Option Chain Analysis in TradingFlow is the unified discovery app where dealer gamma structure and implied-volatility context share one ranked universe. You get a snapshot-first GEX screener, best-effort live spot enrichment for context, and cross-sectional vol columns and sorts on the same grid—no separate “vol app” URL. A symbol drawer carries you from summary levels through surfaces, option-chain style columns, and per-symbol OI history.

What Option Chain Analysis does

The heavy lifting uses a cached market snapshot (T+1 style) for the GEX universe: thousands of symbols stay fast because core rankings and columns come from a precomputed layer, not a full recompute on every load. The UI is honest about snapshot timing; where rows show live spot quotes, that is best-effort context for distances and display—it does not replace the underlying snapshot gamma math.

• Rank the universe by GEX / structure sorts—such as market cap, gross or net gamma, distance to the zero-gamma / flip level, and squeeze-style views—or by vol sorts (IV rank, IV percentile) on the same page.
• Read one table that joins GEX columns with IV30 and 1y IV rank / IV percentile (cross-sectional “how rich or cheap is vol” next to “how are dealers positioned”).
• Filter by underlying type (stock, ETF, index) where the product exposes it, alongside the active list sort.
• Open any symbol in a drawer: inspection stays coherent per symbol, with the tab set below depending on how you are sorting the list.

Filters dialog (underlying type, gross GEX bounds, gamma regime—you apply these before the ranked universe refreshes):

Links and state (shareable URLs)

Stable deep links on /app/option-chain-analysis use a single search contract—no mode switch in the long run:

• rank — list sort, either a GEX/structure mode (e.g. market cap, gross/net gamma, flip distance, squeeze) or a vol mode (iv_rank, iv_percentile).
• selectedSymbol — which symbol the drawer is open on, when you share or bookmark.
• drawerTab — the active tab inside the drawer (GEX inspection vs vol-rank tabs; see below).
• underlyingType — optional filter (STOCK, ETF, INDEX) when applicable.

Legacy vol links from older releases (?mode=vol, volRank, volDrawerTab) are rewritten in the app to the same unified rank + drawerTab shape—you are still on Option Chain Analysis, not a second product.

One grid for structure and vol

Cross-sectional volatility is columns and sort keys on the main Option Chain Analysis table, not a separate “vol only” screen. If you want the names with the highest IV rank, you change the list sort to a vol rank—still on /app/option-chain-analysis. Discovery stays in one place: you change how the universe is ordered, not which route you are on.

Deeper single-symbol vol analytics inside the drawer continue to roll out; the grid already answers “where is IV rich or cheap cross-sectionally?” in line with the shipped columns.

Same ranked universe with GEX and vol columns on one grid:

Symbol drawer: GEX inspection vs vol-rank

Behavior depends on the active list sort (rank).

When rank is a GEX / structure sort (default)

The GEX symbol drawer includes tabs such as summary, strike ladder, OI and chain views, gamma and IV expiry surfaces, vol context, skew, and a broker-style option chain table—one inspection payload per symbol, as the product defines it.

OI Time Machine (per symbol)

For historical open interest on the selected symbol, use the OI Time Machine tab. In URL state it appears as drawerTab=oi-timeline, if you are sharing a deep link.

Retired: A standalone cross-symbol OI rank list and the old mode=oi entry are not in the product. There is no supported /app/oi-change-rank app route. Do not expect a separate “OI change rank” URL; per-symbol OI history lives in this drawer, on OI Time Machine / oi-timeline. The inspection sheet (GEX-rank context) is where those tabs—including OI Time Machine—live once you open a row; see the symbol drawer figure at the top of this article.

When rank is a vol sort (iv_rank, iv_percentile)

The app opens the vol-rank drawer for the selected symbol, with tabs such as Overview, Term structure, and Earnings—still on /app/option-chain-analysis, driven by the same rank + drawerTab state. Some of the deeper single-symbol vol experiences here remain scaffolded; expect the grid to be the most complete cross-sectional vol surface for now.

