There is no separate Volatility Desk route. Cross-sectional IV rank, IV percentile, and vol-focused drawer tabs live on /app/option-chain-analysis with the same universe grid as GEX.
The standalone OI Change Rank app and /app/oi-change-rank are removed from the product (2026). Per-symbol OI history now lives in Option Chain Analysis as OI Time Machine in the symbol drawer.
The old Gamma Exposure Screener URL redirects to Option Chain Analysis. Same snapshot GEX universe, now with unified rank/drawer URLs and cross-sectional vol on one grid.
One route (`/app/option-chain-analysis`) combines GEX universe ranking, cross-sectional IV columns, and a symbol drawer—using a unified `rank` + `drawerTab` URL contract. GEX inspection includes OI Time Machine (`oi-timeline`); vol sorts open a vol-rank drawer (Overview, Term structure, Earnings).
Symbol-level analysis—under Option flow analysis in the app—ranks the universe by options flow for any session date, with a public symbol drawer, Day trend charts, and an Option Trades handoff. The default list preview is open to all; sorting, full filters, and CSV are premium.
Contract-level analysis gives you a ranked view of options flow at the contract level. See which top contracts lead the market with mixed-horizon intraday flow and prior-session context, complete with exact-contract inspection.
The Option Trades app streams real-time options flow with 6 market KPI cards, 13-dimension filters, watchlist, persistent preferences, and Live Flow WebSocket mode — so you can track blocks and unusual activity as it happens.
