Gamma Exposure Screener was the earlier product name for the market-wide dealer gamma discovery table. Today the canonical name and route are Option Chain Analysis at /app/option-chain-analysis. The legacy path /app/gamma-exposure-screener redirects there—bookmark and share the new URL.

Screenshots below are captured from Option Chain Analysis today (same route the legacy GEX URL redirects to).

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.
• Rank the list by GEX / structure sorts such as market cap, gross or net gamma, distance to the zero-gamma / flip level, and related views the app exposes under rank.
• 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/option-chain-analysis, not /app/gamma-exposure-screener.
• Cross-sectional volatility — IV rank, IV percentile, and related columns are on the same grid as GEX. Switch list rank to a vol sort to prioritize “where is vol rich or cheap?” without leaving the page. See Ranked IV and vol context for how the old “Volatility Desk” concept maps here.
• OI Time Machine — Historical OI for a selected symbol lives in the drawer (drawerTab=oi-timeline when deep-linking), not a separate cross-symbol OI rank app. See OI Change Rank (retired).

Toolbar, filters, and table

Behavior is owned by Option Chain Analysis today: symbol lookup, underlying-type filters where applicable, chart + table navigation into the drawer, and entitlement-aware controls for changing rank / filters on the full screener. Prefer the in-app copy for the exact control set.

Filters dialog (underlying type, gross GEX range, gamma regime—same control as on /app/option-chain-analysis today):

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 Option Chain Analysis from the app navigation or go directly to /app/option-chain-analysis. If you follow an old Gamma Exposure Screener link, you should land on the same unified page 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。当前的规范名称与路由为 期权链分析（/app/option-chain-analysis）。旧路径 /app/gamma-exposure-screener 会重定向至此——请对外书签与分享统一使用新 URL。

下方截图来自当前期权链分析（与旧 Gamma 路径重定向后的同一路由）；行为与地址栏遵循统一查询约定（rank、drawerTab、selectedSymbol、underlyingType），不再使用独立的 mode 切换。

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。
• 列表排序 — 在 rank 下使用市值、总/净 Gamma、距零 Gamma / 翻转距离等 GEX/结构类排序及同类产品暴露的视图。
• 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/option-chain-analysis，而非 /app/gamma-exposure-screener。
• 截面波动率 — IV rank、IV percentile 等与 GEX 同一张主表。将列表 rank 换为波动率排序即可优先回答「IV 相对历史偏贵还是偏便宜」，无需换路由。旧「波动率工作台」概念见 IV 与波动率语境。
• OI 时光机 — 单标的历史 OI 在抽屉中（深链常见 drawerTab=oi-timeline），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 Option Chain Analysis 线上为准：标的查找、适用的标的类型筛选、从图表/表格进入抽屉，以及在完整扫描仪上变更 rank / 筛选时的权益边界等。

筛选弹窗（标的类型、总 GEX 区间、Gamma 制度等——与当前 /app/option-chain-analysis 一致）：

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 Option Chain Analysis，或直接访问 /app/option-chain-analysis。若打开旧 Gamma 敞口扫描仪 链接，重定向后应落在同一统一页面。
