- Data Coverage Category
Data Coverage
- Indices Category
Indices
- Description
- No, and the ones it withholds are the famous ones: SPX, DJI, RUT and VIX all need a paid Indices tier. Basic still reaches more than 10,000 of the 13,000-odd indices Massive publishes, and NDX and the Nasdaq Composite are among them.

- Data Coverage Category
Data Coverage
- Options Category
Options
- Description
- Yes. Index option contracts carry the same Greeks, implied volatility and open interest as equity options. Query the chain from the options snapshot with the prefixed index, as I:SPX; the bare SPX returns the same contracts with no Greeks.

- Options Category
Options
- Description
- Yes. Index options are covered by the Options subscription, and every options endpoint accepts them. The snapshot endpoints need the prefixed index, as in I:SPX, to return Greeks, while the reference endpoints only accept the bare symbol, as in SPX.

Sources
- Stocks Category
Stocks
- Description
- From the two US securities information processors, the Consolidated Tape Association and the UTP plan, which consolidate every US exchange, plus the FINRA facilities that carry off-exchange prints. That is the whole tape, not a sample of venues.
- Title
- Do Massive's Futures plans include VIX futures, or exchanges like ICE and Eurex?
- Data Coverage Category
Data Coverage
- FAQ Category
FAQ
- Description
- Massive's Futures plans cover the four CME Group exchanges, CME, CBOT, NYMEX and COMEX, so VIX futures, which trade on the Cboe Futures Exchange, and contracts listed on ICE, Eurex or any other exchange are not available on any plan.
- Title
- Does ETF Global's NAV match the issuer's NAV, and when is it updated?
- Data Coverage Category
Data Coverage
- FAQ Category
FAQ
- Description
- The nav field in Massive's ETF Global Fund Flows data is the fund's NAV per share as its issuer publishes it, not adjusted afterward for splits; the dataset is updated daily, and its records carry dates but no time of day.
- Title
- Does Massive have a market holiday or status page?
- Data Coverage Category
Data Coverage
- Reference Data Category
Reference Data
- Description
- Yes, as two API endpoints rather than a web page. /v1/marketstatus/now returns whether each exchange is open, in pre-market or after-hours, and /v1/marketstatus/upcoming returns the coming holidays with their early-close times.
- Title
- Why is my snapshot missing the last trade, last quote or other fields on my plan?

Data Coverage
- Options Category
Options
- Stocks Category
Stocks
- Description
- Snapshot fields follow your plan: the last trade is returned only on plans that include trades, the last quote only on plans that include quotes and fair market value only on Business plans, and in the unified snapshot a ticker your plan does not cover comes back as a NOT_ENTITLED row.
- Title
- Does Massive have continuous futures contracts?
- Data Coverage Category
Data Coverage
- FAQ Category
FAQ
- Description
- No, each futures contract is its own ticker, so to follow a product over time you request one contract after another and switch when trading moves to the next one, which can happen days or weeks before the expiring contract's last trade date.
- Title
- Does Massive have data for any options that are traded after 4 PM ET?
- Data Coverage Category
Data Coverage
- Options Category
Options
- Description
- Yes for the sessions that run on from the 16:00 Eastern close: broad ETF options such as SPY and a set of single-stock options such as AAPL and NVDA trade until 16:15, Cboe index options such as SPX and VIX until 17:00, and Massive's trades feed carries those prints like any other.
- Title
- Does Massive have historical open interest for options?
- Data Coverage Category
Data Coverage
- Options Category
Options
- Description
- No, Massive returns options open interest only on its snapshots, as the latest daily figure for contracts that have not yet expired, so a history of past values has to be built by saving that figure once each trading day.

- Data Coverage Category
Data Coverage
- Options Category
Options
- Description
- Yes for single-stock and ETF options in the early session that began on 19 October 2026, such as AAPL, NVDA and SPY, whose trades, quotes and minute bars start at 07:30 Eastern; other options start at 09:30, and Cboe's overnight SPX and VIX session is not covered beyond some early-morning trades.

- Financials Category
Financials
- Reference Data Category
Reference Data
- Description
- Yes, every record on the financials endpoints carries a filing_date, but it is the date of the most recent SEC filing that included the period, which is often later than the date the period was first reported, so the original filing date comes from the SEC EDGAR Index endpoint.

Data Coverage
- Forex Category

- Business Category
Business
- Data Coverage Category
Data Coverage
- Description
- Redistribution needs a commercial license, not an individual subscription. Showing data to your own users, publishing it, or passing it to another party all count. Several commercial plans are self-serve on the business page; the rest go through sales.

- Massive documents each trading day's flat files as available by about 11:00 AM ET the following day; a file can be downloaded as soon as it appears in the bucket, which for stock files is often hours earlier, and splits and dividends are updated daily with no published time of day.

- Aggregates Category
Aggregates
- Data Coverage Category
Data Coverage
- Description
- REST stock bars are split-adjusted by default and the stock flat files never are, so request adjusted=false; every asset class also differs in format, such as timestamp units, ticker spelling or decimal places.
- Title
- Why is Massive's market data different from other providers?
- Data Coverage Category
Data Coverage
- FAQ Category
FAQ
- Sources Category
Sources
- Description
- Usually because of four things: which trades are eligible to update a bar, which timestamp the data is bucketed on, whether prices are split-adjusted, and whether late corrections have been applied. All four are checkable.
- Title
- Why is the stocks snapshot's day bar zero before the open, and how do I get the pre-market change?
- Data Coverage Category
Data Coverage
- Stocks Category
Stocks
- Description
- The stocks snapshot's day bar covers the regular session, so it reads zero from the 3:30 AM Eastern reset until the ticker trades after 9:30 AM, and before the open the pre-market change is in todaysChange and todaysChangePerc, which compare the last trade with the previous close.
