Note: Replace placeholder values like "your_api_key" and "http://127.0.0.1:5000" with actual API keys and URLs as required by your setup. All functions assume the existence of a network communication setup within the MetaTrader 5 environment, as well as an OpenAlgo API that responds to the specified endpoints. Ensure proper error handling and API rate limiting as per the service provider's specifications.
