A fully automated, AI-developed trading system for S&P 500 same-day-expiration options — built, owned, and operated by its founder.
Chelsea Addison Capital is a single-strategy firm. We research, build, and operate one thing: a systematic trading program in SPX zero-days-to-expiration options, where every decision — entry, exit, sizing, and risk — is made by tested rules and executed by machine.
There is no discretionary trading. Every entry, every exit, and every risk decision is rule-driven — researched in-house, tested against history, and executed automatically.
An AI-developed entry framework that responds to evolving option-chain structure and intraday price expansion, validated on a custom-built backtesting engine with strict over-optimization controls.
The system monitors the market at high frequency throughout the session, with automated position-level stops, dynamic exposure, and automatic de-risking when conditions change.
