US Equities Trade and Quote

GET https://api.devalgoseek.com/api/v1/data/us-equity/eq-taq/:trade_date/:ticker#

The U.S. Equities Trade and Quote (TAQ) dataset provides a complete, tick-level record of executed trades and level 1 bid/ask quotes for U.S. exchange-listed equity securities, as well as NBBO indicators, delivering a consolidated view of market activity across the U.S. equities ecosystem. The dataset is derived from the U.S. Securities Information Processor (SIP), also known as the Consolidated Feed, and includes data from Tape A and Tape B (CTA Plan) and Tape C (UTP Plan). It captures all trades and top-of-book quotes from all SIP participant exchanges and trading venues, covering common stocks, ETFs, ETNs, ADRs, and related equity instruments. Each trade and quote event is timestamped at nanosecond resolution and includes exchange identifiers, condition codes, and National Best Bid and Offer (NBBO) context, enabling precise reconstruction of market state and execution conditions. The dataset reflects raw consolidated feed data as disseminated, without post-processing or normalization, preserving historical market conditions for accurate replay, research, and analysis.

For more details, please refer to the dataset documentation: US Equities Trade and Quote Guide.
