Connect a market-data source through a custom GPT Action or an application built with OpenAI tool calling—then make every answer carry a symbol, price, currency, market session, source, and timestamp. 通过自定义 GPT Action，或在使用 OpenAI tool calling 的应用中连接行情数据源，并让每次回答都包含股票代码、价格、币种、交易时段、来源与时间戳。
Use this guide to choose an integration path, define freshness correctly, implement the tool contract, and validate what ChatGPT says when market conditions are messy.本指南帮助你选择接入方式、正确定义数据新鲜度、实现工具契约，并验证 ChatGPT 在复杂市场状态下给出的回答。
The right path depends on where the conversation lives and how much control the workflow needs. 选择取决于对话发生在哪里，以及工作流需要多少控制权。
Best for a focused assistant used inside ChatGPT. Describe your quote endpoint with OpenAPI, configure authentication, and test it in Preview. OpenAI documents that Actions connect GPTs to external APIs through authentication plus a schema. 适合直接在 ChatGPT 内使用的专用助手。用 OpenAPI 描述行情端点，配置认证，再在 Preview 中测试。OpenAI 官方说明，Action 通过认证配置和 schema 把 GPT 接到外部 API。
Read OpenAI’s GPT Actions setup 阅读 OpenAI GPT Actions 配置说明Best for a website, agent, dashboard, or automated workflow. Your server exposes a quote function to the model, validates its arguments, calls the data provider, and submits the result for a sourced natural-language answer. 适合网站、Agent、看板或自动化流程。服务器向模型声明行情函数，校验参数、调用数据源，再把结果交回模型生成带来源的自然语言答案。
Read OpenAI’s function calling guide 阅读 OpenAI function calling 指南Adding real-time stock market data to ChatGPT is not a direct model-to-exchange connection. A production design separates language reasoning from deterministic validation, provider access, and evidence formatting.为 ChatGPT 接入实时股票市场数据，并不是让模型直接连接交易所。生产架构需要把语言推理与确定性的参数校验、数据源访问和证据格式化分开。
ChatGPT identifies whether the user wants a current quote, a historical comparison, market status, or a broader research task. It should ask for clarification when a symbol, exchange, or time horizon is ambiguous.ChatGPT 判断用户要查询当前行情、历史对比、市场状态，还是更完整的研究任务。若股票代码、交易所或时间范围有歧义，应先追问确认。
A narrow schema constrains symbols, exchanges, fields, and permitted operations. This layer rejects malformed input, applies user and workspace policy, and keeps read-only retrieval separate from trading.边界清晰的 schema 约束股票代码、交易所、返回字段和允许操作。本层拒绝异常输入、执行用户与工作区策略，并把只读查询和交易严格分离。
Server-side code owns credentials, provider selection, entitlement checks, retries, normalization, and caching. If providers use different names for sessions or timestamps, the adapter maps them into one stable response.服务端代码负责凭证、数据源选择、授权检查、重试、标准化和缓存。若不同数据源对交易时段或时间戳使用不同字段，适配层应统一为稳定结构。
The final response combines the quote with its currency, as-of time, session, delay status, and source. The model may explain the result, but it must not silently replace missing fields or present stale data as current.最终回答把行情与币种、数据时间、交易时段、延迟状态和来源一起呈现。模型可以解释结果，但不能悄悄补齐缺失字段，也不能把旧数据说成当前数据。
Let the model decide when a quote is needed; let application code decide whether and how the request is safe to execute. The returned JSON—not model memory—is the source of truth for the price.由模型判断何时需要行情；由应用代码判断请求是否可以执行以及如何执行。价格的事实来源是工具返回的 JSON，而不是模型记忆。
A price without timing context can be confidently wrong. Require enough metadata to explain what the number represents. 缺少时间上下文的价格很容易造成误导。应强制返回足够的元数据，说明这个数字究竟代表什么。
| Field 字段 | Why it matters 为什么重要 | Example shape 示例形式 |
|---|---|---|
| symbol, exchange | Disambiguates tickers across venues. 避免不同交易所出现同名代码时混淆。 | NASDAQ:AAPL |
| price, currency | Prevents an unlabeled number from being treated as USD. 防止把没有币种标识的数字默认当成美元。 | number + ISO currency |
| as_of | Shows when the provider observed or published the value. 说明数据源观察或发布该值的时间。 | ISO 8601 timestamp |
