Historical Stock Data: 19 Sources of US Price History, Ranked

Historical stock data is not one product. Some providers sell raw, tick-by-tick trades; others sell a single adjusted daily bar, smoothed for splits and dividends before you ever see it. We ranked 19 sources of historical stock data on depth and cost, and on whether it adjusts prices and how much options history it keeps, then priced what 10 years of it actually costs at each.

We sell candles back to 2010, split-adjusted by default, with a raw format available on request. That default caused our one verified pricing dispute of 2026, below, and it’s the reason we rank second rather than first.

How did we rank the sources of historical stock data?

Each provider was scored from 0 to 10 on six criteria: how far back its history reaches and whether it includes intraday bars; its price and whether it offers unadjusted prices as a choice; bulk delivery and options history depth. Every criterion counts once, except intraday and options history, which count one and a half.

EODHD ranks first here on 40 years of history for $16.58 a month; we rank second.

Which historical stock data provider ranks best?

The six highest-ranked sources, side by side:

EODHD

EODHD reaches 40-plus years of US history, adjusted and delisted tickers included, for $16.58 a month billed annually. Its options history only reaches back to the fourth quarter of 2023, about two and a half years.

Market Data

Our candles run back to 2010, unlimited depth on the Trader plan at $30 a month billed annually, split-adjusted by default with the unadjusted series available on request. We have no bulk or flat-file delivery, and our options history is unadjusted with no historical greeks.

Nasdaq Data Link

Nasdaq Data Link’s Sharadar tables price US equities back to January 1998, adjusted or unadjusted, your choice, for $16.58 a month billed annually. Its options coverage is fragmented, single-exchange EOD data with no consolidated OPRA chain.

Tiingo

Tiingo includes 30-plus years of US history and one-minute bars since 2017 on its free, $0-a-month Starter tier. It sells no options product at any price.

Finnhub

Finnhub’s bulk one-minute and trade downloads reach back to 1994, deeper than most on this list, but it has zero options endpoints in its own published schema.

Databento

Databento’s tick history is nanosecond-timestamped, but its named US-equities dataset itself only reaches back to 2018, so it’s the one provider here that doesn’t clear the 10-year bar at any price.

What does 10 years of historical stock data cost, with options history too?

Comparable access, the full plan a 10-year daily history needs:

EODHD and Nasdaq Data Link both land near $16.58 a month billed annually; ours is $30. Five or more years of end-of-day options chains on top of that costs:

Our Starter plan, $12 a month billed annually, already includes five years of options history out of data that itself runs back to 2010.

Why did our historical stock prices not match another provider’s numbers?

Our biggest verified pricing dispute of 2026 involved an institution’s software team valuing donated stock for tax purposes under IRS Publication 561. Their engineer reported our candles didn’t match other quoting services on specific dates, and a re-query of the same historical date weeks later returned different numbers than the first query had.

With our agreement, the customer withheld a subscription payment for five weeks, from mid-April to May 20, 2026, until the dispute closed.

The fix was two query parameters: adding adjustsplits=false&adjustdividends=false to the request made all five reported discrepancies disappear, because a value already adjusted for a split or dividend is not the price that traded on that date, and it changes again whenever a new corporate action occurs. We also found and disclosed a separate, real defect: a small number of OHLC values were losing their third significant decimal, filed and tracked internally as api#106.

How do we adjust historical stock prices for splits and dividends?

An adjusted price is rewritten so a chart looks continuous across a split or spin-off. We adjust daily candles for splits and corporate actions by default and never for dividends, and the as-traded, unadjusted series sits on the same endpoint, one parameter away.

When should you not use Market Data for historical stock prices?

Use another provider if you need bulk flat-file delivery or historical greeks for an options backtest. Nasdaq Data Link and EODHD sell the first; ThetaData sells the second, and we sell neither.

Our own historical stock data API documents the adjustment parameters named above, and the overall ranking of financial data providers compares all 19 sources on more than history. For options history specifically, our options data providers ranking goes deeper. The IRS’s own Publication 561 sets the valuation rule the institutional case above was built on.
