What Is a Stock Price Alert Agent?什么是股价警报 Agent?
A Stock Price Alert Agent is an AI agent that monitors stocks or watchlists and triggers alerts when user-defined market conditions are met — price thresholds, percent moves, volume spikes, spread changes, or news events. It detects conditions, validates source data and timestamps, adds context from related signals, and delivers structured alerts. It is an event monitoring workflow, not a trading bot or investment advisor.股价警报 Agent 是一个 AI Agent,监控股票或观察列表,并在用户定义的市场条件满足时触发警报 — 价格阈值、百分比变动、成交量飙升、价差变化或新闻事件。它检测条件、验证源数据和时间戳、从相关信号添加上下文,并交付结构化警报。它是一个事件监控工作流,而非交易机器人或投资顾问。
The agent monitors multiple signal dimensions: latest price and percent change (has the stock moved meaningfully?), bid/ask and spread (is liquidity changing?), volume (is the move confirmed by activity?), WebSocket events (continuous streaming for lower-latency detection), market status (pre-market, regular hours, after-hours), and news context (is there a headline explaining the move?). Each alert preserves source timestamps, symbols, and market context.Agent 监控多个信号维度:<strong>最新价格和百分比变动</strong>(股票是否有意义地变动了?)、<strong>买卖价差</strong>(流动性是否在变化?)、<strong>成交量</strong>(波动是否被交易活动确认?)、<strong>WebSocket 事件</strong>(持续流式传输以降低延迟检测)、<strong>市场状态</strong>(盘前、常规时段、盘后)和<strong>新闻背景</strong>(是否有解释波动的头条新闻?)。每个警报保留来源时间戳、代码和市场背景。
The core insight: a raw price change is just a number. A useful alert adds context — how large is this move relative to recent ranges? Is volume confirming it? Is there related news? Is this happening during regular market hours? An alert agent that only reports "AAPL moved 3%" is incomplete. An alert agent that reports "AAPL moved 3.2% intraday, above its 30-day average daily range, with volume 1.8× average and related news detected" provides actionable monitoring context.核心洞察:原始价格变动只是一个数字。有用的警报添加上下文 — 这次波动相对于近期区间有多大?成交量是否确认了它?是否有相关新闻?这是在常规交易时段发生的吗?只报告「AAPL 涨了 3%」的警报 Agent 是不完整的。报告「AAPL 盘中上涨 3.2%,超过其 30 天平均日波动区间,成交量为均值的 1.8 倍,并检测到相关新闻」的警报 Agent 提供了可操作的监控上下文。

Why AI Agents Need Real-Time Alert Workflows为什么 AI Agent 需要实时警报工作流
1. REST Polling Can Miss Fast Moves1. REST 轮询可能错过快速波动1. REST 轮询可能错过快速波动
A REST API polled every 60 seconds can miss a price spike that happens and reverses in 30 seconds. WebSocket streaming delivers events as they happen — critical for time-sensitive alert conditions.每 60 秒轮询一次的 REST API,可能错过在 30 秒内出现并回落的价格尖峰。WebSocket 流会在事件发生时立即推送,这对时效敏感的预警条件至关重要。
2. Price Alone Is Not Enough Context2. 仅有价格不足以构成完整背景
A stock quote API tells an agent the price. An alert agent cross-references with volume, historical range, news, and market status to determine whether the move is meaningful — not just whether a number crossed an arbitrary line.股票报价 API 能告诉 Agent 当前价格。预警 Agent 还会结合成交量、历史区间、新闻和市场状态,判断波动是否具有意义,而不只是检查某个数字是否越过任意阈值。
3. Alerts Need Timestamp Validation
An alert without a verified timestamp is unreliable. The agent must confirm when the price event occurred, whether the data source is current, and whether the market was open — before triggering a notification.没有经过验证的时间戳,预警就不可靠。触发通知前,Agent 必须确认价格事件发生时间、数据源是否最新,以及当时市场是否处于交易时段。