| session | Separates regular, pre-market, after-hours, and closed states. 区分正常交易、盘前、盘后和休市。 | regular / pre / post / closed |
| delay, source | Makes licensing and freshness limits visible. 把授权范围和新鲜度限制明确展示出来。 | delay seconds + provider |
The best stock market API for ChatGPT is the one whose coverage, entitlement, freshness, and response metadata match the questions your users ask. A cheap quote endpoint may be sufficient for casual lookup but unsuitable for alerts, compliance-sensitive research, or redistribution.最适合 ChatGPT 的股票行情 API，应在市场覆盖、授权、新鲜度和响应元数据上匹配用户问题。低成本行情端点可能足够应付普通查询，却未必适合提醒、合规敏感研究或数据再分发。
| Criterion评估维度 | Questions to verify需要核实的问题 | Failure if ignored忽略后的风险 |
|---|---|---|
| Market coverage市场覆盖 | Which exchanges, instruments, countries, and asset classes are included?覆盖哪些交易所、证券类型、国家和资产类别？ | The same ticker resolves to the wrong venue or no result.同名代码被解析到错误市场，或完全没有结果。 |
| Freshness新鲜度 | Is the value real-time, delayed, indicative, snapshot, or previous close for this entitlement?在当前授权下，返回的是实时、延迟、指示性、快照还是前收盘价？ | ChatGPT labels an old value as a live stock price.ChatGPT 把旧价格误称为实时股价。 |
| Session detail交易时段 | Can the API distinguish regular, pre-market, after-hours, halted, and closed?API 能否区分正常交易、盘前、盘后、停牌和休市？ | A post-market value is compared with a regular-session close without explanation.盘后价格与正常收盘价被直接比较，却没有说明口径。 |
| Licensing数据授权 | May values be displayed to end users, cached, logged, or redistributed?数据能否向终端用户展示、缓存、记录或再分发？ | A technically working integration violates display terms.技术上可用的集成却违反了展示条款。 |
| Operational fit运维适配 | What are the rate limits, timeout behavior, status page, and support path?限流、超时行为、状态页和支持渠道分别是什么？ | Peak traffic becomes unexplained missing or repeated quotes.高峰流量导致行情缺失或重复，却无法定位原因。 |
Do not copy a universal “real-time” label from a provider homepage. Verify the specific exchange, endpoint, account tier, and intended display use in the provider’s official documentation and agreement.不要直接照搬数据源首页上的“实时”宣传语。应在官方文档和协议中核实具体交易所、端点、账户级别及预期展示用途。
Start with quote lookup, daily change, session status, and a timestamp. Treat charts, news, filings, screening, and trading as separate capabilities with separate permissions. 先支持行情查询、日内涨跌、交易时段状态和时间戳。图表、新闻、公告、选股与交易应作为权限独立的能力处理。
Check exchange coverage, entitlement, delay, redistribution terms, uptime, rate limits, and whether timestamps and session status are returned. “Real-time” must match your plan and market. 核对交易所覆盖、数据授权、延迟、再分发条款、可用性、限流，以及是否返回时间戳和交易状态。“实时”的定义必须与你购买的套餐和市场一致。
Accept a symbol or query plus an optional exchange. Return a stable JSON object. Keep provider keys server-side and never ask the model to assemble secret-bearing URLs. 输入股票代码或查询词，并可选指定交易所；输出稳定的 JSON。数据源密钥只保留在服务端，不要让模型拼接带密钥的 URL。
Require the answer to state the as-of time, currency, session, and source. If data is stale, missing, or ambiguous, the assistant should say so rather than infer a current price. 要求回答注明数据时间、币种、交易时段与来源。若数据过期、缺失或代码有歧义，助手应明确说明，不得推测当前价格。
Test weekends, holidays, halts, pre-market and after-hours, invalid symbols, duplicate ticker names, provider timeouts, rate limits, and split-adjusted historical values. 测试周末、节假日、停牌、盘前盘后、无效代码、重名代码、数据源超时、限流，以及复权历史数据。
Log request ID, selected capability, provider, latency, status, and data timestamp—without leaking keys. Cache only for a duration compatible with the promised freshness. 记录请求 ID、所选能力、数据源、延迟、状态和数据时间戳，但不要泄露密钥。缓存时长必须符合对用户承诺的新鲜度。
This illustrative tool definition is intentionally provider-neutral. Your application—not the model—owns authentication, symbol normalization, retries, entitlements, and the final provider request. 下面的工具定义是与数据源无关的示例。认证、代码标准化、重试、授权判断和最终的数据源请求，都应由你的应用而不是模型负责。
