NVDA and MU call positioning overlaid on a delta axis
Recorded in cvforge on June 11, 2026 by ConvexValue · Published July 25, 2026
Two names’ call positioning on one chart using delta rather than strike for the x-axis — the change that makes stocks at different prices comparable.
Exact prompt
I want a overlaid comparison of NVDA and MU call positioning - use delta for x-axis
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, contract_type, underlying_price
How to read it
The insight is the axis. NVDA and MU trade at very different prices, so overlaying them on strike puts their activity in different regions of the chart and the comparison says nothing. Delta normalises position relative to spot, and the two profiles become directly comparable.
Once aligned, the shape is the read: activity clustered near 0.5 delta is positioning close to the money, activity out at 0.1 is cheap-upside speculation, and seeing which name skews further out is the point of the overlay.
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.
