Model Integration and Configuration for Coking Coal Yield

What This Category's Data Looks Like

Coking coal market and yield data originates primarily from public sources including the Dalian Commodity Exchange futures market API and commodity industry information platforms. Full daily reports are generated after each trading day closes. No updates are made on non-trading days. Documents use structured table format, with fields including contract code, delivery month, daily settlement price, daily closing price, spot benchmark price, open interest, and trading volume. Price fields use yuan/ton as their unit. Trading volume and open interest use lots as their unit. No additional percentage-based statistical fields are included.

Constraints Imposed on Model Integration and Configuration Workflows

Public data source APIs have call frequency limits. A reasonable pull interval must be configured to avoid triggering rate limiting. The daily update feature requires scheduled tasks to run only on trading days. Logic to skip non-trading days must be implemented. The structured table format requires enabling a dedicated parsing switch to avoid field extraction errors from generic text parsing. The unique units and contract identifiers require configuring entity recognition rules and field mappings. This ensures the model outputs information in a unified format compatible with subsequent broadcast logic.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`PARSE_STRUCTURED_DATA`	Enabled	Coking coal market data uses standardized structured tables. Enabling this switch automatically extracts field values and avoids errors from generic text parsing
`schedule_cron`	`0 18 * * 1-5`	Aligns with the Dalian Commodity Exchange's schedule, where daily market data is published after 18:00 on trading days. Triggers pull tasks only on weekdays
`api_request_timeout`	`30 seconds`	Public data source APIs respond quickly. Setting a 30-second timeout avoids unnecessary waiting and supports high-frequency data pull requirements
`entity_recognition_rules`	Match contract codes starting with JM followed by 1-2 digits	Coking coal futures contracts use JM as a standard prefix. This rule accurately filters irrelevant data from other categories
`field_mapping_config`	Map "settlement price" to `settle_price`, "closing price" to `close_price`, and "trading volume" to `volume`	Standardized field names ensure parameter consistency during model calls and support downstream broadcast logic
`rag_top_k`	`Top 3`	Daily coking coal market data volume is small. Retrieving 3 entries covers core market information and avoids redundant content interfering with broadcasts

The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Each scenario requires specific analysis. It is recommended to test on your own samples before finalizing settings.

Three Common Configuration Mistakes

Issue: Embedded market broadcast components via iframe fail to load on mini-program platforms. The console returns a 403 Forbidden error. Cause: Only web-side cross-domain whitelists were configured. No valid domain names for mini-program platforms were added, causing domain verification to fail.
Issue: Calls to voice broadcast models return a model not found error. Voice content cannot be generated normally. Cause: The official access path for the model was not confirmed. The request address for a generic voice model was mistakenly used for the coking coal-specific broadcast interface.
Issue: Knowledge base question and answer recall result counts differ between API models and locally deployed models. Cause: The rag_top_k parameter was not unified. Locally deployed models automatically adjust recall counts due to context window limits, which do not match the configuration for API models.

How to Confirm Configuration Is Complete

Call the data pull API to check if returned structured data fields fully match the configured field_mapping_config.
Trigger the scheduled task to confirm that the latest data is automatically pulled at the specified time on trading days, with no pull actions on non-trading days.
Test model calls to check if broadcast output contains correct fields and units for coking coal contracts, with no formatting issues.
Check cross-domain configurations. No CORS or 403 related errors appear when loading components on mini-program platforms.
