What the data for this category looks like
Minor metal data primarily originates from domestic industry associations, commodity exchanges, and international terminal platforms. The Minor Metal Branch of the China Nonferrous Metals Industry Association and designated delivery warehouses of the Shanghai Futures Exchange release domestic data. International data comes from London Metal Exchange minor metal contract quotes and Bloomberg commodity terminal sections. Spot data updates daily after market close. Futures data pushes in real time during trading hours. Industry statistical data updates once weekly. Each data entry includes product code, product name, quote type, latest transaction price, daily highest/lowest transaction price, daily trading volume, and statistical cycle. Units cover standard classifications for specific product categories such as yuan/ton, kg/piece.
What constraints do these characteristics impose on model access and configuration
The multi-source nature, varied update frequencies, and multiple field characteristics of minor metal data impose multiple constraints on model access configuration. Differences exist in field naming across different data sources, which must be uniformly mapped to a format recognizable by the model to avoid input confusion. The large gap between update cycles of real-time pushed futures data and daily updated spot data requires configuring differentiated synchronization scheduling rules to ensure data timeliness. The coverage of multiple product categories requires configuring precise filtering rules to retain only yield-related data for target categories, reducing redundant information that interferes with model output. Differences in access permissions across data sources must also be included in the configuration to meet access requirements for domestic and international data sources.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
dataSourceType | Hybrid mode (real-time pull + scheduled synchronization) | Adapts to the different update rhythms of minor metal spot daily updates and futures real-time fluctuations |
dataSyncInterval | 300 seconds (spot data sources), 60 seconds (futures data sources) | Matches the update frequency of daily spot updates and real-time futures price movements |
fieldFilterRule | Retain only product name, latest transaction price, daily fluctuation range, and statistical cycle | Focuses on core fields required for yield calculation, reducing redundant model input |
modelCallTrigger | Triggered by data update events | Ensures model calls are synchronized with minor metal price updates, avoiding outdated data |
multiSourceMapping | Calibrated through actual testing | Unifies field naming differences across data sources, for example, mapping LME’s "LME Price" to the model-required "latest_price" |
maxResponseLength | 800-1200 characters | Minor metal yield broadcast content includes multi-product data, requiring output length control to adapt to conversation scenarios |
The parameter values provided on this page are common recommended starting points for defining configurations. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to conduct tests on your own samples before finalizing settings.
Three common mistakes
- Phenomenon: Traces such as
[SOI]/[EOI]appear at the end of model conversation response results. Cause: The parameter to disable rule display is not configured insystemPrompt, and version 4.9.13 enables call rule trace output by default. - Phenomenon: The large language model does not call the MCP tool as expected to retrieve minor metal data. Cause:
toolCallPriorityis not configured as high priority, and the prompt does not explicitly specify calling the minor metal data source tool. - Phenomenon: Minor metal data synchronization times out, with status code
504 Gateway Timeoutreturned. Cause: ThedataSyncTimeoutconfiguration value is too small, failing to adapt to response delays from some overseas data sources such as LME.
How to confirm the configuration is complete
- View the data source synchronization log, verify that the most recent synchronization time matches the update rhythm of the minor metal data source, and adjust the synchronization interval until expectations are met.
- Initiate a test call, check that the model response content only includes the configured core fields with no redundant data items.
- Trigger a data update event, verify that the model automatically calls the tool to retrieve the latest minor metal data with no delays or omissions.
- Check the system prompt and multimodal configuration, confirm that rule trace output is not enabled, there are no extra symbols at the end of response results, and version v4.9.0 and above supports video recognition functionality.
