How to read it

A poor man’s covered call replaces owning the stock with a deep long-dated call, so the search is over two legs at once: which long call gives enough exposure, and which short call pays enough without capping too early.

The payoff diagram is doing the real work, because ranking these numerically is misleading — two structures with similar maximum profit can have very different break-evens and very different behaviour if the stock moves early. Compare the shapes, then look at the numbers. And remember the long leg is long-dated: the diagram assumes a volatility level that will not hold for a year.

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.
  • Payoffs use Massive fair market value estimates. FMV is not an executable price, so premiums, P&L and break-evens are theoretical.
  • Curves before expiration depend on an implied-volatility assumption held constant; in practice volatility moves with price.
