All data is provided in U.S. Eastern Time (i.e., EST/EDT depending on the time of year).

Free sources are excellent for quick look-ups, and we encourage you to try them first. The differences show up in serious research: our dataset includes over 50,000 delisted tickers with full frozen history (free sources generally drop delisted companies, which introduces survivorship bias), every row carries both unadjusted and split/dividend-adjusted prices side by side, minute data includes pre-market and after-hours sessions, and you download the complete market as one reproducible snapshot instead of fetching symbol by symbol through rate-limited APIs. The processing rules are documented on our methodology page.

Yes. More than 50,000 delisted U.S. tickers are included with their complete price history, frozen as of the delisting date. The delisting date is part of each file name, and histories of different companies that reused the same symbol are kept as separate files.

Both versions are in the same file: each row contains the unadjusted Open/High/Low/Close/Volume/VWAP and the fully split- and dividend-adjusted equivalents, plus the dividend amount and split ratio on the event dates. Details are in methodology §5.

Yes. Each stock has a regular-session minute file (09:30–16:00) and an extended minute file that includes pre-market (from 04:00 Eastern) and after-hours sessions. Daily files cover the regular session.

The stock dataset is rebuilt every Saturday (U.S. Eastern). The options dataset is updated every U.S. trading day, typically available by about 5:30 pm ET. See methodology §2.
