Volume versus open interest · Demo

A watchlist ranked by volume-to-open-interest ratio

Recorded in cvforge on June 24, 2026 by ConvexValue · Published July 25, 2026

An editable watchlist across the top, a table of its highest volume/OI contracts underneath — a monitoring tool for names you already care about.

Exact prompt

Give me a dashboard that does the following: it has a watchlist on the top and lets me add/remove stocks (lets start with $MU, $NVDA, $DRAM, $SNDK) it shows a table of top options based on volume / open interest 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.

Fields used

day_volume, open_interest, strike_price, expiration_date, contract_type, implied_volatility, delta

How to read it

This inverts the screener pattern. A market-wide scan tells you where activity is; a watchlist tells you what is happening in the names you follow, which is the question you have most days.

Being able to add and remove tickers is what makes it a tool rather than a snapshot. Note the request cost though: each name is its own chain lookup, so a long watchlist on the free tier’s hourly limit is the one thing likely to make this build feel slow.

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.
