美股日内交易台的交付物Deliverables for a US-equity intraday desk

把当日的催化剂，整理成台面可以直接读的交付物。The day's catalysts, organised into deliverables a desk can read.

三样东西：交易时段内的事件雷达邮件、每个交易日开盘前的一封简报、交易时段内约每秒更新的实时观察名单。它们读的是同一套对象——标的 · 时段 · 催化剂 · 信号。每一项都带时间戳与 as of 时钟。这是给人看的决策支持，不含任何交易指令。Three things: intraday e-mail issues during US market hours, one brief before every open, and a live web page that updates about once per second during the session. They read the same four objects — Symbol · Session · Catalyst · Signal. Every item carries a time-stamp and an 'as of' clock. It is decision support for a person, and it carries no trade instruction.

地基The foundation

同一条记录：在邮件里是一段文字，在看板上是一行。One record: a paragraph in the e-mail, a row on the page.

四个对象定义了三个界面上的一切。这不是三个产品共用一个品牌，而是三个界面共用一套记账。下面列出的都是你在产品里会亲眼看到的属性名称，不是它们背后的算法。Four objects define everything on all three surfaces. It is not three products sharing a brand; it is three surfaces sharing one set of books. What follows are the property names you will actually see in the product — not the arithmetic behind them.

  • 标的Symbol一只在美国上市的股票。承载最新价、跳空、相对成交量、与 VWAP 的关系、成交节奏等可见属性。A US-listed equity. Carries visible properties such as last, gap, relative volume, its relationship to VWAP, and volume cadence.
  • 时段Session盘前 · 开盘 · 常规 · 收盘四个阶段。同一只标的，在不同阶段被以不同方式读。Premarket, opening, regular, closing. The same symbol is read differently in each phase.
  • 催化剂Catalyst使这只标的今天区别于昨天的事件。带类别标签与出处，并可被平实语言展开。The event that makes this name different today than it was yesterday. Carries a class chip, a provenance, and a plain-language read.
  • 信号Signal由上述三者派生的、可观察的形态判断。它是一段读法，永远不是交易指令。An observable read derived from the three above. It is a reading, never a trade instruction.

三个界面Three surfaces

三个界面，一套对象、一套催化剂分类、一个时钟。Three surfaces, one set of objects, one catalyst taxonomy, one clock.

在盘前简报里读到的名字，是事件雷达邮件里的同一个对象，也是实时观察名单上的同一行。升级 Pro 不是买第四个产品，而是把同一套系统多打开一个面。三个界面均已投入使用。The name you read in the brief before the open is the same object in the intraday issue and the same row on the live page. Upgrading to Pro is not a fourth product; it opens one more surface onto the same system. All three surfaces are in service.

数据、方法与交付节奏Data, method and cadence

能被你自己核验的那一部分，我们才写在页面上：交付节奏。We publish the part you can check yourself: the delivery cadence.

数据：机构级行情源的美股与期权综合实时数据，交易时段内持续更新。方法：自有的催化剂本体与状态模型，配合 AI 辅助生成的平实语言解读，用于公告与新闻。下表是可核验的服务水平陈述：什么形态、多久一次、在哪个时段。Data: consolidated real-time US equities and options market data from institutional-grade feeds, updated continuously through the session. Method: a proprietary catalyst ontology and regime models, with AI-assisted plain-language reads of filings and news. The table below is a verifiable service-level statement — what form, how often, in which window.

数据Data

服务状态条的三种状态The three states of the service strip
  • 正常OK实时观察名单服务此刻可达。需要账号才能进入页面。The Live Watchlist service is reachable right now. An account is still required to open the page.
  • 异常Not OK服务明确报告不可用。若持续，请来信 alerts@catalystdesk.ai。The service explicitly reports that it is unavailable. If it persists, write to alerts@catalystdesk.ai.
  • 未确认Unconfirmed本页此刻无法得到确定答案（首次结果返回前、超时、或本地网络阻断）。这不是一次故障判定。This page cannot get a definite answer right now — before the first result returns, on a timeout, or when the local network blocks the check. It is not a verdict of failure.
  • 这条只说一件事One question only本条仅显示服务可达性，不代表任何标的的数据新鲜度；页内的延迟或陈旧由看板自身的 Data status 列显式标注。This strip shows service reachability only. It says nothing about the freshness of any individual symbol — delayed or stale data is labelled on the page itself, in the Data status column.

