Volume vs open interest, ranked your way
“Surface tickers where today's option volume is more than 5× their open interest, and rank by the ratio.”
If your scanner can't rank by it, describe it in English
Your screener has a fixed menu of filters — your next idea isn't on it. In cvforge you describe the scan in plain English and the AI you already use (Claude Code, Codex…) builds it, with options data — volume, open interest, Greeks, IV, fair value — already connected.
Scans your screener's menu doesn't have
Each of these started as one plain-English prompt and became a working tool on connected options data.
IV in full context
“Render a live IV surface for AAPL across all expirations and strikes.”
Positioning by strike
“Chart SPX open interest by strike for the next monthly — calls vs puts.”
How it works
Three steps from a prompt to a working market tool.
- 1
Bring the AI you already use
Claude, Codex, Gemini, Grok, and other agents work with cvforge. You do not need to learn a new AI tool.
- 2
Describe the tool you want
Ask for the dashboard, scanner, chart, or payoff view in plain English. cvforge supplies the data and setup your AI needs to build it.
- 3
Keep what you build
Your tools are saved on your machine, ready to reopen, modify, and reuse when the market changes.
Questions
Is this live streaming data? +
No — cvforge works on options snapshots (fair value, volume, open interest, Greeks, IV) at research cadence. Scans re-run on refresh, not on the tape.
What does it cost? +
The app is free. The free data tier (20 requests/hour) needs no card. Paid tiers add request volume, a personal API key with MCP access, and — on the Research tier — historical options data.
Which AI does the building? +
The one you already use — Claude Code and Codex are first-class; Gemini, Grok, and Cursor work too. cvforge supplies the data connection and the ready-to-run setup.
Do I need to know how to code? +
No. You describe the scan in plain English and the AI writes the implementation. If you do code, you can edit alongside it.
Where do my scanners live? +
On your machine. Tools persist locally — reopen, tweak, and rerun them whenever you want.
Type the filter your screener refuses to run
Free desktop app, free data tier, no card. Describe the scan; keep the tool.
