0DTE Options Trading: A Behavioral Finance Perspective

Decision Stress, Overconfidence, Recency Bias, and Crowd Narratives in Fast Markets

0DTE options trading, behavioral finance, and decision-making under time pressure - this book studies what tends to happen inside the mind when markets move fast and expiration is close.

0DTE Options Trading: A Behavioral Finance Perspective explores common cognitive and emotional patterns that can appear in same-day expiration environments, where rapid feedback and a loud internal clock can reshape perception. Instead of framing markets as a contest to “beat,” this book treats the session as an observation lab for attention, interpretation, and stress.

Topics include:

• How time pressure can narrow attention and speed up conclusions

• Overconfidence as a fast-forming state, not a personality trait

• Loss sensitivity, reference points, and why break-even can feel magnetic

• Recency bias and the tendency to let the newest candle dominate the story

• Confirmation bias, selective screens, and comfort-driven evidence filtering

• Sunk cost and escalation when time spent starts to feel like ownership

• Social proof, FOMO, and how crowd narratives transmit urgency

• Stress physiology, working memory limits, and “tunnel thinking”

• Relief-seeking loops, compulsive checking, and the search for steadiness

• How these forces interlock as one system in 0DTE settings

All examples are fictional and presented for educational discussion only. The aim is to provide clear language for recognizing patterns that many people experience in fast markets - so the difference between information and emotion, evidence and comfort, can be easier to observe.
