The explosion of zero-days-to-expiration options has fundamentally rewired market microstructure, creating unparalleled opportunities alongside explosive intraday risk. This book is written specifically for options traders, quantitative analysts, and risk managers navigating the extreme velocity of same-day expiries. Moving beyond superficial guides, it offers a rigorous framework for surviving a landscape dominated by rapid time decay, volatility jumps, and algorithmic dealer flows.
At its core, the text deeply explores the unforgiving gamma-theta trade-off and the near-expiry asymptotic behavior of the Greeks. Readers will master the structural mechanics separating cash-settled SPX options from the complex assignment realities of single-stock 0DTEs. The curriculum systematically details directional and premium-harvesting strategies, bound by robust intraday risk controls. By deconstructing gap risk and discrete hedging slippage, practitioners will learn to execute architectures that withstand fast-market conditions without suffering catastrophic tail losses.
Differentiating itself through high-fidelity backtesting protocols and execution modeling, this guide bridges theoretical quantitative research with live trading playbooks. Assuming a baseline knowledge of options pricing, it focuses precisely on the microscopic timeframes where traditional diffusion models fail. Readers will walk away with the operational guardrails, dynamic hedging techniques, and algorithmic limits required to manage severe convexity and institutionalize their short-horizon trading operations.
