What Data for This Category Looks Like
Iron ore futures market data is sourced primarily from the official market interface of the Dalian Commodity Exchange. Full daily data updates are completed within one hour after market close on trading days. No updates occur on non-trading days. Each daily market report includes these fields: contract code, product name, previous settlement price, closing price on the day, price change, open interest, and trading volume. Price-related fields use yuan/ton as the unit. Price change uses yuan as the unit. Open interest and trading volume use lots as the unit. Contract codes always start with the uppercase letter I, followed by four digits to identify the delivery month.
Constraints Imposed by These Characteristics on Tool Calling and Plugins
The exclusive data source for iron ore market data requires tool calling to connect to the official compliant interface of the Dalian Commodity Exchange. Avoid using unauthorized data sources to prevent distorted data. The daily update schedule on trading days requires scheduled tool calling triggers to be limited to the period after market close on trading days. This avoids sending invalid requests. The special field units and formats require the plugin’s parameter parsing module to pre-configure mappings for units such as yuan/ton and lots. It also requires validation of the I-prefixed contract code format to prevent requesting incorrect contract data. When calling multiple contracts in parallel, split requests into batches per contract. This avoids overloading a single request and triggering interface rate limits.
Recommended Configuration Parameters
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
tool_request_timeout | 30 seconds | Dalian Commodity Exchange interface responses typically take 10-20 seconds. Add buffer time to avoid timeout interruptions |
tool_cache_ttl | 86400 seconds | Iron ore market data updates once per day. Match the cache duration to the update cycle to avoid repeated requests |
plugin_param_schema | Required contract code field, format: I+four digits (e.g. I2409). Optional field: trading date | Match the naming rules and data query parameter requirements for Dalian Commodity Exchange iron ore contracts |
max_parallel_tools | 2 | Single contract request load is moderate. Too many parallel requests may trigger exchange interface rate limits |
error_retry_count | 2 | Address occasional network fluctuations or temporary interface jitter. Too many retries may trigger rate limits |
tool_auth_type | API_KEY authentication | Dalian Commodity Exchange market interfaces require official assigned API_KEY for identity verification, which meets compliance requirements |
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. Analyze specific issues on a case-by-case basis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Symptom: Tool calls return the
aiPointsNotEnougherror code. Cause: No tool calling point quota is configured, or the quota has been exhausted, which cannot support the current request. - Symptom: After an iron ore market XLSX file is uploaded, AI conversations based on the file content cannot be started. Cause: The
PARSE_FILE_AUTO_EXTRACTparameter is not enabled, or the field order of market data in the file does not match the preset mapping. - Symptom: No valid results are generated when a multimodal plugin is called to create iron ore market analysis content. Cause: The
multimodal_tool_data_sourceparameter is not configured correctly, or a valid iron ore contract code parameter is not specified.
How to Verify Proper Configuration
- Initiate a tool calling request. Check whether returned results include preset iron ore market fields to confirm normal parameter parsing.
- Review tool calling logs to confirm request triggers occur within the specified period after market close on trading days, with no invalid request records.
- Verify cache configuration effectiveness. Confirm cache hit logs match the
tool_cache_ttlconfiguration duration. - Trigger a test scenario simulating interface failure. Confirm the system retries according to the
error_retry_countconfiguration, and resumes normal requests after retries.
