What Data for This Category Looks Like
Precious metals-related data is divided into two categories: real-time market data and industry news. Sources include public market APIs from the Shanghai Gold Exchange, the London Bullion Market Association, and compliant industry news platforms. Real-time market data is updated every 10 seconds. Industry research reports for trading days are released within one hour after market close.
Structured market documents include fields such as product identifier, pricing unit, latest transaction price, price change range, trading volume, and more. Unstructured news documents include publisher, publish time, main content, and associated product tags. Domestic pricing uses yuan per gram, international pricing uses US dollars per ounce, and trading volume is measured in kilograms or ounces.
Constraints for Multi-turn Dialogues and Prompt Engineering
High-frequency real-time market updates require multi-turn dialogues to associate the latest timestamp parameter, preventing recall of expired historical data. The mixed format of structured market data and unstructured news requires prompt engineering to clearly distinguish between market query and industry interpretation tasks, and automatically identify user demand types during multi-turn dialogues.
Unique pricing unit differences for precious metals require prompt engineering to either mandate marking the corresponding unit in outputs, or proactively confirm the required pricing method with users at the start of conversations. Differences in product identifiers (such as AU9999, Gold T+D, spot silver, and others) require multi-turn dialogues to gradually clarify the specific product the user refers to, avoiding generation of incorrect marketing content.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | Adapts to the mixed content length of precious metals market data and news, retains sufficient conversation history to track key context such as units and product types |
recallTopK | Top 6–8 results | Structured market data has strong relevance; excessive recall overloads the prompt, while insufficient recall fails to cover the latest multiple market changes |
similarityThreshold | Calibrated via actual testing | Requires precise matching of target precious metal product types to avoid recalling content about other non-ferrous metals; specific value adjusts based on business scenarios |
promptTemplate | Customized per scenario | Must clearly distinguish between market query and news interpretation tasks, mandate marking of pricing units, and include product clarification logic |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Adapts to parsing requirements for large-format precious metals research reports, avoids timeout errors during batch uploads |
UPLOAD_FILE_MAX_SIZE | 200 MB | Covers standard size of single research reports or historical market data sets, adapts to batch content upload scenarios |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, 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 Mistakes
- Phenomenon: When calling MCP to obtain precious metals market images, only part of the K-line or quotation table is displayed. Cause: The prompt did not explicitly require MCP to return complete image size parameters, or did not specify the image ratio suitable for marketing scenarios.
- Phenomenon: After upgrading to version 4.9.13, the end of dialogue return results displays symbols such as
[SOI][EOI]for traceability display rules. Cause: The parameter to disable rule traceability was not configured inpromptTemplate, and the debug output field added after the version update is retained by default. - Phenomenon: After switching precious metal product types multiple times during multi-turn dialogues, the generated marketing content has product confusion. Cause: No product confirmation step was added to the conversation history tracking logic, resulting in loss of the current conversation's product identifier in the context.
How to Verify Proper Configuration
- Initiate multi-turn queries involving different precious metal product types and pricing units, check whether returned content accurately marks units and product types without category confusion.
- Upload a precious metals industry research report, verify that parsed fields are complete with no truncation or format errors.
- View conversation logs to confirm that each MCP call carries the correct timestamp parameter, and no expired data is returned.
- Adjust similarity-related configurations to verify that recall results only cover target precious metal product types, with no content from other non-ferrous metals mixed in.