Separate factual market retrieval from recommendations, trading, suitability assessment, and regulated activities. 应把客观行情查询与推荐、交易、适当性评估及受监管活动明确分开。

A good tool call can still produce a misleading answer if the model hides timing and scope. Give the assistant a compact output policy that is easy to test.即使工具调用正确，如果模型隐藏时间和口径，最终回答仍可能误导。应给助手一套简洁、可测试的输出规则。
Example Company (EXCH:XYZ) is shown at 123.45 USD. The quote is marked regular session and was observed at 14:32:08 America/New_York. Source: Example Provider. Data status: real-time under the configured entitlement.示例公司（EXCH:XYZ）当前显示为 123.45 USD。该行情标记为正常交易时段，数据时间为 14:32:08 America/New_York。来源：示例数据源。数据状态：在当前授权下为实时。
This is a formatting example, not an observed market quote. Production values must come from the tool result.这只是格式示例，不是真实观测行情。生产环境中的数值必须来自工具返回结果。
“For any request containing current, live, now, today, latest, pre-market, or after-hours price intent, call the quote tool before answering. Never recall a price from conversation history. If the result lacks an as-of timestamp, source, or session status, state that the quote cannot be verified as current.”“凡请求包含当前、实时、现在、今天、最新、盘前或盘后价格意图，回答前必须调用行情工具。不得从对话历史中回忆价格。如果结果缺少数据时间、来源或交易时段状态，应说明无法验证该行情是否为当前数据。”
QVeris can help an agent discover market-data capabilities, inspect their inputs and outputs, and call the selected tool through a unified interface. This is useful when one workflow may later expand from quotes to filings, news, indicators, or alerts. QVeris 可帮助 Agent 发现市场数据能力、检查输入输出，并通过统一接口调用选定工具。当工作流可能从行情扩展到公告、新闻、指标或提醒时，这种方式尤其有用。
Use the live stock page to inspect quote freshness, charts, and market-session context. 通过实时股票页检查行情新鲜度、图表和交易时段上下文。

Read the market data MCP guide 阅读市场数据 MCP 指南A reliable ChatGPT stock-data workflow makes these trade-offs explicit. Optimizing only for the fastest model response can increase quote staleness, provider cost, or operational risk.可靠的 ChatGPT 股票数据工作流必须明确这些取舍。只追求模型最快回答，可能增加行情陈旧、数据成本或运维风险。
Set cache policy by user intent and feed rights. A repeated educational lookup may tolerate a short cache; a market alert may require a new request. Return both the provider timestamp and any cache age so the assistant can describe the result honestly.根据用户意图和数据授权设置缓存策略。重复的教学查询可能允许短时缓存，市场提醒则可能必须重新请求。应同时返回数据源时间戳和缓存年龄，让助手如实描述结果。
Use a bounded timeout and at most a controlled retry for transient failures. If a fallback provider has different coverage or delay, expose that substitution in the response instead of making the sources appear equivalent.设置明确超时，并只对暂时性故障进行有限重试。若备用数据源在覆盖或延迟上不同，应在回答中说明替换，不能让不同来源看起来完全等价。
Prevent one prompt from expanding into hundreds of symbols. Cap list size, separate batch endpoints, deduplicate repeated symbols, and monitor provider calls per conversation. Ask for confirmation before expensive scans.避免一个提示词扩展成数百个股票查询。限制列表规模、为批量查询使用独立端点、去重重复代码，并监控每次对话的数据源调用数。高成本扫描前应要求确认。
Store market-data keys in a server-side secret manager or managed connection. Scope credentials to read-only data where possible, rotate them, redact request headers from logs, and never return provider secrets to ChatGPT.把市场数据密钥保存在服务端密钥管理器或托管连接中。尽可能使用只读权限，定期轮换，在日志中隐藏请求头，并且绝不能把数据源密钥返回给 ChatGPT。
A quote symbol is often low sensitivity, but watchlists, positions, account identifiers, and strategy prompts may not be. Minimize what is sent to the provider and document what external service receives.单个股票代码通常敏感度较低，但自选列表、持仓、账户标识和策略提示词可能并非如此。应减少发送给数据源的内容，并明确哪些外部服务会接收数据。
