Five-minute bars on a single MU option contract
Recorded in cvforge on June 25, 2026 by ConvexValue · Published July 25, 2026
Intraday bars for one specific contract — the MU 1200 call expiring tomorrow — charted over the past week rather than the underlying stock.
Exact prompt
Give me a chart of the 5m bars starting last week of the $MU strike 1200 call expiring tomorrow.
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
Needs the Research data plan, which adds end-of-day historical options aggregates. The rest of the build runs on the free tier.
Fields used
day_volume, open_interest, implied_volatility, delta, strike_price, expiration_date, contract_type, underlying_price
How to read it
Most charts here describe the chain in aggregate. This one drills into a single contract and charts its own price history, which is what you want when you hold that contract rather than a view on the underlying.
Two things to note. Intraday option bars need the Research plan, unlike the snapshot builds. And a near-expiry contract’s bars are jumpy by nature — with a day to go, small moves in the underlying produce large percentage moves in the option, so the volatility on screen is the instrument, not the data.
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 call/put split describes contracts traded, not net direction: every contract has a buyer and a seller.
