Implementation Reference
- The handler function for the 'stop_live_algorithm' tool. It authenticates with QuantConnect, prepares a request with the project ID, and sends a POST request to the 'live/update/stop' API endpoint to stop the live algorithm. Handles various response cases including success, errors, and exceptions.