Keep the quote tool read-only. If trading is ever added, use a separate tool, stronger authentication, explicit confirmation, idempotency, position and risk checks, and a complete audit trail.行情工具应保持只读。如果未来增加交易能力，应使用独立工具、更强认证、明确确认、幂等控制、持仓与风险检查，以及完整审计记录。
| Symptom现象 | Likely cause可能原因 | What to fix修复方法 |
|---|---|---|
| ChatGPT gives a price without calling the toolChatGPT 未调用工具就给出价格 | Tool description or assistant instructions do not identify freshness intent.工具描述或助手指令没有明确识别实时意图。 | Add trigger terms and require a tool call for current-price questions; test paraphrases, not only one prompt.补充触发词，并要求当前价格问题必须调用工具；测试多种表达，而不只是一个提示词。 |
| The quote is correct but labeled “live” incorrectly价格正确，但被错误标成“实时” | The adapter discarded provider delay or entitlement metadata.适配层丢弃了数据源延迟或授权信息。 | Preserve data status and make the model repeat it; never infer real-time status from a recent timestamp alone.保留数据状态并要求模型复述；不能仅凭时间戳较新就推断为实时。 |
| A symbol returns the wrong company股票代码返回了错误公司 | Ticker resolution ignored exchange or country context.代码解析忽略了交易所或国家上下文。 | Return candidate matches and ask the user to disambiguate before the quote call.先返回候选结果，在调用行情前让用户确认。 |
| Prices change between two turns with no explanation两轮对话价格变化，却没有解释 | One answer came from cache or a different session/feed.其中一次来自缓存，或使用了不同交易时段/数据流。 | Display as-of time, cache age, session, and source on every answer.每次回答都显示数据时间、缓存年龄、交易时段与来源。 |
| The assistant retries until rate-limited助手持续重试直至触发限流 | The tool loop lacks terminal error states and retry limits.工具循环缺少终止错误状态和重试上限。 | Classify errors as retryable or terminal, cap attempts, and return a user-readable failure reason.把错误分为可重试和终止型，限制尝试次数，并返回用户可理解的失败原因。 |
A useful evaluation set measures more than whether an API returned HTTP 200. Test tool selection, argument accuracy, evidence preservation, language quality, and safe failure behavior.有效的评测不应只检查 API 是否返回 HTTP 200，还要测试工具选择、参数准确性、证据保留、语言质量和安全失败行为。
Do not publish the integration until every supported market has an explicit freshness definition, every quote includes traceable metadata, and every tested provider failure ends with an honest user-facing response. Re-run the set whenever the provider, schema, tool description, model, or caching policy changes.在每个支持市场都有明确新鲜度定义、每条行情都具备可追踪元数据、每种已测试的数据源故障都能得到诚实的用户回答之前，不应上线。更换数据源、schema、工具描述、模型或缓存策略后，都要重新执行评测。
Do not assume it does. For a repeatable application, connect a trusted market-data source and retrieve the quote at answer time. Display the source, market session, and timestamp. 不要作此假设。若要构建可重复运行的应用，应连接可信行情数据源，在回答时即时查询，并展示来源、交易时段和时间戳。
Yes, through a GPT Action when the endpoint, authentication, and OpenAPI schema satisfy ChatGPT’s requirements and workspace policy. Test the action in Preview before sharing it. 可以。只要端点、认证和 OpenAPI schema 符合 ChatGPT 要求及工作区策略，就能通过 GPT Action 调用。分享前应先在 Preview 中测试。
The exact meaning depends on the exchange, feed, and entitlement. A provider may return a current value for one venue but delayed or indicative data for another. Preserve the provider timestamp and delay metadata instead of applying one label globally. 具体含义取决于交易所、数据流和授权。同一数据源可能对某个市场提供实时值，对另一个市场只提供延迟或指示性数据。因此应保留来源时间戳与延迟信息，不能统一笼统标注。
Usually no. Keep read-only market retrieval separate from order entry. Trading requires stronger identity, authorization, confirmations, risk controls, audit trails, and regulatory review. 通常不应。只读行情查询应与下单分离。交易还需要更严格的身份认证、授权、确认、风险控制、审计记录和监管评估。
Return the latest available value with its timestamp and session status, and state whether it is the previous close, an after-hours quote, or another provider-defined value. 返回最新可用值，同时给出时间戳和交易时段状态，并说明它是前收盘价、盘后行情，还是数据源定义的其他数值。
