I need a seasoned IBKR API developer who can jump straight into Python and deliver a production-ready toolkit that does three things right out of the gate: fetch real-time and historical market data, place and manage a variety of orders, and expose the full range of account information (balances, positions, margin, activity). The workflow I have in mind is simple: I start Trader Workstation or IB Gateway, run your Python package, and interact with well-documented functions that wrap the official ibapi (ib_insync is fine if you prefer). Calls should be non-blocking, handle reconnects, and surface clear exceptions so I can slot the code into a larger trading system without surprises. Deliverables • Clean, modular Python code (PEP-8 compliant) • Quick-start script that demonstrates data fetch, order submission, and account snapshot • README covering setup, dependencies, and example calls • Brief hand-off session to walk through the code Acceptance will be based on: 1. Scripts running end-to-end against a live paper account with no manual tweaks. 2. Latency and error handling consistent with IBKR guidelines. 3. Clear separation between configuration (e.g., credentials, contracts) and core logic. I’m ready to test as soon as you are, so please factor an immediate start into your timeline.