两封邮件的解剖Anatomy of the two e-mails

一封事件雷达邮件里有什么；开盘前那一封又不是什么。What one intraday issue contains — and what the pre-open one is not.

下图是版面线框，不是截图：页面上不会出现真实简报画面、真实数值，也不会出现任何内部阈值、参数或窗口长度。候选按本台的读法排序，次序是阅读辅助，不是优先级指令。The figure is a wireframe, not a screenshot: no real issue, no real numbers, and no internal threshold, parameter or window length appears anywhere on this page. Candidates are ranked by the desk's read; the order is a reading aid, not a priority instruction.

  1. 01 排序候选01 Ranked candidates当日候选按本台读法排序，每条独立成块。The day's candidates, ranked by the desk's read, each as its own block.
  2. 02 催化剂类别标签02 Catalyst-class chip一枚标签，说明这只标的今天为什么不同。One chip that says why this name is different today.
  3. 03 时段感知的形态分类03 Session-phase-aware setup taxonomy盘前、开盘、常规、收盘各有各的分类，不混用。Premarket, opening, regular and closing each carry their own taxonomy; they are not interchangeable.
  4. 04 跳空与区间背景04 Gap and range context这只标的今天所处的位置，放在它自己的区间里看。Where the name sits today, read against its own range.
  5. 05 相对成交量背景05 Relative-volume context今天的参与度，相对于它自己的常态。Today's participation, relative to this name's own normal.
  6. 06 分时走势缩略图06 Intraday sparkline一条小图交代形状，不替代任何图表工具。A small line that carries the shape. It does not replace a charting tool.
  7. 07 确信度矩阵07 Conviction matrix多个维度并排呈现，刻意不折叠成单一评分。Dimensions shown side by side, deliberately not collapsed into a single score.
  8. 08 期权背景08 Options context隐含波动幅度、看跌/看涨姿态、异常活动、gamma 聚集区。Implied move, put/call posture, unusual activity, gamma clusters.
  9. 09 同板块联动标的09 Sympathy peers同一催化剂下可能被一起推动的名字。Names that may move alongside the same catalyst.
  10. 10 历史类比10 Historical analogues过往时段里形状相近的情形，供对照，不作外推。Comparable situations from past sessions, offered for comparison, not for extrapolation.
  11. 11 宏观脉络与板块热力11 Macro tape and sector heatmap今天这封简报所处的大环境。The environment the rest of the issue sits inside.
  12. 12 与昨日的差异 · 深读 · 时间戳与退订12 What is different from yesterday · deep read · time-stamp and unsubscribe全刊最短、也最该先读的一段；随后是对公告与新闻的 AI 辅助平实解读；每封结尾都有 as of 时钟与一键退订，位置固定。The shortest block in the issue and the one to read first; then an AI-assisted plain-language read of filings and news; every issue closes with an 'as of' clock and a one-click unsubscribe link, always in the same place.
  • 盘前简报 · 送达窗口Premarket Brief · delivery window每个交易日一封，约在美东 08:45–09:10 之间送达，落在开盘之前。One e-mail every trading day, delivered roughly between 08:45 and 09:10 ET — before the open.
  • 盘前简报 · 内容Premarket Brief · contents全市场与 S&P 500 的跳空与状态背景；按流通盘分层的跳空筛选；隔夜有催化剂标的的参考事实：跳空档位、空头持仓背景、跳空回补倾向。Market-wide and S&P 500 gap and regime context; a float-tiered gap screen; and reference facts for names with overnight catalysts — gap tier, short-interest context and gap-fill tendencies.
  • 盘前简报 · 边界Premarket Brief · scope开盘前到手的是参考事实，不是当日候选清单，也不是交易指令。开盘之后由事件雷达接手。What lands before the open is reference facts — not the day's candidate list, and not a trade instruction. After the open, Event Radar takes over.

边界Boundaries

适合谁，以及这套东西明确不做什么。Who it fits, and what it explicitly does not do.

把边界写在正文里而不是只压在页脚，是因为读者常从中部锚点直接进来。以下几条同时是产品主张与免责声明。The boundary is stated in the body rather than left to the footer, because readers often arrive mid-page from an anchor. The lines below are product claims and disclaimers at the same time.

适用For

  • 美股日内主动交易者：自己做判断，只需要把当日结构整理好。Active US-equity intraday traders who make their own calls and want the day's structure organised.
  • 两三个人的小型交易台：需要一份共同的、带时间戳的台面语言。Small desks of two or three who need one shared, time-stamped vocabulary.
  • 中英双语团队：实时观察名单与本站中英并置；邮件以中文为主，市场术语保留英文原形。Bilingual teams: the Live Watchlist and this site ship Simplified Chinese and English side by side; the e-mails are Chinese-first with market terms kept in English.

