Multiple TWS Instances

If you have accounts that require separate TWS logins (e.g., different usernames), you’ll need to run multiple TWS instances on different ports.

When to Use This

This applies when:

• You have accounts under different IBKR logins
• Each login requires its own TWS Desktop instance
• You want to consolidate monitoring in one OptionsRealTime setup

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:

1. Go to File → Global Configuration → API → Settings
2. Set the Socket Port to 7496, 7497, 7498, etc.
3. Click OK

See TWS Configuration for detailed setup with screenshots.

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

• Different ports for different TWS instances
• Client IDs restart at 1 for each TWS instance
• Same Host — All TWS instances run on localhost

Step 3: Test, Save and Start

1. Ensure all TWS instances are running and logged in
2. Test each account connection in Rover
3. Go to File → Save to save your configuration
4. Click Start Publishers to begin streaming

Step 4: Launch OptionsRealTime

1. Double-click OptionsRealTime from the desktop folder
2. The Select Account dialog shows all accounts from all TWS instances
3. Choose the account you want to view
4. Click OK

Multiple Windows, Multiple Monitors

OptionsRealTime allows you to open as many user interfaces as you want to any account. Launch multiple instances to view different accounts side by side — or different views of the same account across multiple monitors.
