When you want to answer one simple question — "what is the standout contract activity right now?" — the Rank workbench's Contracts view is where you start. It ranks individual option contracts across the whole trading session so the most interesting action floats to the top, and it gives you a one-click path into Option Trades when you want to dig in.

Open it any time at Rank Contracts. Rank opens to this Contracts view by default.

How discovery flows

The whole point of Rank is to move you from a broad scan down to a single contract you trust, then into deeper research without rebuilding anything by hand.

The Contracts view at a glance

The Contracts view: session freshness, the brief cards, filters, and the ranked grid.

1. Session freshness — which trading session you are looking at, and whether it is live.
2. Pressure summary cards — the Contract Opportunity Brief (explained below).
3. Filters and refresh — narrow the list and control updates (paid).
4. Ranked contract grid — the leaderboard of individual contracts.

You always re-rank the whole session

Rank never shows you "leftovers." When you sort, filter, or page, you are re-ranking the complete regular trading session for the day — not reshuffling a pre-filtered scrap. That is the core trust promise of the surface: what you see is genuinely "the top contracts given these conditions," every time.

Two things to keep in mind about freshness:

• Live (latest session) is the default. Before the market opens, and on weekends or holidays, "latest" simply means the most recent completed session — so the list is never empty.
• Automatic live updates are a paid feature, available only on the latest session during market hours. Outside market hours you will see a countdown to the next open instead.

The Contract Opportunity Brief

Above the table sits a set of at-a-glance cards that summarize your currently filtered view — they always reflect your active filters and scope, never a stale slice. Think of each card as answering a different trader's question.

• Directional Pressure — the bullish-vs-bearish share of the directional flow across the filtered set. A quick read on which side is in control.
• Underlying Impact (Net DEI) — the contracts whose directional flow is largest relative to the name's typical volume, shown with both size and direction. This is how you compare a small name and a giant name fairly. See DEI.
• Turnover Shock (Vol/OI) — the contracts with the highest Vol/OI: how much traded today versus how much was already outstanding. A high ratio flags unusually fresh, concentrated activity.
• OI Impact (ΔOI DEI) — the contracts with the strongest open-interest-change impact, again with size and direction. This points to where real positions are being opened or closed.

Two honesty guardrails worth knowing:

• The "leader" cards apply a minimum liquidity bar, so near-zero-liquidity contracts cannot dominate the highlights with extreme-looking but meaningless numbers. Each card shows how many contracts qualified versus how many were excluded as too thin — the filtering is never hidden.
• Impact cards never add raw exposure across different symbols; they compare normalized, per-name impact, so the numbers stay meaningful.

The ranked contract grid

The leaderboard is "trader-first": the headline impact signal leads from the left, then direction, then turnover and positioning, then price context.

The columns are ordered so the most useful signal reads first: headline impact, then direction, then turnover and positioning, then price and validation context. Forensic and reference columns (extra exposure legs, premium legs, prior open interest, raw size, trade count, last trade time, and more) ship hidden by default and are one click away.

What you can do here:

• Page through the list — free for everyone.
• Sort by any column — click any visible column header to re-rank. Sorting is a paid feature (paging is not).
• Apply narrowing filters — by symbol, put/call, an expiry window or an exact expiration date, strike, moneyness, and minimum thresholds for activity size. Filters are paid. Expiry is exclusive: pick a preset window or an exact date, not both.
• Scope to a single symbol or a watchlist — paid; see Watchlists and Filters.
• Pick a specific trading date — instead of only the latest session. Choosing a past (historical) date is paid; those sessions are settled and do not auto-update.
• Export the current view to a spreadsheet — paid, and it mirrors exactly what is on screen.

Layout and filter choices are session-only: a fresh visit resets to the default layout and the latest-session list.

A note on mixed horizons

The ranked list deliberately blends two time horizons, and it is important you read it correctly:

• Recent flow — the intraday (slightly delayed) options activity that drives the ranking.
• Prior context — structural figures like open interest and daily volume, taken from the most recent available snapshot rather than the exact instant of each trade.

So a row is not purely real-time and not purely end-of-day. The view always makes this mixed nature explicit. Treat day-over-day open-interest change (ΔOI) as a recent-snapshot comparison, not a tick-by-tick figure.

Inspecting one contract

Click any row to open the contract inspection drawer. The drawer shell is free for everyone as a preview; the deep content inside the panels is paid. You can also share a direct link straight to a specific contract opened to a preferred tab.

The drawer identifies the exact contract, offers a one-click handoff to Option Trades, and organizes evidence into tabs.

