What this category of data looks like
Industrial metal market data primarily comes from official public APIs of global commodity exchanges and compliant third-party commodity data service platforms. Full daily report data updates are completed shortly after each trading day closes. Intraday real-time quotes are pushed on a minute-by-minute basis. Data documents mostly use standardized JSON or CSV formats, including fields such as contract code, product name, daily settlement price, total daily trading volume, total open positions, and price change value. Price units are yuan/ton or USD/ton. Trading volume and open position units are trading lots.
What constraints do these characteristics impose on the model access and configuration link
Industrial metal data sources are scattered, with minor format differences across sources. This requires configuring multi-data source adaptation rules during access, to support connecting interfaces from different exchanges and completing field mapping. The scheduled update requirement for daily report broadcasts demands configuring trigger rules that match exchange closing time windows, to avoid pulling outdated unupdated data. Different industrial metal products have varying contract field naming conventions. This requires configuring custom field mapping parameters to align unified indicators from different data sources into standard fields recognizable by the model. The large number of product types requires configuring product filtering rules, to only pull market data for target industrial metals and reduce interference from redundant information on model processing.
How to set the configuration
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
DATA_SOURCE_TYPE | multi_source | Adapts to market data from multiple exchanges for industrial metals |
CRON_EXPRESSION | 0 15 20 * * 1-5 | Matches the closing update window at 20:15 on domestic commodity trading days, ensuring latest daily report data is pulled |
FIELD_MAPPING_RULE | Custom field mapping | Aligns differing field names across exchanges, unifies standard indicators recognizable by the model |
RECALL_FIELD_COUNT | 6 | Focuses on core market indicators, reduces interference from redundant fields on model processing |
PARSE_STRUCTURED_DATA | Enabled | Industrial metal data uses standardized structured formats; enabling this improves parsing and call efficiency |
DATA_FILTER_CONDITION | product in ["copper", "aluminum", "zinc"] | Only pulls market data for target industrial metal products, filters irrelevant information |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material forms, data volume and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three common errors
- Symptom: Returns
401 Unauthorizederror when calling the workflow, or the interface prompts that the API Key is invalid. Cause: Uses a globally universal API Key to directly call the application conversation interface, without using the dedicated API Key for the corresponding workflow application. - Symptom: Workflow call fails, returns the prompt "corresponding workflow not found". Cause: Fails to fill in the unique identification ID of the workflow, or fills in the ID incorrectly, failing to match the deployed workflow instance.
- Symptom: Industrial metal market indicator recognition or classification results have large deviations. Cause: Fails to adjust model parameters for professional fields and data characteristics of industrial metals, uses a general classification model without enabling domain adaptation configuration.
How to confirm the configuration is successful
- Manually trigger a data pull task, verify that returned fields align with the configured mapping rules, and confirm only market data for target industrial metal products is included.
- View scheduled task execution logs, confirm the task successfully triggers and completes data pull within the preset window after the trading day closes, with no abnormal errors.
- Initiate a model call test, check that the generated daily report content covers the configured core indicators, with no redundant information from irrelevant product categories.
- Verify API Key call permissions, confirm the used key has access permissions for the corresponding workflow, and can complete interface requests normally.
