Cboe has launched two complementary datasets for complete visibility into options trading activity on the Cboe Options Exchange (C1).

• Cboe Open-Close is an options summary trade data file designed to help you analyze participant positioning, market sentiment and trading dynamics. One-minute interval data provides near real-time monitoring of intraday positioning shifts and sentiment fluctuations.
• Trade-by-Trade data delivers complete, execution-level visibility into C1 options trading. Instead of aggregates and summaries, like Cboe Open-Close, Trade-by-Trade captures every executed trade with full market context, enabling you to understand how, why and where liquidity truly forms.
