This listing is offered at no charge. It covers one month of 2020 US equity trade and quote minute bar data in CSV format, with off-exchange trades reported to FINRA Trade Reporting Facilities excluded. Pricing carries a single dimension with no tiers, quantity choices, or usage add-ons. You get the specified month of data under this free option, so there is no scaling logic or metered billing to weigh. Because only one dimension exists, there are no size, term, or volume variations to compare.
Top-of-mind questions for buyers
What data does one free month cover, and what does 'excluding TRF' mean?
You get one calendar month of 2020 US equity minute bar data in CSV. Each one-minute bar carries market microstructure metrics like spread and order-flow measures. 'Excluding TRF' means off-exchange trades reported to FINRA Trade Reporting Facilities are removed, leaving a view of exchange-only trading activity.
How is a minute bar built when no trades or quotes occur in that minute?
The dataset uses a continuous minute-bar timeline. When no trading or quote updates happen in a given minute, the most recent bid and ask values carry forward. This produces a gap-free time series across the month, which simplifies joins and downstream model building.
Are there any exchange fees or ongoing charges tied to this free historical dataset?
No. This listing is free and covers historical data only. Historical US equity data carries no exchange licensing fees, so the price is all-inclusive for the single month provided. There is no metered usage, no per-user charge, and no recurring billing on this option.
