Multiple TWS Instances
If you have accounts that require separate TWS logins, you’ll need to run multiple TWS instances on different ports.
When to Use This
Section titled “When to Use This”This applies when:
- You have accounts under different IBKR logins
- Each login requires its own TWS Desktop instance
Step 1: Configure TWS Ports
Section titled “Step 1: Configure TWS Ports”Each TWS instance needs a unique port. Configure them in TWS:
| TWS Instance | Login | Port |
|---|---|---|
| TWS #1 | user1 | 7496 (default) |
| TWS #2 | user2 | 7497 |
| TWS #3 | user3 | 7498 |
In each TWS:
- Go to File > Global Configuration > API > Settings
- Set the Socket Port to 7496, 7497, 7498, etc.
- Click OK
See TWS Configuration for detailed setup with screenshots.
Step 2: Configure Rover
Section titled “Step 2: Configure Rover”Add each account with its corresponding port:
| Account ID | Host | Port | Client ID |
|---|---|---|---|
| U1234567 | localhost | 7496 | 1 |
| U2222222 | localhost | 7496 | 2 |
| U7654321 | localhost | 7497 | 1 |
| U9999999 | localhost | 7498 | 1 |
Key Points
Section titled “Key Points”- Different ports for different TWS instances
- Client IDs restart at 1 for each TWS instance
- All TWS instances run on localhost
Step 3: Test, Save and Start
Section titled “Step 3: Test, Save and Start”- Ensure all TWS instances are running and logged in
- Test each account connection in Rover
- Go to File > Save
- Click Start Account Analyzers
Step 4: Launch OptionsRealTime
Section titled “Step 4: Launch OptionsRealTime”Click either of the Web UI buttons on Rover, or open any browser on your network and type the address shown on the button. For example: http://MyMachineName.local:5000
All accounts from all TWS instances are available. Select one, several, or all. Charts, metrics, quotes, tables and reports update based on your selection.
