026).
Beginning API users benefit from learning TWS first because its visual tools make positions, orders, market data, and connection states easier to inspect. A production strategy can later move to IB Gateway after its monitoring and recovery logic has been tested.
What Happens When TWS Loses Its Connection?
TWS stops exchanging data with IBKR when its brokerage connection is lost, while the local API application may remain connected to the TWS process. The strategy must read IBKR system messages to determine whether market data was preserved, lost, or restored.
IBKR uses system message codes to describe connection state. These messages are operational events rather than strategy-generated errors.
| Code | Meaning | Required strategy response |
| 1100 | Connectivity between IBKR and TWS was lost | Pause connection-dependent actions |
| 1101 | Connectivity restored, but data was lost | Resubmit market data requests |
| 1102 | Connectivity restored and data was maintained | Continue after state verification |
| 1300 | The configured socket port changed | Reconnect the API client on the new port |
IBKR states that clients are likely to experience at least one daily disconnection because of scheduled server maintenance. Native orders can continue operating during a reset, while execution reports and simulated orders may be delayed. (Source: IBKR System Message Codes, 2026).
The API strategy should perform a recovery sequence after every code 1101 event:
- Request current positions.
- Request open orders.
- Request recent executions.
- Resubmit required market data subscriptions.
- Compare broker state with the strategy state.
- Resume new order generation only after reconciliation.
A VPS reduces disconnections caused by the home environment. It cannot prevent scheduled or unexpected interruptions inside IBKR’s systems.
How Do IBKR Session Restarts and Reauthentication Affect Automation?
IBKR requires TWS and IB Gateway to restart regularly, so a VPS cannot keep one authenticated session running indefinitely. Configure automatic daily restarts and plan for a manual weekly authentication step.
IBKR recommends using Auto restart and Never lock Trader Workstation for supported API setups. TWS and IB Gateway can restart automatically during the week, but security credentials must be entered again after the weekly authentication cycle.
| Session event | Expected behavior | Automation requirement |
| Daily application restart | TWS or IB Gateway restarts automatically | Strategy reconnects after the socket returns |
| Daily IBKR maintenance | Brokerage connection drops temporarily | Strategy handles codes 1100, 1101, and 1102 |
| Weekly authentication | Manual authentication is required | Trader completes the login before automation resumes |
| Competing login | Existing session may disconnect | Avoid using the same username elsewhere |
| Windows sleep | API connection stops | Disable sleep on the VPS |
| VPS restart | All local applications close | Use a documented startup sequence |
| Failed auto update | Application may not restart correctly | Monitor the process after maintenance |
The relevant controls are located under Global Configuration > Lock and Exit. The weekly authentication cycle begins each Monday, and a failed soft-token login indicates that manual reauthentication is required. (Source: IBKR Daily and Weekly Reauthentication, 2026).
An automated strategy should send an alert when TWS or IB Gateway does not return after its expected restart window. Silent restart failures create more risk than a visible disconnection.
What VPS Specifications Work Best for Interactive Brokers?
A practical Interactive Brokers VPS should provide at least 2 fast vCPU cores, 8 GB of RAM, and SSD or NVMe storage for one moderate TWS setup. Use 16 GB or more when the server runs several charts, API clients, market data streams, or additional trading platforms.
IBKR lists 8 GB of RAM as the minimum for TWS and 16 GB as the recommended amount. Its Windows requirements specify an Intel i5 as the minimum processor and an Intel i7 or better as the recommended level.
| IBKR workload | vCPU | RAM | Storage | Suitable use |
| Lightweight IB Gateway and one strategy | 2 | 4 to 8 GB | 40 GB SSD | Basic API execution |
| Moderate TWS setup | 2 to 4 | 8 GB | 50 GB NVMe | Several watchlists and charts |
| TWS with several API clients | 4 | 16 GB | 80 GB NVMe | Market data and automated strategies |
| TWS with multiple trading platforms | 4 to 8 | 16 GB or more | 100 GB NVMe | Bookmap, charting, and API tools |
| Large portfolio or many charts | 6 or more | 16 to 32 GB | 120 GB or more NVMe | Heavy monitoring and analysis |
IBKR states that users with more than 500 stock positions, 100 options positions, or 15 chart windows may need to increase the memory allocated to TWS. Broadband connectivity is also listed as a minimum platform requirement. (Source: IBKR TWS System Requirements, 2026).
