Scanning for stocks with more call volume than put volume

Recorded in cvforge on May 16, 2026 by ConvexValue · Published July 25, 2026

A one-sentence scan across U.S. underlyings for names whose call volume beat put volume today, and the ratio that ranks them.

Exact prompt

I want to scan for the stocks that had a higher call volume than put volume today

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

A call/put volume split is the crudest possible read on positioning and it is still useful, provided you remember what it does not say. Every contract traded has a buyer and a seller, so heavier call volume does not mean “more bulls” — it means more call contracts changed hands than put contracts.

What it is good for is attention. Names that sit far from their usual ratio are worth a second look, which is why the ranking matters more than the raw counts.

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.