Access at a glance

• Browsing the table preview and opening the symbol drawer (including public inspection where shown) are part of the discovery surface for anonymous and signed-in users.
• Mutations that drive the full screener—changing rank, submitting symbol or filter changes that repopulate the full list, and similar—may be entitlement-gated. Deep links that include gated control params can fall back to preview list behavior while still allowing public drawer navigation (selectedSymbol / drawerTab) where the product allows.

Exact gating can evolve—rely on in-app messaging for your account.

---

Legacy URLs and redirects

• /app/gamma-exposure-screener → /app/option-chain-analysis (replace). Prefer linking /app/option-chain-analysis in docs and shares.
• Old vol query styles (mode=vol, volRank, volDrawerTab) normalize to rank + vol-style drawerTab as described above; the address bar is meant to end up on the unified params, not a permanent parallel “vol page.”

---

Where to find it (with examples)

In TradingFlow, open Option Chain Analysis from the app nav or go to /app/option-chain-analysis.

Examples (illustrations only; behavior follows in-app rules):

• Vol-focused universe: https://tradingflow.com/app/option-chain-analysis?rank=iv_rank
• GEX + drawer + a GEX tab (paths vary by tab name): a link might combine selectedSymbol=…, rank=gross or another GEX rank, and a drawerTab such as summary or oi-timeline for OI Time Machine.

Try a GEX sort for regime and wall context, then switch to IV rank or IV percentile to compare vol richness on the same universe, and open the drawer on any name that stands out.

For how the legacy Gamma Exposure Screener name maps to the same surface (redirect, unified rank / drawerTab), see Gamma Exposure Screener (legacy name)—kept as a lineage article, not a second live app URL.

TradingFlow 的 期权链分析（Option Chain Analysis） 在交易商 Gamma 结构与隐含波动率语境上共用同一条排名宇宙。你会得到快照优先的 GEX 筛选、对距离与阅读友好的最佳努力实时现货补充，以及同一张主表上的截面波动率列与排序——没有第二套「波动率专用」应用 URL。标的抽屉从摘要价位延伸到曲面、类券商期权链列，以及单标的历史未平仓合约（OI）洞察。

期权链分析能做什么

应用围绕缓存的全市场快照（T+1 风格）构建 GEX 宇宙：排名与核心列来自预计算层，而不是每次打开页面都现场重算。界面会标明快照时点；在可用时，产品会以最佳努力方式用实时现货丰富行数据，用于距离与阅读上下文——不会改写底层快照 Gamma 的数学含义。

• 全市场排名 — 既可按 GEX / 结构类排序（如市值、总/净 Gamma、距零 Gamma/翻转位距离、挤压相关视角等），也可按 IV rank、IV percentile 等 波动率 排序，且不离开 /app/option-chain-analysis。
• 一张表看结构 + 波动率 — 同一张表同时呈现 GEX 列与 IV30、1y IV rank、1y IV percentile 等字段，用于对照「交易商如何站位」与「IV 在全截面贵不贵」。
• 标的类型筛选 — 在产品支持时，可按股票、ETF、指数等与当前列表排序组合使用。
• 打开任意标的抽屉 — 具体标签页由当前列表的 rank 决定（见下）。

筛选弹窗（标的类型、总 GEX 区间、Gamma 制度等——在列表重新排序/刷新前应用）：

链接与状态（可分享的 URL）

在 /app/option-chain-analysis 上，稳定的深度链接使用统一的查询约定（长期不依赖 mode 开关）：

• rank — 列表排序，可为 GEX/结构（如市值、总/净 Gamma、距翻转距离、挤压相关等）或 波动率（IV rank、IV percentile）。
• selectedSymbol — 分享或书签时，抽屉打开在哪只标的。
• drawerTab — 抽屉内当前标签（GEX 检视与 vol-rank 标签各自一套；见下）。
• underlyingType — 可选标的类型筛选（股票、ETF、指数），与代码中 STOCK / ETF / INDEX 对应。

