A practitioner’s guide to SPX 0DTE options strategy, GEX mechanics, and the AI-augmented framework that runs them.
A book by a practitioner for practitioners. Twenty-five years in technology, several in 0DTE structural trading, and a framework built session by session in paper mode before a dollar of live capital touched it. The book documents the framework end-to-end — the GEX-derived structural map, the rules that fire at entry and at exit, the six prompts that run the workflow, and the journal that records every session against the rules that should have governed it.
The framework is AI-augmented. AI does the work AI does well — reading dense premarket structure, running checklists at speed, running post-mortems against fixed criteria — so the trader can do the work the trader does well: reading the tape, exercising discipline, deciding whether a session aligns with the rules that govern entries. The book is the practitioner manual for that division of labor.

For the experienced practitioner of the framework
Clarifications and refinements to the framework as it matures in practice, organized by the part of the book they touch.
William M. Wass is a technology practitioner with twenty-five years of IT consulting experience. The trading framework documented in this book grew out of a question that surfaces naturally for someone who has spent a career building, hardening, and auditing complex systems: what would it take to run a trading discipline the same way?
