The U.S. Equities Trade and Quote Minute Bar dataset provides a minute-by-minute analytical view of U.S. equity market activity, derived from consolidated trade and quote (TAQ) data. Each one-minute bar contains approximately 60 calculated metrics, summarizing intraday price behavior, quote dynamics, and trading activity. In addition to standard Open, High, Low, Close, and Volume (OHLCV) measures, the dataset includes market microstructure indicators such as trade classification at bid/mid/ask, uptick and downtick statistics, bid-ask spread measures, and time-weighted bid and ask metrics. These features support intraday liquidity analysis, signal development, and short-horizon market studies without the complexity of tick-level data. The dataset uses a continuous minute-bar timeline. When no qualifying trade or quote updates occur during a given minute, the most recent bid and ask values are carried forward, ensuring a complete, gap-free time series that simplifies downstream joins and modeling. 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 U.S. public-traded equity issue types, including common and preferred stocks, ETFs, ETNs, ADRs, warrants, and units.
