Gamma Exposure Screener was the earlier product name for the market-wide dealer gamma discovery table. Today the GEX feature set lives inside Option Chain Analysis as part of Rank Symbols at /app/rank/symbols. The legacy path /app/gamma-exposure-screener should land users on the current Rank Symbols experience—bookmark and share the new URL.

Screenshots below are captured from the current Rank Symbols / Option Chain Analysis feature set.

What stayed the same (GEX side)

• Snapshot-first universe — Core GEX rankings and columns come from a cached prior-close style snapshot; the UI stays explicit about snapshot timing.
• Read GEX context inside the Symbols table and inspection drawer, alongside flow, positioning, volatility, and chain context.
• KPI-style context at the top of the table for regime counts and market-wide gamma scale (exact cards evolve with the product).
• Symbol drawer — Call wall, put wall, flip context, strike ladder, surfaces, and related inspection tabs—still one coherent inspection story per symbol when rank is a GEX sort.
• Live spot — Best-effort live quotes can overlay for distance and display context; they do not replace snapshot-era gamma math.

What changed (naming, URL, and vol)

• Canonical URL — Use /app/rank/symbols, not /app/gamma-exposure-screener or the retired /app/option-chain-analysis.
• Cross-sectional volatility — IV 30D, IV rank, IV percentile, and related columns sit beside GEX and flow context. Use the Symbols table and Vol drawer tab to answer “where is vol rich or cheap?” without leaving Rank. See Ranked IV and vol context for how the old “Volatility Desk” concept maps here.
• OI positioning — OI context for a selected symbol lives in the drawer's Positioning tab, not a separate cross-symbol OI rank app. See OI Change Rank (retired).

Toolbar, filters, and table

Behavior is owned by Rank Symbols today: symbol lookup, table navigation into the drawer, and entitlement-aware controls for server-backed sorts, filters, premium drawer details, and export. Prefer the in-app copy for the exact control set.

Filters dialog or Rank controls (current controls depend on the Symbols surface and account access):

Watchlist

Where the app exposes a watchlist heart on this surface, symbols you save still integrate with other TradingFlow tools that consume the shared watchlist (for example Option Trades). Do not assume parity with removed apps—cross-symbol OI Change Rank is retired.

Where to open it

In TradingFlow, open Rank → Symbols, or go directly to /app/rank/symbols. If you follow an old Gamma Exposure Screener link, you should land on the same current surface after redirect.

Gamma 敞口扫描仪 是早期对「全市场交易商 Gamma 发现表」的产品命名。当前 GEX 能力作为 期权链分析 的一部分，位于 Rank Symbols（/app/rank/symbols）中。旧路径 /app/gamma-exposure-screener 应将用户带到当前 Rank Symbols 体验——请对外书签与分享统一使用新 URL。

GEX 侧未变的能力

• 快照优先宇宙表 — 核心 GEX 排名与列来自缓存的类 T+1 快照；界面持续标明快照时间语境。
• 读取 GEX 语境 — 在 Symbols 表与检视抽屉中查看 GEX，并与资金流、持仓、波动率、期权链语境放在一起。
• 表头 KPI 风格摘要 — 用于制度占比与全市场 Gamma 体量等（具体卡片随产品迭代）。
• 标的抽屉 — 看涨墙、看跌墙、翻转语境、行权价阶梯、曲面等检视能力；当 rank 为 GEX 排序时，仍为单标的一致检视故事。
• 现货补充 — 尽力而为的实时报价可叠加用于距离与展示语境；不替代快照时代的 Gamma 计算。

已变化之处（命名、URL 与波动率）

• 规范 URL — 请使用 /app/rank/symbols，而非 /app/gamma-exposure-screener 或已下线的 /app/option-chain-analysis。
• 截面波动率 — IV 30D、IV rank、IV percentile 等与 GEX、资金流语境并列。使用 Symbols 表与 Vol 抽屉标签回答「IV 相对历史偏贵还是偏便宜」，无需离开 Rank。旧「波动率工作台」概念见 IV 与波动率语境。
• OI 持仓 — 单标的 OI 语境在抽屉的 Positioning 标签中，不再有独立跨标的 OI 排名应用；见 未平仓合约变化排名（已下线）。

工具栏、筛选与表格

具体控件集合以 Rank Symbols 线上为准：标的查找、从表格进入抽屉，以及服务器侧排序、筛选、付费抽屉详情与导出等操作的权益边界。

自选股

若该表面仍提供自选股心形入口，已保存标的仍可与消费共享自选股的其他 TradingFlow 工具（例如 期权交易）协同。不要假设与已移除的应用一致——跨标的 OI 变化排名 已下线。

在哪里打开

在 TradingFlow 中从应用导航进入 Rank → Symbols，或直接访问 /app/rank/symbols。若打开旧 Gamma 敞口扫描仪 链接，重定向后应落在当前同一表面。
