围绕时间戳、市场覆盖、数据时效和故障处理，为 WorkBuddy 构建可靠的实时股票数据工作流。
What real-time stock data changes for WorkBuddy
WorkBuddy can reason, remember context, schedule work, and invoke tools, but a language model's training data is not a live market feed. A market-data connection closes that freshness gap for research summaries, watchlist checks, volatility alerts, dashboard prototyping, and data-quality investigations.
The key boundary is equally important: this use case provides evidence for analysis; it does not authorize trading. Quotes can be delayed, venue-specific, consolidated, adjusted, or contractually restricted. Treat “real time” as a documented property of a feed and subscription, not a label inferred from a recent-looking number.
Research and monitoring
Fresh snapshots, watchlists, market-state summaries, chart inputs, and explainable alerts.
Orders and portfolio actions
Execution needs separate credentials, approvals, risk checks, idempotency, and audit policy.
Reference architecture: feed → adapter → tool → WorkBuddy
Keep the agent-facing interface stable even when the provider changes. Normalize upstream responses before they reach WorkBuddy, and preserve the raw provider identity in the result envelope.
Licensed feed
Quotes, trades, bars, status
Adapter
Normalize symbols and time
Read-only tool
Validate and bound calls
WorkBuddy
Reason over attributed data
Why not send a WebSocket directly into the model?
A continuous feed is application state, not conversational context. Let a stream consumer handle reconnects, ordering, deduplication, backpressure, and cache updates. WorkBuddy should request a bounded snapshot or aggregate through a tool. This controls token use and makes calls reproducible.
Implementation: connect a market-data tool in six steps
1. Define freshness before choosing a provider
Specify asset class, exchanges, trade or quote data, maximum acceptable age, extended-hours behavior, history depth, and whether results will be displayed or redistributed. Then compare provider documentation and entitlements. A developer plan may expose a different feed from a paid production plan.
2. Build a provider-neutral adapter
Map vendor fields into one typed contract. Normalize symbol conventions, timestamps, currency, session status, corporate-action adjustments, and typed errors. Keep provider-specific fields under an optional metadata object.
3. Expose narrow read tools
Start with operations such as get_quote, get_bars, and get_market_status. Put limits on symbols, date ranges, granularity, and response size. Do not expose arbitrary URLs, arbitrary SQL, or provider administration.
4. Connect the adapter to WorkBuddy
Expose the adapter through the tool, automation, or HTTP connection supported by your WorkBuddy environment. Keep authentication server-side and grant only the read operations this workflow needs.
5. Prompt for evidence, not confidence
Require WorkBuddy to state symbol, value type, event time, receipt time, provider/feed, session, currency, and delay classification. If data is stale or the market is closed, the answer should say so before interpreting the move.
6. Test degraded states
Use recorded fixtures for deterministic tests, then run an opt-in live smoke test. Exercise rate limiting, provider timeouts, malformed payloads, symbol not found, closed sessions, stale cache, partial batches, and reconnect recovery.
Design a tool contract WorkBuddy can reason over
A price without its meaning is unsafe. Return an explicit envelope rather than a bare number.
| Field | Purpose | Example meaning |
|---|---|---|
symbol | Resolved instrument identity | Ticker plus exchange when ambiguous |
last / bid / ask | Typed price values | Never collapse quote and trade |
event_time | When the market event occurred | Provider timestamp in UTC |
received_at | When your adapter received it | Supports age and transport checks |
source | Provider and feed provenance | Avoids false equivalence |
session | Pre, regular, post, or closed | Explains apparent inactivity |
freshness | Live, delayed, stale, or unknown | Computed from explicit policy |
Three high-value WorkBuddy workflows
Watchlist with market context
Combine fresh snapshots with prior-close bars and explicitly label pre-market data. Schedule the brief, but make “no fresh data” a valid outcome.
Explain conflicting prices
Have WorkBuddy compare feed, venue, timestamp, quote versus trade, session, and adjustment policy instead of choosing one value blindly.
Prototype a live dashboard
Let WorkBuddy build against a provider-independent schema, with explicit loading, delayed, stale, disconnected, and closed states.
Read-only threshold alerts
Evaluate rules in an application service, then let WorkBuddy explain attributed triggers. Keep execution credentials entirely absent.
Use QVeris provider discovery to review available data sources, then verify coverage and licensing in the chosen provider's official documentation. Use QVeris tool discovery to find the narrow read operation your workflow needs.
Production controls: freshness, safety, cost, and rights
Use two clocks
Compare provider event time with gateway receipt time. A newly received payload can still contain an old event.
Keep credentials server-side
Never place API keys in prompts, logs, skills, examples, or version control. Scope and rotate them.
Budget calls deliberately
Batch symbols, cache only within a declared TTL, cap history windows, and observe rate-limit headers.
Respect data rights
Display, storage, derived-data, and redistribution rights differ. Match implementation to the actual agreement.
Release checklist
- Every value includes type, currency, source, event time, receipt time, and session.
- The tool rejects invalid symbols, non-finite values, reversed windows, and oversized batches.
- Stale, delayed, disconnected, partial, and closed states are visible.
- Market data and order execution use different services, credentials, and approval paths.
- Recorded fixtures cover normal and degraded behavior without requiring an open market.
Troubleshooting the failures that look like “bad AI”
| Symptom | Likely cause | Check |
|---|---|---|
| Price differs from another app | Different feed, venue, value type, or delay | Compare provenance and timestamps |
| Data never changes | Closed session, stale cache, lost stream | Inspect session, TTL, heartbeat |
| WorkBuddy cannot see the tool | Server disabled, startup failure, or filter | Review config, stderr, and tool list |
| Calls time out in batches | Provider limit or oversized request | Bound batch size; retry with jitter |
If WorkBuddy runs several market-data calls in parallel, enable that only for read-only operations and only after checking the adapter for shared-state races. Serialize any workflow that mutates shared state.
Frequently asked questions
Can WorkBuddy get real-time stock prices by itself?
Not as an inherent model capability. Connect a licensed data source through a controlled read-only tool, then return timestamps, feed identity, and freshness with each result.
Which WorkBuddy connection method should I use?
Use the narrowest tool, automation, or HTTP interface available in your current WorkBuddy deployment. Product capabilities can change, so verify the supported method in the product before implementation.
Should I expose a live WebSocket directly to WorkBuddy?
Usually no. Maintain streaming state in an application-side consumer and expose bounded snapshots or aggregates. This makes ordering, retries, backpressure, cancellation, and token use manageable.
Can this workflow place trades?
No. This design is intentionally read-only. If execution is added later, isolate it behind separate services, credentials, explicit confirmation, risk controls, idempotency, and audit logs.
How do I test when markets are closed?
Replay timestamped fixtures and simulate market-session states. Keep a separate opt-in live smoke test for connectivity; do not make the main test suite depend on an open exchange.
Turn a market feed into a tool WorkBuddy can trust
Start with one read-only quote operation, one freshness rule, and one attributed response envelope. Validate it before widening symbols or history.