1. Exact-contract header — the precise contract you are inspecting (symbol, date, put/call, expiration, strike).
2. Option Trades handoff — one click to carry this exact contract into Option Trades (paid).
3. Drawer analysis tabs — Flow, Positioning, and Tradeability (described below).
4. Premium detail on demand — the rich panel content unlocks for paid users.

The three tabs each answer a different validation question:

• Flow (default) — "Is this flow real, and is it opening?" Shows intraday flow in short time buckets (size, directional exposure, premium), a session-read of the day's character, and the underlying price line for context. The price line is sampled at trade prints, so it is intentionally gappy. Ambiguous mid-market ("neutral") flow is surfaced as a conviction caveat, not treated as a third direction.
• Positioning (day-over-day) — open interest over time, day-over-day change, paired bullish/bearish exposure, and a per-day table.
• Tradeability — the contract's structural snapshot: open interest, prior open interest, ΔOI, volume, Vol/OI, last price, bid/ask, implied volatility, plus IV, delta, and gamma trends and a Greeks table. This panel is clearly labeled as the latest structure snapshot for a date, so its T+1 figures are never mistaken for the intraday flow that drove the ranking. See Greeks and GEX.

The one-click handoff to Option Trades

Ranking points you to a contract; evidence is what makes it actionable. When you (as a paid user) choose Open in Option Trades from the drawer, TradingFlow carries the exact contract identity — symbol, date, put/call, expiration, strike — forward, so Option Trades opens already filtered to that one contract. No manual rebuilding of filters.

The handoff is identity-only by design: it carries the contract, not a screening lens, so you land exactly on the contract you chose. Guests land on the public Option Trades preview instead.

What to do next

You now know how to scan, validate, and hand off a single contract. To zoom out from individual contracts to the underlying names seeing the most action, continue to Using Rank: Symbols. To follow the contract you just found all the way to the tape, see Option Trades.

当你想回答一个简单的问题——"现在最突出的合约活动是什么？"——Rank 工作台的**合约（Contracts）**视图就是起点。它会对整个交易时段内的单个期权合约进行排名，让最值得关注的活动浮到最上方；当你想深入研究时，还能一键跳转到 Option Trades。

随时可在 Rank Contracts 打开它。Rank 默认就进入这个合约视图。

发现的流程

Rank 的核心用途，是带你从宽泛的扫描一路收窄到一个你信任的合约，再无需手动重建任何条件地进入更深入的研究。

合约视图概览

合约视图：时段新鲜度、概要卡片、筛选与排名网格。

1. 时段新鲜度 —— 你正在查看的是哪一个交易时段，以及它是否为实时。
2. 压力概要卡片 —— 合约机会简报（下文详述）。
3. 筛选与刷新 —— 收窄列表并控制更新（付费）。
4. 排名合约网格 —— 单个合约的排行榜。

你每次都在对整个时段重新排名

Rank 绝不会只给你"剩下的残渣"。当你排序、筛选或翻页时，你是在对当天完整的常规交易时段重新排名——而不是把某个预先筛过的碎片重新洗牌。这是这个界面的核心信任承诺：你每一次看到的，都确确实实是"在这些条件下排名最前的合约"。

关于新鲜度，有两点要记住：

• 默认是实时（最新时段）。 在开盘前、以及周末或节假日，"最新"就是指最近一个已完成的时段——所以列表永远不会是空的。
• 自动实时更新是付费功能，仅在最新时段、交易时段内可用。非交易时段则会显示距下次开盘的倒计时。

合约机会简报

表格上方有一组一目了然的卡片，用于汇总你当前筛选后的视图——它们始终反映你激活的筛选与范围，绝不会是陈旧的切片。可以把每张卡片理解为在回答交易者会问的一个不同问题。

• 方向压力（Directional Pressure） —— 筛选集合内方向性资金流的多空占比。一眼看清哪一方在掌控局面。
• 标的影响（Net DEI） —— 相对于该名称典型成交量而言、方向性资金流最大的合约，同时显示规模与方向。这是公平比较一个小名称与一个巨头名称的方式。详见 DEI。
• 换手冲击（Vol/OI） —— Vol/OI 最高的合约：今天成交量相对于已有未平仓量的比值。高比值标记出异常新鲜、集中的活动。
• 持仓影响（ΔOI DEI） —— 未平仓量变化影响最强的合约，同样显示规模与方向。它指向真实仓位被开立或平掉的地方。