A Forex VPS plan can host IBKR-related API applications and other trading tools on a remote Windows environment. The correct plan depends on the total workload rather than the number of broker accounts alone.
Resources for a Basic TWS Setup
A basic TWS setup needs enough resources for Windows, Java, TWS, live market data, and normal remote administration. Eight gigabytes of RAM provides a safer baseline than sizing the server only for the application’s idle state.
Monitor these Windows Task Manager values:
- Total CPU usage
- TWS or IB Gateway CPU usage
- Available memory
- Java process memory
- Disk active time
- Network throughput
- Page file activity
TWS allows users to adjust application memory allocation. Assigning too much memory can create system-wide pressure when Windows and other applications no longer have enough available RAM.
Resources for APIs and Multiple Trading Applications
API strategies add processing, logging, database, and runtime requirements beyond TWS or IB Gateway. A Python strategy, Java service, Bookmap connection, and monitoring agent can each consume separate CPU and memory resources.
Increase resources when the server runs:
- Several API clients
- Multiple market data subscriptions
- Large position or order sets
- Third-party charting applications
- Databases or message queues
- Intensive historical-data processing
- Several broker platforms
- Development and production processes together
Separate development tests from live automation where practical. A backtest or code compilation should not compete with an active order-management process for the same CPU and memory.
Where Should an Interactive Brokers VPS Be Located?
Place the Interactive Brokers VPS near the IBKR server assigned to the TWS session, then test the actual network route. New York, Chicago, Zurich, and Hong Kong are relevant starting regions because IBKR assigns TWS connections to regional server infrastructure.
Open TWS and select Data to view the primary connected server. The location of the VPS should follow that endpoint rather than the trader’s physical address.
| IBKR connection region | VPS region to test | Common use |
| TWS America East | New York | US equities, options, and East Coast connectivity |
| TWS America Central | Chicago | US futures and central-region connectivity |
| TWS Europe | Frankfurt, Amsterdam, or nearby Europe | European sessions |
| TWS Asia | Hong Kong | Asian market connectivity |
| Asia-Pacific strategy with regional services | Singapore or Tokyo | Supporting regional applications |
| Several markets | Test multiple regions | Select the lowest stable route |
IBKR states that each account has a predetermined TWS server location. Live-account users can request a server-region change through a technical support ticket, while paper accounts connect to US infrastructure by default. (Source: IBKR Connected Server Location, 2026).
The API trading infrastructure guide explains how physical distance and carrier routing affect API connections. A nearby server with an indirect network path can perform worse than a slightly more distant server with better peering.
Location should be tested with repeated latency measurements. One ping result does not reveal route consistency, packet loss, or performance during active market periods.
Can a VPS Reduce IBKR Order Latency?
A VPS can reduce client-side IBKR order latency when it shortens the network path and provides faster local processing than the trader’s home computer. It cannot control IBKR risk checks, exchange routing, market liquidity, or the final execution price.
Latency is the time required for an instruction or response to travel between systems. The complete order path contains several separate latency stages.
| Order stage | Can the VPS affect it? | Main factor |
| Strategy calculation | Yes | CPU performance and code efficiency |
| API message creation | Yes | Application performance |
| Local socket transmission | Yes | Host resource availability |
| TWS-to-IBKR network route | Yes | VPS location and connectivity |
| IBKR order processing | No direct control | Broker infrastructure |
| SmartRouting or destination routing | No direct control | IBKR routing logic |
| Exchange processing | No direct control | Venue infrastructure |
| Market fill | No guarantee | Price and available liquidity |
A trading VPS should make the client-side order path stable and measurable, not promise a specific fill or profitable result.
Measure the time at strategy decision, API submission, TWS acknowledgement, order status update, and execution. A fill timestamp alone cannot identify whether a delay occurred in the strategy, network, broker, or market.
How Do Market Data Feeds Affect VPS Performance?
IBKR market data increases VPS workload according to the number of subscribed instruments, data types, and API requests. Large watchlists, market-depth feeds, real-time bars, and several API clients require more memory, processing, and message handling.
