I need a Python-based wrapper that talks directly to Webull so I can place and manage trades programmatically. The core functions must cover market buy/sell, stop-loss and limit orders, plus a way to pull order status in real time and cancel or amend an order when needed. Security is non-negotiable: keep all traffic encrypted, store my tokens or credentials only in an encrypted form, and create an activity log that records every request, response, and order update for later audit. The log should never expose raw credentials. Please structure the work as a small, reusable library or micro-service, with clean functions (or REST endpoints if you prefer) for: • placing an order (market, limit, stop-loss) • checking, modifying, or cancelling an existing order • retrieving balances and positions Deliverables are straightforward: 1. Well-documented Python code (PEP-8 compliant) 2. A short setup guide and usage examples—ideally a Jupyter notebook or simple CLI demo 3. Unit tests that prove each order type works against Webull’s paper-trading or sandbox environment 4. A brief note describing how you implemented encryption and activity logging If you have previous experience with brokerage APIs or Webull specifically, let me know; otherwise, be ready to show that you can navigate their authentication flow and rate limits quickly.
