0DTE Options Risk Management Foundations for Beginners

Sizing, Exposure Mapping, Loss Containment, and Scenario Thinking in Intraday Options

0DTE options risk management can feel different when time is measured in minutes and hours instead of days. 0DTE Options Risk Management Foundations for Beginners examines intraday options through a practical, plain-English lens: what a position is exposed to, how that exposure can change quickly near expiration, and how “what could go wrong” thinking helps reduce confusion in fast markets.

This book stays focused on descriptions and market mechanics rather than predictions. It separates risk into clear lenses - premium as cost, notional exposure as relationship, and scenario loss as realistic day-stories. It also treats execution conditions as part of lived risk, recognizing that spreads, slippage, and shifting liquidity can matter as much as direction in a short horizon.

Readers may learn about:

• Sizing as exposure shaping rather than confidence signaling

• Exposure mapping near expiration, including delta, gamma, and time decay in beginner-friendly language

• Why option response can diverge from direction when uncertainty is repriced intraday

• Liquidity, bid-ask spreads, and slippage as practical risk variables

• Scenario thinking that turns common intraday patterns into clear narratives

• Fictional “what could go wrong” case studies designed to build interpretation skills

Written in a calm mentor voice, this book is an educational reference for beginners who want a clearer vocabulary for intraday options risk - with an emphasis on sizing, exposure mapping, loss containment, and scenario thinking in same-day expirations.