Market data lines represent active requests for streaming information. TWS watchlists and API applications share the username’s available lines.
| Data workload | Resource effect | IBKR limit or consideration |
| Level 1 quotes | Continuous updates | Uses market data lines |
| Level 2 depth | More frequent and detailed updates | Higher processing demand |
| Real-time bars | Repeated bar messages | Adds API callbacks |
| Large watchlists | More TWS display updates | Shares line allocation |
| Several API clients | Concurrent subscriptions | Uses the same account limits |
| Historical requests | Data transfer and processing | Subject to pacing rules |
| Frequent subscribe and cancel calls | Outbound API messages | Can trigger pacing violations |
IBKR provides 100 market data lines by default. A TWS watchlist displaying 50 instruments and one API client using 25 lines would leave 25 lines for another API connection. (Source: IBKR Market Data Lines, 2026).
The default pacing allowance is 50 API requests per second because the limit equals the number of market data lines divided by two. Exceeding the permitted rate can cause TWS to disconnect the API client. (Source: IBKR API Pacing Limitations, 2026).
Additional CPU or RAM cannot bypass an account-level market data or pacing limit. The strategy must manage subscriptions and message rates correctly.
How Do You Install TWS or IB Gateway on a Windows VPS?
Install TWS or IB Gateway by connecting to the Windows VPS through Remote Desktop, downloading the current installer from IBKR, and configuring the correct API socket settings. Complete the initial setup with a paper account before enabling live API orders.
Install only the applications required by the strategy. A smaller production environment is easier to monitor, secure, and restore.
| Step | Action | Required outcome |
| 1 | Connect to the VPS through Remote Desktop | The Windows desktop opens |
| 2 | Apply Windows updates | Current security updates install |
| 3 | Download TWS or IB Gateway from IBKR | The official installer is available |
| 4 | Complete the installation | The application opens without errors |
| 5 | Log in and complete two-factor authentication | The IBKR session becomes active |
| 6 | Open Global Configuration > API > Settings | API controls become available |
| 7 | Enable ActiveX and Socket Clients | The application accepts API connections |
| 8 | Review Read-Only API | Disable it only when API orders are required |
| 9 | Confirm the socket port | Strategy and host use the same port |
| 10 | Restrict trusted IPs | Only approved clients can connect |
| 11 | Configure Lock and Exit | Daily restart behaviour is defined |
| 12 | Connect the paper strategy | Data and orders pass the initial test |
The default socket ports are:
| Application | Live port | Paper port |
| Trader Workstation | 7496 | 7497 |
| IB Gateway | 4001 | 4002 |
IBKR enables Read-Only API by default, which blocks API order submission until the setting is cleared. The socket port in the strategy must match the port configured inside TWS or IB Gateway. (Source: Installing and Configuring TWS for the API, 2026).
Use 127.0.0.1 or localhost when the strategy runs on the same VPS as TWS or IB Gateway. Do not expose the API socket directly to the public internet unless the application architecture requires remote access and uses appropriate network controls.
How Can You Keep an IBKR Strategy Running After Closing Remote Desktop?
Disconnect the Remote Desktop session without signing out of Windows. TWS, IB Gateway, and the API strategy continue running inside the VPS session after the RDP window closes.
Remote Desktop is the interface used to view and control the server. It is not the process that runs the trading applications.
| Remote action | Effect on the IBKR setup |
| Close the RDP window | Applications normally continue running |
| Select Disconnect | Applications continue running |
| Lose home internet | VPS applications remain active |
| Lock the VPS session | Applications remain active |
| Select Sign out | Applications close |
| Restart Windows | Applications stop during the restart |
| Shut down the VPS | The complete setup stops |
| Provider ends the session | Applications may close |
Microsoft states that disconnecting an RDS user leaves all applications running on the remote server. (Source: Microsoft Disconnect-RDUser, 2026).
Closing RDP does not prevent IBKR’s daily resets or weekly authentication requirement. Monitoring should alert the trader when TWS, IB Gateway, or the strategy process is no longer connected.
What Security Measures Should Protect Your IBKR VPS?
Protect the IBKR VPS with two-factor authentication, strong Remote Desktop credentials, Network Level Authentication, restricted firewall rules, and local-only API access where possible. The server contains trading credentials, strategy code, account data, and order permissions.
