The Trade-by-Trade (TBT) dataset delivers comprehensive transaction-level detail for options trading on the C1 exchange, providing unmatched visibility into every executed trade. Unlike summary-level products such as Open-Close, which aggregate volume by participant and position, TBT captures each individual trade event with full execution context, enabling firms to analyze market behavior at its most granular level.

This dataset includes precise timestamps, underlying and OSI details, trade price and size, buy/sell and open/close indicators, participant capacity, and trade type classifications, along with market context such as NBBO and local BBO at the time of execution. Execution IDs for simple and complex trades allow for accurate linkage and reconstruction of trading activity. Delivered on a T+1 schedule, TBT is designed for advanced analytics, compliance monitoring, and historical market reconstruction, powering insights into liquidity, price formation, and trade behavior with unparalleled depth.

*TBT data is currently available for C1 only, with C2, BZX, and EDGX planned for future release.
