The U.S. Options Global Trading Hours (GTH) Trade-Only dataset provides tick-level trade data during Cboe Global Trading Hours, covering extended overnight trading sessions outside regular U.S. market hours. The dataset spans 20:00:00 to 09:25:00 Eastern Time, from Sunday evening through Friday morning, and captures executed trades for S&P 500® Index (SPX) options, Cboe Volatility Index® (VIX) options, Mini-SPX Index (XSP) options, and Russell 2000® Index (RUT) options traded on Cboe during GTH. Each trade record includes the corresponding National Best Bid and Offer (NBBO) at the time of execution, enabling accurate contextual analysis of price formation and execution quality during extended hours. The dataset is trade-focused, providing a clear view of overnight options activity while preserving essential quote context at execution time.