不做什么What it does not do

  • 不给交易指令No trade instructions任何界面上的任何内容都不是买入、卖出或持有的指示。Nothing on any surface tells you to buy, sell or hold.
  • 不代客下单No execution不连接券商账户、不代为下单、不管理资金，也不提供个性化投资建议。No account connection, no order placement, no money management, and no personalised investment advice.
  • 不公布内部口径No internal parameters不公开任何阈值、参数、窗口长度、权重或计算口径。No threshold, parameter, window length, weight or formula is published.
  • 不给成效数字No performance figures不发布业绩、胜率、收益或用户数量，也不使用任何证言。No performance, win-rate, return or user-count figure, and no testimonials.

任何界面上的任何内容都不是交易指令；这是给人看的决策支持。如果这样的边界正合适，下面是两档方案。Nothing on any surface is a trade instruction; it is decision support for a person. If that boundary suits you, here are the two tiers.

价格Pricing

两档：邮件免费，实时观察名单按账号开通。Two tiers: the e-mails are free, the live page is granted per account.

常见问题FAQ

我会收到什么？多久一封？What do I get, and how often?

免费档含两份邮件产品。盘前简报：每个交易日开盘前一封，约在美东 08:45–09:10 之间送达。事件雷达：美股交易时段内的邮件简报，来自分钟节律的扫描，封数随当日盘面而变，没有固定配额。Pro 另含实时观察名单网页，交易时段内约每秒更新一次。Free covers two e-mail products. The Premarket Brief: one e-mail every trading day before the open, delivered roughly between 08:45 and 09:10 ET. Event Radar: e-mail issues during US market hours, from a minute-cadence scan; how many arrive depends on the day, and there is no fixed quota. Pro adds the Live Watchlist web page, which updates about once per second during the session.

这是投资建议吗？Is this investment advice?

不是。三个界面上的内容都是人的决策支持：市场信息与分析。我们不发出交易指令，不连接券商账户，不代为下单，也不评估任何人的财务状况或给出个性化建议。所有判断、下单与其后果由使用者自行承担。No. Everything on all three surfaces is human decision support — market information and analysis. We issue no trade instruction, we do not connect to brokerage accounts, we place no orders, and we do not assess anyone's circumstances or give personalised advice. Every decision, order and outcome remains the user's own.

数据从哪来？为什么不点名？Where does the data come from, and why don't you name the sources?

机构级行情源的美股与期权综合实时数据，交易时段内持续更新。我们不点名任何行情源、新闻源、券商或模型供应商——这是我们对供应关系一贯的处理方式，和数据质量无关。判断数据的办法是看页面：每个界面都带时间戳与 as of 时钟；实时观察名单的 Data status 列会把延迟或陈旧的数据显式标注。Consolidated real-time US equities and options market data from institutional-grade feeds, updated continuously through the session. We do not name any market-data feed, news source, broker or model provider — that is how we treat supplier relationships generally, and it says nothing about data quality. The way to judge the data is to look at the page: every surface is time-stamped and carries an 'as of' clock, and on the Live Watchlist the Data status column labels delayed or stale data.

为什么不公布阈值、参数或计算口径？Why aren't thresholds, parameters or formulas published?

催化剂本体与状态模型是本台自有的工作成果，公开口径会直接削弱它们的效力。我们把这写成明确的产品政策，而不是含糊带过：营销页面上只出现名称与交付物——催化剂类别、形态分类、列名；任何数值口径、窗口长度与权重都不会出现在这里。每列的含义在登录后的产品内给出。The catalyst ontology and the regime models are our own work, and publishing their arithmetic would degrade it. We state this as explicit policy rather than leaving it vague: the marketing pages carry names and artefacts only — catalyst classes, setup taxonomies, column names. No formula, threshold, window length or weight appears on them. What each column means is explained inside the product after sign-in.

数据延迟或中断时会怎样？What happens when data is delayed or interrupted?