两条值得了解的诚信护栏：

• "领先"卡片会应用一条最低流动性门槛，让接近零流动性的合约无法用看似极端、实则毫无意义的数字霸占高亮位。每张卡片都会显示有多少合约合格、又有多少因太薄而被排除——筛选从不隐藏。
• 影响类卡片绝不会跨不同标的累加原始敞口；它们比较的是归一化后的、按名称计的影响，从而保证数字始终有意义。

排名合约网格

排行榜以"交易者优先"排列：标志性影响信号从左侧领头，然后是方向，再是换手与持仓，最后是价格背景。

各列的排序让最有用的信号最先映入眼帘：标志性影响、然后是方向、再是换手与持仓、最后是价格与验证背景。取证类与参考类列（额外的敞口腿、权利金腿、前一日未平仓量、原始张数、成交笔数、最后成交时间等）默认隐藏，一键即可调出。

你在这里能做什么：

• 翻页浏览列表 —— 对所有人免费。
• 按任意列排序 —— 点击任何可见的列标题即可重新排名。排序是付费功能（翻页不是）。
• 应用收窄筛选 —— 按标的、看涨/看跌、到期窗口或精确到期日、行权价、价值状态（moneyness），以及活动规模的最小阈值。筛选是付费功能。 到期条件是互斥的：选择一个预设窗口或一个精确日期，不能两者兼选。
• 限定到单个标的或一个自选列表 —— 付费；详见 自选列表与筛选。
• 选择特定交易日 —— 而不只是最新时段。选择过去（历史）日期是付费功能；那些时段已结算，不会自动更新。
• 导出当前视图到电子表格 —— 付费，且导出内容与屏幕所见完全一致。

布局与筛选选择仅在当前会话内有效：重新访问会重置为默认布局与最新时段列表。

关于混合时间跨度的说明

排名列表刻意混合了两种时间跨度，你必须正确解读：

• 近期资金流 —— 驱动排名的盘中（略有延迟）期权活动。
• 历史背景 —— 像未平仓量、日成交量这类结构性数据，取自最近一份可用快照，而非每笔成交的精确时刻。

所以一行数据既不是纯实时，也不是纯收盘后的。该视图始终明确标注这种混合特性。请把未平仓量的日间变化（ΔOI）当作一次近期快照比较，而非逐笔数据。

检视单个合约

点击任意一行即可打开合约检视抽屉。抽屉外壳对所有人免费，作为预览；面板内的深度内容为付费。你也可以分享一个直接链接，跳到某个特定合约并打开你偏好的标签页。

抽屉会标明确切的合约、提供一键跳转 Option Trades，并把证据组织进各个标签页。

1. 确切合约标头 —— 你正在检视的精确合约（标的、日期、看涨/看跌、到期日、行权价）。
2. Option Trades 跳转 —— 一键把这个确切合约带入 Option Trades（付费）。
3. 抽屉分析标签页 —— Flow、Positioning 与 Tradeability（下文详述）。
4. 按需的高级详情 —— 丰富的面板内容对付费用户解锁。

三个标签页各自回答一个不同的验证问题：

• Flow（默认） —— "这股资金流是真的吗？它在开仓吗？" 以短时间桶展示盘中资金流（张数、方向性敞口、权利金）、一段对当天特征的时段解读，以及作为背景的标的价格线。价格线按成交打印取样，因此故意是断续的。模棱两可的盘中价（"中性"）资金流会作为信念质量提示呈现，而不被当作第三种方向。
• Positioning（日间） —— 未平仓量随时间的变化、日间变化、配对的多空敞口，以及一张按日表格。
• Tradeability —— 合约的结构性快照：未平仓量、前一日未平仓量、ΔOI、成交量、Vol/OI、最新价、买卖价、隐含波动率，外加 IV、Delta、Gamma 趋势与一张希腊字母表。该面板被清楚标注为某一日期的最新结构快照，所以它的 T+1 数据绝不会被误认为驱动排名的盘中资金流。详见 Greeks 与 GEX。

一键跳转到 Option Trades

排名为你指向一个合约；而证据才让它变得可执行。 当你（作为付费用户）从抽屉中选择 Open in Option Trades 时，TradingFlow 会把确切的合约身份——标的、日期、看涨/看跌、到期日、行权价——一并带过去，使 Option Trades 打开时已经筛选到那一个合约。无需手动重建筛选条件。

这个跳转在设计上是仅传递身份的：它带的是合约本身，而不是某个筛选视角，从而让你恰好落在所选的合约上。访客则会落在公开的 Option Trades 预览页。
