I’m building a fully automated day-trading system on Interactive Brokers and need the core algorithm coded end-to-end. The logic already exists on paper: a series of entry filters, profit-target calculations and dynamic stop-loss rules that must all fire in real time through the IB API. I’m flexible on language—Python, Java, C++, or any other solution is fine as long as it is officially supported by Interactive Brokers and easy for me to maintain later. What I expect: • A clean, well-commented codebase that connects to TWS/Gateway, streams market data, evaluates multiple conditional signals, and submits, modifies, and cancels orders automatically. • Parameter files or an intuitive UI so I can tweak quantities, price offsets, time filters and risk caps without touching the source code. • Logging and basic error handling that captures every order event and API message for post-trade analysis. • Brief hand-off session (video or written) explaining deployment, config, and how to extend the strategy set. Acceptance criteria will be a live demonstration on a paper account showing at least one complete trade cycle—entry, target hit or stop-loss execution—triggered purely by the coded rules.
