How to read it
Ranking by premium rather than contract count is the decision that makes this useful. Ten thousand contracts at five cents and a hundred at fifty dollars have similar notional significance and very different contract counts, and premium is the measure that puts them on the same scale.
“Expiration pressure” is worth reading as a second dimension: activity concentrated into one expiration is a different situation from the same volume spread across the calendar. As always, this describes the chain, not the tape — no contract here is attributed to a buyer or a seller.
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.
