What the data for this category looks like
Precious metal market data sources include domestic precious metal exchanges, international industry associations, and professional market aggregation APIs. Update rhythm aligns with the trading hours of corresponding markets. Domestic listed products push data in real time during continuous trading sessions, and generate daily settlement data after market close. International products update continuously across time zones. Each data entry includes the standard product code, trading market identifier, latest transaction price, settlement reference price, daily price fluctuation range, and data update timestamp. Field units vary by product type: common units for gold, platinum, and similar products are yuan/gram; units for silver and similar products are yuan/kilogram.
Constraints on Deployment and Upgrade
The multi-source nature of precious metal market data requires configuring multiple data source adapters during deployment to support dynamic switching between domestic and international market APIs. The real-time update feature requires setting reasonable polling intervals or long connection parameters during deployment to avoid exceeding API rate limiting thresholds. Differences in units across product types require adding unit standardization conversion logic during upgrades to unify broadcast output formats. Changes in data update rhythm during market closures require configuring scheduled policy switching scripts to ensure compliant daily report data is generated outside trading hours. Data timeliness requirements include setting short timeouts and retry mechanisms during deployment to avoid broadcast delays that compromise content accuracy.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
DATA_FETCH_INTERVAL | 30 seconds | Matches the market update rhythm of domestic precious metal continuous trading sessions, avoids exceeding rate limiting thresholds of most market APIs |
UNIFY_OUTPUT_UNIT | yuan/gram | Unifies the output unit for mainstream products such as gold and platinum, simplifies format processing logic for daily report broadcasts |
PARSE_DATA_TIMEOUT_SECONDS | 10 seconds | Adapts to the typical response delay range of most market APIs, prevents single data fetch processes from being interrupted by timeouts |
DAILY_REPORT_CRON | 0 0 8 * * * | Matches the common habit of investors checking daily reports in the morning, ensures complete daily reports are generated at a fixed time each day |
DATASOURCE_FALLBACK_ENABLE | Enabled | Automatically switches to a backup data source when the primary market API returns an exception, ensures daily report generation service remains uninterrupted |
REQUIRED_DATA_FIELDS | ["symbol","market","price","settle_price","update_time"] | Filters redundant fields, retains only core data items required for daily reports, reduces processing overhead |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Configuration Errors
- Symptom: Calls to precious metal market APIs return a 400 error code, prompting that the parameter format is invalid. Cause: Failed to pass product codes with market prefixes as required by the API, confused coding rules for domestic and international products, leading to API verification failure.
- Symptom: Daily report generation tasks time out, or API calls return a 500 Cannot read property type error. Cause: Did not enable the data source fallback switch, failed to automatically switch to a backup data source when the primary API encounters an exception, and did not configure reasonable timeout retry mechanisms, leading to task interruption.
- Symptom: When uploading a market data source configuration file via API, the backend service becomes unresponsive or freezes. Cause: Did not adjust the
UPLOAD_FILE_MAX_SIZEparameter to match the actual size of the configuration file. For FastGPT V4.9.7 and later versions, did not synchronously adjustPARSE_FILE_TIMEOUT_SECONDSto extend parsing timeout time, leading to service blocking triggered by parsing timeout after large file uploads.
How to Verify Successful Configuration
- Manually trigger a daily report generation task, check whether the output result includes all configured required fields, and the unit is unified to the preset target unit.
- Simulate an exception in the primary market API, verify that the system automatically switches to the backup data source and generates compliant daily report data.
- View system operation logs, confirm that the data fetch interval matches the configured polling parameters, and there are no records of frequent rate limiting triggers.
- Upload a test configuration file, confirm that the upload process is not blocked, and the configuration items can be loaded and take effect normally.
