Scanning for the best iron condors across the market
Recorded in cvforge on May 16, 2026 by ConvexValue · Published July 25, 2026
Iron condors ranked by expected return, risk-reward and probability of profit, with open interest and volume filters to keep untradeable strikes out.
Exact prompt
I want to scan for the best iron condors - rank by expected return, risk-reward, probability-of-profit - and also filter for open interest and volume
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
fair_market_value, strike_price, expiration_date, contract_type, delta, implied_volatility, open_interest, day_volume
How to read it
Four legs, ranked three ways, with liquidity filters — this is a scan no fixed screener menu offers, and it is the most-watched demo in the library for that reason.
The liquidity filters are not a detail. A condor with an attractive theoretical return on low-volume, low-open-interest strikes deserves less weight. Ranking is arithmetic on Massive fair market value estimates, not executable prices, so treat the ordering as a shortlist and check each leg’s actual market elsewhere before believing the numbers.
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.
- Rankings are arithmetic on Massive fair market value estimates, not advice. FMV is not an executable price, and nothing here accounts for your account, margin, assignment risk or taxes.
- Multi-leg structures are valued leg by leg using FMV estimates. cvforge has no option quote or last-trade data with which to model fills or transaction costs.
