Update timing varies by feature, provider, market session, entitlement, cache state, request volume, and the source’s own publication schedule. The ranges below are operational guidance—not service-level guarantees and not promises of real-time or never-stale data.

| Surface | Typical application timing | Important qualifications |
|---|---|---|
| Intraday charts | Seconds to several minutes | Fetched on request and cached by interval, generally for short windows. Yahoo is primary and Polygon fallback. Bars can lag, be incomplete, or be unavailable. |
| Daily / weekly / monthly charts | Minutes to end-of-day or later | Polygon history and Yahoo recent bars are merged where available. Higher-timeframe bars may remain open until their period ends. |
| Alpaca quote / trade surfaces | Seconds to several minutes | Timing depends on the implemented surface, session, feed entitlement, exchange coverage, network conditions, and cache. “Latest” does not guarantee consolidated real time. |
| Stock-page market fields | Minutes to hours | Page and provider caches may persist. Check the market timestamp or “as of” field rather than assuming the page-load time is the quote time. |
| Cryptocurrency surfaces | Minutes, sometimes longer | CoinGecko timing varies by endpoint, plan, upstream venue data, cache, and outage status. |
| Surface | Cautious range | Important qualifications |
|---|---|---|
| News feeds | Several minutes to several hours | Publication ingestion, provider indexing, deduplication, pagination, and application caching all affect appearance time. |
| Reddit / trending attention | Roughly 15 minutes to several hours | Rate limits, source access, aggregation windows, and validation can delay or omit mentions. |
| Google Trends signals | Roughly 30 minutes to a day or more | Google samples and normalizes interest data; retries and rate limits can extend the interval. |
| AI narrative | On request or cached | Generation time is not data time. A new summary can describe older prices, filings, estimates, or headlines supplied to the model. |
| Data class | Cautious range | Important qualifications |
|---|---|---|
| Company fundamentals | After issuer reporting; often quarterly or annual | Provider ingestion may follow the filing. Values can be mapped differently, amended, or restated. Daily retrieval does not make quarterly facts daily. |
| Analyst estimates | Intraday to several days | Only where an implemented provider returns them. Consensus changes depend on contributor and provider processing schedules. |
| SEC company filings | After EDGAR acceptance and ingestion | Usually discoverable after SEC publication, but parsing, indexing, amendments, rate limits, and outages can delay display. |
| Form 13F holdings | Quarterly, commonly up to 45 days after quarter end | 13F data is inherently backward-looking and may not represent a manager’s current position. |
A request can trigger a calculation immediately, but “calculated now” does not mean “all source observations are current now.” Stock-page scores and report scores use available inputs; chart-based observations depend on available price history; client-side calculators use the values entered by the user. Reports may also consume cached or period-dated source data.
A report generated at 2:00 p.m. may use a quote stamped 1:58 p.m., a daily bar still in progress, financial statements for the quarter ended three months earlier, and a filing accepted the prior evening. The report is “generated at 2:00 p.m.”; it is not accurate to call every input 2:00 p.m. data. If a provider is unavailable, a cached value or a feature-specific fallback may be used—or the field may be missing. Always evaluate each source date independently.
No timing range above guarantees delivery. Rate limits, provider or exchange outages, entitlement changes, scheduled maintenance, symbol changes, malformed responses, parser errors, and network failures can make data stale or unavailable without warning.
