What the Data for This Category Looks Like
Precious metal market and yield data comes primarily from official interfaces of compliant on-exchange trading markets and third-party compliant market data sources. Data updates at high frequency during trading hours. Only settlement-related data updates outside trading hours. Standard data documents include core fields such as product identifier, name, latest transaction price, settlement price, price change amount, and position volume. Field units vary by product segment. Gold uses grams as the pricing unit. Silver uses kilograms. Yield-related fields use basis points as the unit. Most document formats use standardized JSON structures.
Constraints Imposed on Forms and Interactions
The multi-data-source nature, unit differences, and high-frequency updates of precious metal categories impose multiple constraints on forms and interactions. First, add data source filter options to the form to distinguish real-time on-exchange market data and after-hours settlement data. This prevents calls to invalid data sources. Second, build in automatic unit adaptation logic. The logic automatically converts and displays pricing units based on the selected precious metal subcategory, without requiring manual user adjustment. High-frequency market data requires configuring form pull intervals to avoid exceeding interface call limits. At the same time, distinguish fields for real-time transaction prices and settlement prices. Clearly mark field purposes during interactions to prevent errors in yield calculations.
How to Configure the Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
form_unit_auto_adapt | Enabled | Precious metals have multiple pricing units such as grams and kilograms; automatic adaptation reduces user input verification costs |
allowed_data_sources | ["shfe_gold", "lbma_silver", "shfe_palladium"] | Restrict compliant precious metal market data sources to avoid calls to unauthorized interfaces |
data_fetch_interval | 15–25 seconds | Balance the timeliness of precious metal real-time market data and the risk of interface call rate limiting |
form_field_filter | Display grouped by precious metal subcategory | There are many precious metal subcategories; grouped display simplifies form structure |
input_validate_trigger | on_blur | Trigger unit conversion verification when the user leaves the input field to avoid interaction lag caused by real-time verification |
api_request_timeout | 8 seconds | Precious metal market data interfaces respond quickly; this duration covers most normal requests |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material forms, data volume, and business rules. Specific issues require individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Symptom: An error
Cannot convert undefined or null to objectappears when running the workflow. Cause: No allowed data sources are configured, and the market data interface returns empty data, causing form-bound fields to fail to obtain valid values. - Symptom: Unable to perform conditional branch selection based on AI-generated precious metal yield results. Cause: Fields output by the AI are not mapped to the form's conditional judgment input items, causing branch logic to fail to trigger.
- Symptom: Pricing units are displayed incorrectly in the form. Cause: The
form_unit_auto_adaptconfiguration is not enabled, and unit display is not automatically adjusted based on the selected precious metal subcategory, causing a mismatch between user input and system verification rules.
How to Confirm Proper Configuration
- Manually switch the precious metal subcategory options in the form, and verify that the pricing unit automatically adapts to the standard unit of the corresponding category.
- Call the configured market data source interface, and verify that the returned core fields can be correctly bound to the form's input items.
- Trigger an AI conversation to generate results related to precious metal yields, and verify that these results can be used as input parameters for subsequent workflow nodes.
- Simulate high-frequency form submission requests, and observe whether interface rate limit errors are triggered to confirm that the pull interval configuration is reasonable.
