Fruit Stand publishes the Historical Stock Prices listing. Details for the
other listings come from their Marketplace pages and documentation as of
November 2, 2026, and the figures on Curated Data come from our own queries
of its free tier. For a full side-by-side of every listing, see

Why people look for an alternative
Snowflake Curated Data (formerly Cybersyn) gets its stock prices from Nasdaq TotalView through Databento. Its documentation says the prices cover all trading sessions: the open is the pre-market open, the close is the after-hours close, and volume counts trades on Nasdaq only. That’s a valid design for studying full-day trading, but it causes four problems for most other uses:- The close isn’t the official close. Across 4,289 exchange-listed stocks over $5 in July 2026, Curated Data’s close differed from the official close by more than 1% on 11.2% of stock-days, and by more than 5% for 396 stocks on at least one day. Even Snowflake’s own sample query for year-to-date performance uses the after-hours close.
- Volume and days are Nasdaq-only. Nasdaq volume was 7–33% of total volume for the stocks we checked, and 19% of exchange-listed ETF trading days from May to July had no row at all.
- The free tier is three months behind. On November 2, its latest prices are from July 31. The paid tier has no lag but costs $25,000 a year.
- Coverage stops at Nasdaq-traded stocks and ETFs since 2018. There are no OTC stocks, no mutual funds and nothing before May 1, 2018.
The alternatives at a glance
Historical Stock Prices (Fruit Stand)
The closest replacement for Curated Data’s stock prices if you need the standard definitions. It has one row per security per day with the official open, high, low and close, consolidated volume across all US venues, and adjusted open, high, low and close restated when splits and dividends post. Its closes matched Nasdaq’s official closing price to the cent on every date we checked. It also covers what Curated Data leaves out: complete history back to each security’s listing date (50+ years for the oldest), OTC stocks and about 25,800 mutual funds. It refreshes daily by 5:00 AM PT and costs $100 a month after a 30-day free trial, against $25,000 a year for Curated Data’s paid tier. The limit to know: it doesn’t include delisted securities, so long backtests have survivorship bias. If that matters, use CRSP.CRSP US Stock Database
The standard for academic research and long backtests. It goes back to December 1925 and covers 32,000+ active and inactive securities on NYSE, NYSE American, Nasdaq, NYSE Arca and Cboe BZX, with delisting returns, corporate actions and returns with and without dividends. It’s updated monthly and licensed by request; CRSP is now part of Morningstar, which also lists it on the Marketplace. It’s the right choice when delisted stocks matter more than daily freshness.EDI and Bloomberg
For prices outside the US, Exchange Data International (EDI) publishes end-of-day prices from 170 exchanges since 2007, within 15 minutes of each market’s close, priced by usage. Its prices aren’t adjusted; adjustment factors are a separate EDI listing. A free sample listing has 2019 US data to test with. Bloomberg’s Equity Reference and Pricing Data covers 200+ exchanges, with a record per local exchange plus a composite record and Bloomberg’s reference data. Both are by request, so expect a sales process.Bright Data Finance Information
Free and instant, with roughly the last six months of prices scraped from finance web pages, including open, close, volume and the day’s range as text. It’s useful for a quick look at recent prices, not for history, returns or anything that has to be reconciled.FactSet Tick History
If you need intraday data rather than daily prices, FactSet publishes Level 1 tick history and minute bars on the Marketplace, with free sample listings. Snowflake’s own time-series analytics guide is built on it, including closing prices derived from the ticks. For daily end-of-day work it’s more data than you need.Outside the Marketplace
Market data APIs such as Polygon.io, Alpha Vantage, Intrinio and Quodd are the other common route. They sell end-of-day and intraday prices by subscription, and some, such as Intrinio, offer delivery into Snowflake. With most of them, though, you load the data yourself and keep it current, including restating adjusted prices whenever a split or dividend posts. How to Get Historical Stock Prices into Snowflake compares that work with using a Marketplace listing.When to stay with Curated Data
Curated Data is still the right choice if you’re studying after-hours trading itself, such as how stocks move between an earnings release and the next open, or if you already use its other datasets and want everything keyed to the same company IDs. Its documentation also says regular-hours prices and volume are planned, which would remove the biggest reason to switch. Check its data dictionary for a regular-session close before deciding.Switching from Curated Data
Moving from Curated Data to Historical Stock Prices is a query change. Eachvariable_name maps to a column (Post-Market Close to close, Nasdaq Volume to volume), and the long format becomes one row per security per
day:

Why don't Curated Data's prices match Yahoo Finance?
Why don't Curated Data's prices match Yahoo Finance?
Its close is the after-hours close and its volume counts only Nasdaq trades. Yahoo Finance, brokers and index providers use the official 4 PM close and volume from all venues. Snowflake’s documentation says this is because Nasdaq TotalView reports all trading sessions, while most sources use the regular-session SIP feed.
