I need a purpose-built bot that can execute fully automated buying and selling of stocks throughout the trading day. The core objective is to run a strict day-trading strategy: open positions after the bell based on real-time signals, close everything before market close, and do so without manual intervention. The bot should: • Connect reliably to my preferred broker’s stock-trading API (Interactive Brokers or a similarly robust gateway). • Ingest live price and volume feeds, evaluate my pre-defined entry/exit rules every few seconds, and place market or limit orders instantly. • Enforce risk controls such as max position size, daily loss cap, and hard stop-loss per trade. • Log every decision (signal, order details, fills, P&L) to a local database for easy review. • Offer a simple dashboard or CLI where I can toggle the strategy on/off and adjust key parameters (risk, symbol list, time window). Acceptance criteria – Bot compiles and runs on Windows or Linux with clear setup instructions. – Simulated back-tests on one month of intraday data match expected win/loss ratios. – Live paper-trading session completes a full market day with zero manual fixes required. – Source code is clean, modular, and documented well enough for me to tweak indicators later. Preferred tech: Python with libraries such as pandas, NumPy, ta-lib, and websocket support, but I’m open to C# or Node.js if you already have a proven framework. If you’ve built stock trading automation before—especially day-trading systems—let’s talk. I’m ready to start as soon as you can demonstrate an initial proof of concept.
