Separating 0DTE from the rest of the day’s option volume
Recorded in cvforge on July 24, 2026 by ConvexValue · Published July 25, 2026
The day’s most actively traded contracts, split into same-day expirations and everything else — because mixing the two makes a volume ranking almost meaningless.
Exact prompt
Give me a dashboard analysis of today's most actively traded options - separate between 0dte and others.
Data cadence
Live U.S. option snapshots, refreshed through the session. Open interest is an end-of-previous-day figure and updates once daily.
Plan requirements
Runs on the free cvforge app and the free data tier (20 requests/hour). No card needed.
Fields used
day_volume, open_interest, strike_price, expiration_date, contract_type, underlying_price, fair_market_value
How to read it
Any “most active options” list is dominated by same-day expirations, which are a different instrument in practice: they are opened and closed within hours and never appear in tomorrow’s open interest. Ranking them alongside a six-month contract tells you almost nothing.
The split is the whole point. Read the two panels separately — the 0DTE side describes what happened during today’s session, the non-0DTE side describes positions that will still exist tomorrow. Only the second one has any carry-over meaning.
Change it
The prompt is the interface. Ask for a different ticker, a different expiration window, or an extra column in the same sentence style and the agent edits the app in place — you do not start over, and you do not wait for anyone to build it.
Limitations
- Snapshot data, not a transaction tape: the build reads the chain as it stands, so it cannot attribute a trade to a buyer or a seller.
- Open interest updates once a day, so an intraday volume/OI comparison is always this session’s volume against yesterday’s open interest.
- Contract coverage is U.S. listed equities, ETFs and indices. Indices use the I: prefix, for example I:SPX.
- Current per-contract valuation is Massive fair market value (FMV), a proprietary estimate. cvforge does not provide option bids, asks, midpoint, quote sizes, NBBO or last trades, and FMV is not an executable quote.
- Same-day contracts expire within hours, so a snapshot taken minutes later can look materially different.
- On expiration day open interest is stale by construction: the positions it counts are the ones that survived to this morning.