4. News Context Explains Price Moves4. 新闻背景可以解释价格波动
A 5% drop with an earnings miss is different from a 5% drop with no news. The agent should check for related headlines and include them in the alert — turning a raw number into an explained event.财报不及预期引发的 5% 下跌,与没有新闻背景的 5% 下跌意义不同。Agent 应检查相关新闻并加入预警,把原始数字转化为有解释的事件。
5. Multi-Symbol Watchlists Need Scalable Monitoring5. 多标的观察列表需要可扩展监控
Polling 50 symbols every 30 seconds burns API quota fast. WebSocket subscriptions handle multi-symbol monitoring efficiently — only sending events when something changes.每 30 秒轮询 50 个标的会迅速消耗 API 额度。WebSocket 订阅只在发生变化时推送事件,更适合多标的监控。
6. Source-Backed Explanations6. 基于来源的解释
An alert that says "NVDA crossed $500" should include the source timestamp, the provider, the market session, and any related context. Source traceability makes alerts auditable and trustworthy.“NVDA 突破 500 美元”的预警应包含来源时间戳、提供商、交易时段和相关背景。来源可追踪性让预警能够审计并更值得信任。

Stock Price Alert Workflow股价警报工作流
Define Watchlist & Alert Conditions定义观察列表与预警条件
User defines tickers and alert rules: price above/below threshold, percent change > X%, volume spike, spread widening, crossing moving average, or news event detected. Each condition has a threshold, operator, and monitoring window.用户定义股票代码和预警规则:价格高于或低于阈值、涨跌幅超过 X%、成交量飙升、价差扩大、穿越移动平均线或检测到新闻事件。每个条件都包含阈值、运算符和监控窗口。
Discover Required Capabilities发现所需能力发现所需能力
Use QVeris Discover to find real-time price, WebSocket stream, quote data, financial news, historical price, technical indicator, and alert delivery capabilities matching the symbols and conditions.使用 QVeris Discover 查找符合标的和条件的实时价格、WebSocket 数据流、报价、金融新闻、历史价格、技术指标与预警投递能力。
Inspect Schemas Before Calling调用前检查 Schema调用前检查 Schema
Check input format, cost, latency, provider notes, market coverage, and output fields. Verify real-time vs delayed data, WebSocket subscription caps, and symbol coverage before connecting.检查输入格式、成本、延迟、提供商说明、市场覆盖和输出字段;连接前确认数据是实时还是延迟,以及 WebSocket 订阅上限和标的覆盖范围。
Connect & Monitor连接并监控
Subscribe to WebSocket streams for continuous monitoring, or poll REST endpoints on a defined interval. Pull quote data for bid/ask context. Check news endpoints for related headlines.订阅 WebSocket 数据流持续监控,或按设定周期轮询 REST 端点;获取报价以补充买卖盘背景,并查询新闻端点寻找相关新闻。
Evaluate Conditions评估触发条件
Compare incoming price/quote/volume data against defined thresholds. Check market status (pre-market, regular, after-hours). Validate timestamps before triggering evaluation logic.把实时价格、报价和成交量与设定阈值比较,并检查盘前、正常交易或盘后状态;触发判断逻辑前先验证时间戳。
Add Context补充上下文
If a condition is triggered, pull historical range context, check for related news, compare volume against average, and note the market session. Context turns a raw alert into an explained event.条件触发后,补充历史区间、相关新闻、成交量与均值对比以及交易时段。背景信息能把原始预警转化为有解释的事件。
Validate & Deliver Alert验证并投递预警
Verify timestamps, source URLs, symbol mapping, and data freshness. Send structured alert via email, Slack, webhook, dashboard, or JSON — with full source traceability and a clear "monitoring alert, not investment advice" disclaimer.核对时间戳、来源链接、代码映射和数据新鲜度,再通过邮件、Slack、Webhook、仪表盘或 JSON 投递结构化预警,并保留完整来源追踪和“仅为监控预警,并非投资建议”的声明。
