What the data for this category looks like
Energy metal market and yield data is sourced from domestic commodity futures exchanges, spot trading platforms, and industry inventory databases. Two update schedules are used:
- Daily summary data is updated within 1 hour after the close of each trading day
- Intraday market data refreshes every 5 minutes
Data is provided in structured JSON or CSV format, with fields including trade date, product identifier, settlement price, price change percentage, spot benchmark price, total inventory, and more. Unit specifications:
- Price: yuan per ton
- Price change: percentage
- Position volume: lots
- Inventory: tons
Constraints Imposed on Workflow Orchestration
Decentralized data sources require configuration of multiple parallel pull nodes, plus a field alignment node to unify formats across different sources. Fixed update schedules require precise execution times for scheduled trigger nodes, to avoid invalid calls outside trading hours. Structured data with multiple fields requires a field filter node to retain only core yield and market fields, reducing processing overhead. Merging futures and spot data across sources requires setting joint primary key matching rules, to prevent merge failures caused by differing field order. Daily report broadcasting requires aggregation of multi-source data, so an aggregation node must be configured to organize the final dataset.
Configuration Settings
| Configuration Item | Recommended Value | Basis for Selection |
|---|---|---|
trigger_type | Scheduled trigger, execution time set to 17:30 daily | Matches the standard data update schedule of 1 hour after energy metal trading market close |
parallel_data_nodes | 2-3 parallel pull nodes | Covers the three core data sources: futures market, spot quotes, and industry inventory |
field_filter_list | Retain trade_date, product_code, settle_price, change_rate, spot_price fields | Only retain core business fields required for daily report broadcasting, reducing subsequent data processing volume |
merge_match_key | Use trade_date and product_code as joint primary keys | Ensures accurate matching of market and spot data across sources |
node_timeout | 600 seconds | Allows sufficient time for multi-source data pulling and format conversion |
error_retry_times | 2 retries | Addresses call failures caused by temporary fluctuations in individual data sources |
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. Specific issues require targeted analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Symptom: A 504 Gateway Timeout status code is returned immediately after entering the tool call phase following a query. Cause: No reasonable timeout threshold is set, and multi-source parallel pulling exceeds the node's allowable response time.
- Symptom: Configured global variables do not take effect, and core fields are empty in the broadcast content. Cause: Default values for global variables are not initialized in the workflow startup node, and variables are referenced before assignment is complete.
- Symptom: Variables referenced in the workflow cannot be correctly rendered in the main body of the broadcast content. Cause: The platform-specified variable reference syntax is not used, or the variable scope does not cover the current broadcast node.
How to Confirm Proper Configuration
- Check the execution time of the scheduled trigger node to confirm it matches the energy metal data update schedule.
- Run a test workflow to verify that the pulled data fields match the preset filter list.
- Pass simulated energy metal data to confirm that variable references are correctly rendered in the broadcast main body.
- Check the workflow execution logs to confirm that no timeout or merge failure records appear in multi-source data pull nodes.
