The U.S. Equities Trade and Quote Extended Minute Bar dataset provides a high-resolution, analytics-rich minute-by-minute view of U.S. equity market activity, derived from consolidated trade and quote (TAQ) data. Each one-minute bar contains approximately 90 calculated metrics, capturing detailed price behavior, quote dynamics, and order-flow characteristics. In addition to standard Open, High, Low, Close, and Volume (OHLCV) measures, the dataset includes a broad set of market microstructure indicators, such as trade classification at bid/mid/ask, uptick and downtick counts, bid-ask spread analytics, and time-weighted bid and ask measures. These features are designed to support intraday liquidity analysis, signal research, and fine-grained behavioral modeling. The dataset uses a continuous minute-bar timeline. When no trading or quote updates occur during a given minute, the most recent bid and ask values are carried forward, ensuring a complete and gap-free time series that simplifies downstream joins and model construction. Data is derived from Equity Securities Information Processor (SIP) feeds and includes all eligible trades and top-of-book quotes, including off-exchange trades reported to FINRA Trade Reporting Facilities (TRF). Coverage spans all major U.S. equity issue types, including common and preferred stocks, ETFs, ETNs, ADRs, warrants, and units.
