There is no separate Volatility Desk route. Cross-sectional IV rank, IV percentile, and vol-focused drawer context now live inside Rank Symbols at /app/rank/symbols.
The standalone OI Change Rank app and /app/oi-change-rank are removed from the product (2026). Per-symbol OI context now lives in the Positioning tab of the Rank Symbols inspection drawer.
The old Gamma Exposure Screener naming now maps to GEX features inside Rank Symbols. Use /app/rank/symbols for current GEX, volatility, OI positioning, and chain inspection.
Option Chain Analysis is now a feature set inside Rank Symbols (`/app/rank/symbols`): GEX, volatility, OI positioning, and chain tabs live in the symbol inspection drawer alongside flow-ranked discovery.
Symbol-level analysis is now the Symbols tab of the Rank workbench. It ranks the universe by option flow, adds integrated GEX/vol/OI/chain inspection tabs, and keeps Option Trades handoff and CSV export behind the right access boundaries.
Contract-level analysis is the Contracts tab of the Rank workbench. It ranks specific option contracts with intraday flow, retained snapshot dates, OI/volume context, exact-contract inspection, and Option Trades handoff.
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.
