0DTE Options Research in Liquid ETFs

Studying SPY, QQQ, and DIA Options, Pricing Sensitivities, and Expiration Mechanics

0DTE options research in liquid ETFs, SPY, QQQ, and DIA options mechanics, pricing sensitivities, and expiration behavior - this book is a structured study of how same-day options can be observed and documented without hype or promises. It focuses on how implied volatility, skew, term structure, and quote quality can shift intraday, and how a careful notebook can turn those observations into comparable records.

Readers may learn about:

• The core mechanics of 0DTE ETF options, including time-to-expiration effects and settlement considerations

• Observing implied volatility as a surface: IV level, skew, and term structure in plain language

• Research-friendly ways to track quote quality (spreads, quote texture, prints vs mids) and confidence grading

• Mapping moneyness consistently across SPY, QQQ, and DIA to avoid apples-to-oranges comparisons

• Using “near-the-money zones” instead of single strikes to reduce reference drift

• Scenario buckets and context tags for grouping windows (open, midday, late) and comparing like-with-like

• Studying scheduled context and calendar concentration as labels for sorting observations, not explanations

• Building a monthly review process that summarizes observations without turning the notebook into a scorecard

Written in a calm, practical mentor voice, 0DTE Options Research in Liquid ETFs is designed for readers who want a clearer way to study same-day options behavior in major index ETFs. The emphasis stays on measurement discipline, cautious language, and repeatable comparison - so the reader can build a more reliable research record over time.
