A sortable put/call volume table across underlyings

Recorded in cvforge on June 12, 2026 by ConvexValue · Published July 25, 2026

Ticker, spot, total option volume, call and put volume and the put/call ratio in one sortable table, defaulting to the heaviest call volume.

Exact prompt

Give me a table displaying: ticker underlying price options volume call volume put volume put/call ratio

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.

What the agent built

  • to be able to sort by each column
  • default sorting to be call volume
  • filter by call, put, total volume
  • select number of rows on table (default 50)

Fields used

day_volume, open_interest, implied_volatility, delta, strike_price, expiration_date, fair_market_value

How to read it

Sometimes the right build is a table. The prompt specifies the columns, the default sort and the row count, and that specificity is the reason the output is immediately usable rather than a generic grid you then have to configure.

The put/call ratio column is the one to read across rather than down: a ratio near 1 is unremarkable almost everywhere, so what stands out is a name whose ratio is far from the rest of the table on a day when its volume is also elevated.

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.
