Ranking underlyings by put volume, absolute and relative
Recorded in cvforge on June 9, 2026 by ConvexValue · Published July 25, 2026
Two rankings side by side: the largest put volume in contracts, and the highest put-to-call ratio — which almost never surface the same names.
Exact prompt
Show me a ranking of underlyings based on put volume. I want to see both absolute put volume and the ratio of put volume to call volume
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, implied_volatility, delta, strike_price, expiration_date, fair_market_value
How to read it
Asking for both measures in one prompt exposes something a single ranking hides. Absolute put volume is a liquidity ranking: it returns the index ETFs and the largest names, every day, almost regardless of sentiment. The ratio ranking returns smaller names where something specific is happening.
Read them as two different questions. The first tells you where puts trade; the second tells you where puts are unusually preferred over calls. Only the second one changes much day to day.
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.
- Screens rank what is in the snapshot at the moment they run. Re-running later in the session gives a different shortlist.