旧版波动率相关参数（?mode=vol、volRank、volDrawerTab）会在应用内重写为统一的 rank + drawerTab ——你仍在期权链分析这同一个产品面，而不是另一条「波动率专用」路由。

---

结构与波动率共用一张表

截面波动率是主期权链分析表上的列与排序键，而不是单独的「只做波动率」产品屏。若要看当下 IV rank 最高的标的，只需把列表排序切到波动率 rank ——仍在 /app/option-chain-analysis。这样 discovery 始终在同一入口：你改的是如何排序全市场，而不是换哪条应用路由。

抽屉内更重的单标的波动率能力仍在逐步补齐；当前以主表上的截面 IV 列为最完整、可操作的发现面。

同一张排名表上，GEX 列与波动率列并排呈现：

标的抽屉：GEX 检视 与 波动率 rank 模式

表现取决于当前列表的 rank。

当 rank 为 GEX / 结构类排序（默认）

GEX 标的抽屉包含摘要、行权价阶梯、未平仓与链、Gamma/IV 到期曲面、单标的 IV/RV 语境、偏度、类券商期权链等标签——在产品的数据契约下，通常对应每个标的一次连贯的检视。

OI 时光机（单标的）

要查看选中标的的历史未平仓合约演变，请使用抽屉中的 OI 时光机（OI Time Machine）。在可分享的 URL 中，对应参数常写作 drawerTab=oi-timeline（便于深度链接与书签）。

已下线： 独立的跨标的 OI 排名列表与旧入口 mode=oi 不属于当前产品；没有可依赖的 /app/oi-change-rank 应用路由。请勿期待单独的「OI 变化排名」URL；单标的 OI 历史在本应用的 GEX 抽屉中，通过 OI 时光机 / oi-timeline 完成。从行打开后的检视抽屉（GEX 排序语境下）承载上述标签页；图示见文首 标的抽屉 截图。

当 rank 为波动率类排序（iv_rank、iv_percentile）

对选中标的，应用使用 vol-rank 抽屉，包含 概览、期限结构、与财报相关 等标签——仍在 /app/option-chain-analysis，由同一套 rank + drawerTab 状态驱动。其中部分更深的单标的波动率体验可能仍为脚手架/迭代中；截面发现仍以主表为优先。

访问权限概览

• 浏览主表预览与在适用范围内打开标的抽屉（含公开可看的检视内容）属于对匿名与登录用户开放的发现面。
• 会改变全表列表的交互（例如提交会重算完整筛选器结果的排名/筛选变更等）可能受权益门控。若深度链接带有需门控的控件参数，页面可能对列表回退为预览行为，同时仍尽量保留 selectedSymbol / drawerTab 等公开抽屉导航（以应用内行为为准）。

具体门控以应用内对你账号的提示为准。

---

旧链接与重定向

• 旧版 /app/gamma-exposure-screener 会重定向到 /app/option-chain-analysis（建议对外统一使用新路径）。
• 历史 mode=vol / volRank / volDrawerTab 组合会归一为 rank 与 vol 风格的 drawerTab；产品倾向让地址栏最终落在统一参数上，而不是长期并行保留一套「仅波动率页」的查询方式。

---

在哪里打开（示例）

在应用导航中打开 Option Chain Analysis（期权链分析） ，或直接访问 /app/option-chain-analysis。

示例（仅作说明，实际以应用规则为准）：

• 以 IV rank 为主： https://tradingflow.com/app/option-chain-analysis?rank=iv_rank
• GEX 排序 + 打开某标的 + 某 GEX 标签时，深度链接会组合 selectedSymbol=…、GEX 类的 rank=…（如 gross 等）以及如 summary、oi-timeline（OI 时光机）等 drawerTab。

可先使用 GEX 排序做制度与墙位类观察，再切换到 IV rank 或 IV percentile 在同一宇宙上比较波动率贵贱，并对任意突出标的打开抽屉。
