See what is recorded on Coverage, the columns in the data dictionary, and estimate any download on Downloads before you buy.
The size of each daily file you download. A file counts once per calendar month (UTC), so re-running a script or fetching the same file again is free. Browsing, coverage, estimates and samples never count.
Create a free account, no card needed. Every account can download every dataset, including full-depth order books, for our free sample days: the 1st of every month from November 2026 on every venue, plus October 13, 2026 for Kalshi (the other venues were recorded from October 15). Free sample files of each dataset are also linked from the data dictionary, no account needed.
Email us within 7 days of your first payment and we refund it in full, as long as you downloaded less than 5 GB. Cancel any time from your account; you keep your plan until the end of the period you paid for. Full details are in the cancellation and refund policy.
Our first 100 subscribers pay half price on Research or Full book for their first 12 months, monthly or yearly. After that the subscription renews at the regular price.
Recording started on October 12, 2026, and the archive grows every day. Each day is published the next morning, and the Data coverage page shows how much of each day was recorded.
Parquet, one file per dataset and UTC day, split by series or market for the large datasets. Every day has a manifest with row counts, sizes and SHA-256 checksums, and every dataset has a free sample.
Every row carries when our recorder received it and the venue's own timestamp, both in nanoseconds UTC. The Data coverage page shows how much of every day was recorded and lists every gap.
Explorer is for personal research. Research and Full book cover internal research at one firm, including trading on your own results. Redistributing the data or building it into a product needs the Institutional license.
Yes. Verify a university email (.edu, .edu.xx or .ac.xx) and your account moves to Research for free.
