Looking for option clues before a Bloom Energy move
Recorded in cvforge on June 30, 2026 by ConvexValue · Published July 25, 2026
A heatmap of BE option activity plotted with the stock price and news, built to ask whether the option market showed anything before a sharp move.
Exact prompt
Show me a heatmap and visualizations to understand unusual options activity on Bloom Energy ( $BE ) along with stock price and news - I want to see if there were any clues for the recent price action.
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
The prompt asks a hindsight question honestly: were there clues. Putting the activity heatmap on the same timeline as price and news is the only way to answer it, because the answer depends entirely on ordering.
Be strict with yourself reading this. After a large move you will find elevated activity somewhere in the preceding days, because there is always activity somewhere — the question is whether it was unusual at the time, not whether it looks meaningful now. The chart supports that check; it does not perform it for you.
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.
