What This Category of Data Looks Like
Securities yield daily report data comes from Shanghai, Shenzhen and Beijing Stock Exchange official market APIs, China Securities Depository and Clearing Corporation public disclosure data, and compliant third-party market aggregation APIs. Full data updates complete within 1 to 2 hours after daily trading closes. Real-time market snapshots update every 10 seconds. Document structure uses structured JSON or CSV format. Included fields are: security code, security abbreviation, trading date, daily closing price (unit: RMB yuan), daily yield (unit: yield basis points), cumulative yield (unit: yield basis points). Data fields have fixed format constraints. Security code is a 6-digit numeric string. Trading date is a date string in YYYY-MM-DD format.
Constraints Imposed on Deployment and Upgrade
Data source compliance requires applying for official interface access permissions before deployment. Unauthorized data sources cannot connect to the system. Fixed update windows require scheduled sync task trigger times to match exchange data update rhythms. Triggering too early pulls incomplete temporary data. Triggering too late misses the day’s latest data. Structured field formats require defining strict parsing schemas during deployment. Missing fields or format mismatches cause data parsing failures. Large full data volumes require configuring appropriate database storage and indexing strategies during deployment to avoid query delays. Data source field changes may occur during version upgrades. Parsing logic must be updated synchronously. Otherwise, subsequent data syncs fail. Real-time market pull frequency must match interface update rhythms. Excessively frequent requests trigger rate limiting and bans.
How to Set Configuration Values
| Configuration Item | Recommended Value | Rationale for This Value |
|---|---|---|
DATA_SYNC_CRON | 0 18 * * 1-5 | Matches the 1 to 2 hour post-close update window for Shanghai and Shenzhen stock exchanges, ensures latest yield data is pulled |
PARSE_SCHEMA_VERSION | v202406 | Adapts to the current standard field structure for securities yield daily reports, prevents parsing failures from field mismatches |
API_REQUEST_RATE_LIMIT | 10 requests per minute | Complies with call limits for most securities exchange public APIs, avoids triggering rate limiting and bans |
MAX_DATA_STORAGE_DAYS | 365 days | Meets information disclosure retention requirements for the securities industry, while controlling storage resource consumption |
MODEL_CONTEXT_WINDOW | 8192 tokens | Adapts to the structured content length of securities yield daily reports, ensures full loading of data for broadcast content generation |
ERROR_RETRY_TIMES | 3 retries | Balances interface call success rate and resource consumption, avoids rate limiting from repeated requests |
The parameter values provided on this page are common starting points for configuration setup. Actual values are affected by material form, data volume, and business rules. Specific issues require targeted analysis. Testing on independent samples is recommended before finalizing values.
Three Common Configuration Errors
- Phenomenon: No available channel options appear in the OneAPI management page. Cause: No compliant API key for securities data sources is configured, or interface requests fail identity verification.
- Phenomenon: No valid yield data is generated after scheduled sync tasks trigger. Cause: The configured
DATA_SYNC_CRONtime is later than the securities exchange data update window, resulting in empty pulled data sources. - Phenomenon: When accessing grok-3 on version 4.8.20, model testing prompts an error, but formal calls run normally. Cause: The context length of the test request exceeds the configured
MODEL_CONTEXT_WINDOWthreshold. Formal calls automatically truncate non-core content.
How to Verify Successful Configuration
- Manually run a data sync task, verify that pulled raw data fields match the structure defined by the current
PARSE_SCHEMA_VERSION. - Access the OneAPI management page, confirm the configured securities market data source channel shows a normal online status.
- Submit a model test request containing simulated securities yield data, confirm the returned content format matches expected results.
- View system scheduled task logs, confirm daily sync tasks complete execution within the window matching exchange update times.