The TWS API socket should not be exposed to untrusted networks. When the strategy runs on the same VPS, restrict the connection to 127.0.0.1 and permit only the required local port.
| Security control | Required action | Risk reduced |
| IBKR Secure Login System | Keep two-factor authentication active | Unauthorized account login |
| RDP password | Use a long, unique credential | Password guessing and reuse |
| Network Level Authentication | Require NLA before session creation | Unauthenticated RDP access |
| Windows Firewall | Permit only required traffic | Unnecessary network exposure |
| TWS trusted IPs | Restrict API clients | Unauthorized socket connections |
| Read-Only API | Keep enabled until order access is needed | Accidental API trading |
| Windows updates | Schedule security patches | Known vulnerabilities |
| Strategy credentials | Store in a protected secret store | Plaintext credential exposure |
| User permissions | Remove unused administrators | Excessive access |
| Backups | Encrypt configuration and code copies | Data loss and disclosure |
IBKR’s Secure Login System uses a second authentication factor through IBKR Mobile, an authenticator application, or an approved physical device. A username and password alone are insufficient after the security system is activated. (Source: IBKR Secure Login System, 2026).
Microsoft states that Network Level Authentication adds an extra security layer by authenticating the user before a full Remote Desktop session is created. (Source: Microsoft Remote Desktop Access, 2026).
The trade server security guide covers firewall configuration, access control, patching, and monitoring for remote trading environments.
When Is a Home Computer Enough for Interactive Brokers?
A home computer is enough when you trade manually, remain available to monitor TWS, and do not need an API process to run unattended. The local setup must tolerate power interruptions, router failures, Windows restarts, and competing personal applications.
A VPS is not automatically necessary because an account holds positions overnight. Orders already accepted by IBKR can remain active without the desktop application, although locally calculated strategy actions cannot run while TWS or IB Gateway is offline.
| Home-based use | Why it can work | Main limitation |
| Manual order entry | The trader remains present | A local outage interrupts access |
| Portfolio monitoring | Continuous automation is unnecessary | Alerts may stop with the application |
| Occasional charting | The platform can be reopened as needed | Data may need to reload |
| Paper trading | No live capital is exposed | Infrastructure reliability is not proven |
| Strategy development | Restarts can be handled manually | Testing can interfere with live applications |
| One short market session | Required uptime is limited | Longer sessions increase outage exposure |
A home computer becomes insufficient when a required process must act while the trader is asleep, travelling, or disconnected. The decision should be based on the consequences of the local application going offline.
How Should You Test the VPS Before Running Live Strategies?
Test the Interactive Brokers VPS with a paper account and the complete production software stack before enabling live API orders. The test must include normal execution, IBKR disconnections, application restarts, Remote Desktop disconnection, and state reconciliation.
A successful API connection only proves that the strategy can open a socket. It does not prove that the strategy handles partial fills, rejected orders, pacing limits, or maintenance resets correctly.
| Test | Action | Passing result |
| API connection | Connect to paper TWS or IB Gateway | Correct client ID and port are accepted |
| Market data | Request approved instruments | Subscriptions update without pacing errors |
| Market order | Submit a small paper order | Correct account and quantity are used |
| Limit order | Submit and modify a paper order | Status changes remain synchronised |
| Cancel request | Cancel a working order | Broker and strategy states match |
| Partial fill | Simulate or observe a partial execution | Remaining quantity is handled correctly |
| Code 1101 recovery | Reconnect after data loss | Market data requests are resubmitted |
| Duplicate prevention | Replay an order instruction | No unintended second order is created |
| TWS restart | Trigger a controlled restart | Strategy reconnects and reconciles state |
| RDP disconnection | Close the remote window | Applications continue running |
| VPS restart | Reboot during testing | Startup procedure restores the stack |
| Authentication failure | Leave the weekly session unauthenticated | Monitoring produces an alert |
IBKR paper accounts support most TWS order types and instruments, making them suitable for testing platform behaviour before live deployment. Paper fills and market behaviour can still differ from live execution. (Source: IBKR Paper Trading Accounts, 2026).
Record the order ID, client ID, account, symbol, quantity, submission time, acknowledgement, and final state. Logs should make one API event traceable from the strategy through TWS or IB Gateway.