实时观察名单会把受影响的行标注为延迟或陈旧，Data status 列就是为此存在的；邮件里的内容带自己的时间戳，因此你总能判断它是何时的读数。本页的服务状态条只回答一件事：实时观察名单服务此刻是否可达——可达、明确不可用，或本页此刻无法确认。它不代表任何一只标的的数据新鲜度。The Live Watchlist labels affected rows as delayed or stale — that is what the Data status column is for — and the content of an e-mail carries its own time-stamps, so you can always tell when a reading was taken. The service-status strip on this page answers one question only: whether the Live Watchlist service is reachable right now — reachable, explicitly unavailable, or unconfirmed from here. It says nothing about the freshness of any individual symbol.

实时观察名单怎么开通？为什么是邀请制？How do I get the Live Watchlist, and why is it by invitation?

发信到 alerts@catalystdesk.ai，主题写「Pro access request」，说明使用场景与希望开通的邮箱地址。访问权按账号发放，开通后用该邮箱以验证码登录。邀请制的原因是我们逐个开通、逐个确认账号，而不是产品的状态——三个界面均已投入使用。Write to alerts@catalystdesk.ai with the subject 'Pro access request', telling us how you intend to use it and which address to enable. Access is granted per account; once enabled, you sign in with that address and an e-mail code. It is by invitation because we enable and confirm accounts one at a time — it is not a statement about the product's state. All three surfaces are in service.

Pro 多少钱？What does Pro cost?

目前没有公开价格，卡片支付也尚未开放；价格确定后会直接出现在本页的定价区块中，届时同步公布计费条款（续费、变更生效时点与取消的生效方式）。在此之前，Pro 通过邮件申请开通，也因此不存在自动扣款。There is no public price yet and card payments are not open. When pricing is set it will appear in the pricing block on this page, and the billing terms — renewal, when changes take effect, and how cancellation works — will be published at the same time. Until then Pro is arranged by e-mail, so there is nothing that can auto-charge you.

如何取消？How do I cancel?

免费档：点击任意一封邮件里的一键退订链接，立即生效，不需要说明理由。Pro：发信到 alerts@catalystdesk.ai 即可，随时。两者都不需要打电话。Free: click the one-click unsubscribe link in any issue — it takes effect immediately and needs no reason. Pro: write to alerts@catalystdesk.ai, any time. Neither requires a phone call.

免费档是不是 Pro 的阉割版？Is Free just a cut-down Pro?

不是。免费档是两份完整的邮件产品，内容不做降级，也不换成另一套数据。两档的差别是交付形态：免费拿两封邮件，Pro 多拿一个实时观察名单。No. Free is two complete e-mail products — nothing is downgraded and no second-class data is substituted. The difference between the tiers is the form of delivery: Free gets the e-mails, Pro adds the live web page.

我不在美东时区，时间怎么看？邮件会不会进垃圾箱？I'm not in the US Eastern zone — and will the e-mails land in spam?

本站与产品内的所有时刻都是美东时间（ET），并统一带 ET 后缀，方便换算。发件地址是 alerts@catalystdesk.ai，建议加入联系人或通讯录。订阅采用双重确认：提交后先收到一封确认信，点击其中的链接订阅才成立——这一步同时也有助于后续送达。Every time on this site and in the products is US Eastern (ET) and is written with the ET suffix, so it converts cleanly. We send from alerts@catalystdesk.ai; adding it to your contacts helps. Subscription is double opt-in: you first receive a confirmation e-mail and the subscription starts only when you click the link inside it — a step that also helps later deliverability.

支持中文吗？需要安装什么吗？一个账号能几个人用？Is it bilingual, do I need to install anything, and can a team share one account?

实时观察名单与本站中英并置：列标签、详情面板与本页文案都是中文在上、英文在下；邮件以中文为主，市场通用术语（VWAP、TSMA、RVOL 等）保留英文原形。浏览器即可使用，无需安装。访问权按账号发放、会话按账号独立，团队请按席位申请。The Live Watchlist and this site ship Simplified Chinese above English — column labels, the detail panel and this page; the e-mails are Chinese-first with standard market terms (VWAP, TSMA, RVOL and the like) kept in English.

你们会公布业绩或胜率吗？Will you publish performance or win rates?

不会。本产品不发出交易指令，因此也不存在可归属于它的交易结果；任何胜率或收益数字都会与这一点自相矛盾。我们能提供的可验证事实是交付节奏、时间戳口径与状态标注，这些都写在页面上，你可以自己核对。No. The product issues no trade instructions, so there are no outcomes to attribute to it; any win-rate or return figure would contradict that. What we can offer instead are verifiable facts — delivery cadence, time-stamping and status labelling — all stated on this page so you can check them yourself.
