Zero DTE Options for Beginners

A Beginner’s Guide to Same-Day Expiration Options

Zero DTE Options for Beginners is a clear, calm introduction to options contracts that expire on the same trading day. Written for readers new to same-day expiration, this book focuses on understanding structure, mechanics, and risk rather than outcomes or instructions.

Zero days to expiration options, often called Zero DTE or 0DTE, behave differently from longer-dated options. Time is compressed, sensitivity can change quickly, and prices often respond in ways that feel unfamiliar to new readers. This guide explains why those differences exist and how the market expresses them as expiration approaches.

Instead of presenting strategies or promises, the book takes an educational approach. It explains how time, volatility, market structure, and option sensitivity interact inside a single trading session. Complex ideas are introduced gradually and explained in plain English, with fictional examples used to illustrate common patterns without implying results.

Topics explored include:

• What Zero DTE options are and how same-day expiration works

• How time pressure changes option behavior

• The role of volatility and priced uncertainty

• Why sensitivity can appear nonlinear near expiration

• How liquidity, spreads, and market structure shape what prices look like

• Common misunderstandings about risk in short-duration options

• Descriptive frameworks used to interpret intraday option behavior

This book is designed for beginners who want context before complexity. It does not teach how to trade or what actions to take. Instead, it provides language, structure, and perspective for understanding how Zero DTE options function as contracts nearing expiration.

All examples are fictional and illustrative. The material is presented for educational purposes only, with an emphasis on scope, limits, and careful interpretation.

Zero DTE Options for Beginners is suitable for readers who are curious about same-day expiration options and want a structured, non-promotional introduction to how these instruments behave within modern markets.