Interactive Brokers VPS Hosting: TWS Uptime, API Stability, and Performance
Interactive Brokers VPS hosting should provide sufficient resources for TWS or IB Gateway, stable connectivity to the assigned IBKR server, and a tested process for daily restarts and weekly authentication. A VPS improves the local infrastructure without removing IBKR’s scheduled maintenance requirements.
A 99.99% uptime service-level agreement permits approximately 52.56 minutes of potential infrastructure downtime per year. A 99.9% SLA permits about 8.76 hours.
| Requirement | Practical target | Why it matters |
| Uptime | 99.99% SLA | Reduces host-side interruptions |
| Processor | At least 2 fast vCPU cores | Supports TWS, Gateway, and strategy logic |
| Memory | 8 GB for a moderate TWS setup | Matches IBKR’s current minimum |
| Heavy-workload memory | 16 GB or more | Supports charts, data, and several applications |
| Storage | SSD or NVMe | Improves logs, startup, and application access |
| Location | Near the assigned IBKR server | Reduces avoidable network distance |
| Remote access | RDP with NLA | Supports secure administration |
| API security | Localhost or restricted trusted IPs | Protects the socket connection |
| Monitoring | Process and connection alerts | Detects restart or authentication failures |
| Recovery | State reconciliation after reconnect | Reduces duplicate or missed actions |
| Resource allocation | Guaranteed CPU and RAM | Reduces shared-host performance changes |
TradingFXVPS uses Microsoft Hyper-V with guaranteed resource allocation and a no-overselling policy. Available locations include New York, London, Frankfurt, Amsterdam, Chicago, Singapore, Tokyo, and Hong Kong.
The correct Interactive Brokers VPS should be selected from actual CPU, memory, and network measurements. Server capacity cannot correct invalid strategy logic, missing market data permissions, or incorrect API settings.
Keep Your IBKR Trading Setup Connected Beyond Your Home Computer
Build the VPS around the complete IBKR workflow: TWS or IB Gateway, strategy runtime, market data requests, restart settings, authentication, logs, and recovery controls. Test the setup on a paper account and confirm that it can restore its state after both an IBKR reset and a Windows restart.
TradingFXVPS can provide a remote Windows environment with a 99.99% uptime SLA, guaranteed Hyper-V resources, and locations near major financial infrastructure. The appropriate plan and location depend on the assigned IBKR server, TWS or IB Gateway choice, API workload, and number of additional trading applications.

Frequently Asked Questions About Interactive Brokers VPS Hosting
Can Trader Workstation run continuously on a VPS?
Yes, TWS can remain open on a VPS between Remote Desktop sessions. It still encounters IBKR’s scheduled connection resets and must complete its daily restart process.
Manual weekly authentication remains required. Monitoring should detect when TWS does not return to an authenticated state.
Is IB Gateway better than TWS for automated trading?
IB Gateway is usually better for a dedicated API server because it uses fewer resources. IBKR states that it consumes about 40% fewer resources than TWS.
TWS is better when you need charts, BookTrader, Risk Navigator, or visual order management. Both applications provide the same type of TWS API socket connection.
How much RAM does an Interactive Brokers VPS need?
A moderate TWS VPS should have at least 8 GB of RAM. IBKR currently recommends 16 GB for stronger TWS performance.
A lightweight IB Gateway setup can use less, but the strategy runtime and other applications also need memory. Monitor the full production workload before reducing resources.
Will closing Remote Desktop stop an IBKR API strategy?
No, disconnecting Remote Desktop normally leaves TWS, IB Gateway, and the strategy running. Signing out of Windows or shutting down the VPS closes the applications.
Use Disconnect instead of Sign out. Confirm that no session timeout policy is configured to log off disconnected users.
Does a VPS prevent every TWS or IB Gateway disconnection?
No, a VPS cannot prevent every disconnection. IBKR performs scheduled maintenance and requires regular application restarts and authentication.
The VPS mainly removes failures caused by the home computer, router, power supply, and residential internet. The strategy must still process IBKR connection codes correctly.
Can one VPS run IBKR alongside other trading platforms?
Yes, one VPS can run IBKR with other trading platforms when it has enough CPU, RAM, storage, and network capacity. Each added terminal or application increases the combined workload.
Use separate logs and startup controls for each application. Upgrade or separate workloads when one platform begins delaying another.
