A filterable board of today’s option-activity outliers
Recorded in cvforge on June 30, 2026 by ConvexValue · Published July 25, 2026
The same daily outlier view with controls added — delta, volume/OI ratio, and a mask for index and ETF contracts — so the list can be narrowed to what you trade.
Exact prompt
Give me a dashboard visualization of unusual options activity today. I want to be able to filter by delta, volume/oi ratio, and mask index/etf.
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, implied_volatility, delta
How to read it
The difference from the static version is entirely interaction, and it is the difference between looking at someone else’s list and using your own. Same data, same ranking, three controls.
The index/ETF mask is the control that changes the output most. Index and ETF contracts are so much larger than everything else that they occupy the top of any unfiltered ranking every single day, which makes the unfiltered version nearly useless for finding single-stock activity.
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.
- A high ratio says positions were opened, not which direction anyone expects. Read it as an attention signal, not a forecast.
