I need a Python‐based trading bot that plugs directly into Broker's SDK and executes fully automated trades on the NSE. The core objective is a clean, well-documented workflow that: • Authenticates with Broker A’s API and maintains a stable session • Streams live NSE market data from the SDK • Generates, places, modifies, and cancels orders automatically based on my strategy hooks • Logs every request/response for audit and debugging Please build the solution in modular, well-commented Python 3.x so I can swap in new strategies later without touching the integration layer. A concise README with setup steps, environment variables, and example strategy templates will be the final acceptance test.
