Where the top 100 names’ call and put volume actually sits
Recorded in cvforge on June 12, 2026 by ConvexValue · Published July 25, 2026
Two pie charts splitting call and put volume across the hundred largest option markets, with a toggle to exclude indices and the biggest ETFs.
Exact prompt
Create 2 pie charts showing the volume of the top 100 by calls and puts. Give me a toggle to exclude indices and top ETFs.
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
How to read it
The toggle is the feature. Index and large-ETF options are so dominant that leaving them in makes every market-wide volume chart a chart about SPY — and excluding them reveals the distribution across single stocks, which is the question most people meant to ask.
Flip it both ways. With ETFs included you see how concentrated listed option trading really is; with them excluded you see which individual companies are drawing attention. Both are useful and they are almost entirely different pictures.
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.
- Concentration at a strike shows where contracts changed hands, which is not the same as where the underlying is expected to settle.
