What data for securities financing daily reports looks like
Securities financing daily report data originates primarily from two sources: official disclosures from the Shanghai and Shenzhen Stock Exchanges, and internal business reports from securities firms. Updates are generated after daily market close, and released on the next trading day (T+1). Common document formats are Excel and PDF. Some organizations organize content as web pages or collaborative documents. Core fields include statistical date, market name, financing balance, financing purchase amount, securities lending sale volume, securities lending remaining volume, and additional related fields. Units include hundreds of millions of yuan, ten thousand shares, and similar units. Some documents split detailed content by sector or individual stock. Full-market detailed documents covering all stocks contain a large number of entries.
What constraints do these characteristics impose on document parsing and chunking
Daily updated structured data requires parsing tools to adapt to fixed table structures, preventing cross-page tables from being split into unrelated chunks. The binding of fields and their corresponding units requires chunking to retain that association, without splitting fields and units across different chunks. The large volume of individual stock detailed entries in full-market data requires chunking to group content by sector or individual stock, avoiding overly cluttered single chunks that reduce retrieval quality. Differences in format across data sources require parsing rules to support Excel, PDF, web pages, and other formats. Rules must also accommodate minor format variations between official disclosures and organization-created documents.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_TABLE_STRATEGY | "Structured First" mode | The core content of securities financing daily reports is structured tables. Prioritize preserving row and column structures to avoid losing field-unit associations during text-based parsing |
maxChunkSize | 800–1200 characters | Each chunk can hold 15-20 individual stock detailed records. This balances contextual relevance and retrieval precision |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Full-market individual stock detailed Excel files have large data volumes. Reserve sufficient time to complete parsing |
PARSE_EXCEL_SHEET_INDEX | 0 | Most organizations place valid data in the first worksheet of their financing daily report Excel files. This avoids parsing invalid worksheets |
ENABLE_CHUNK_GROUPING | Enabled | Group chunks by sector or individual stock. This improves retrieval relevance for content in the same category |
ALLOWED_PARSE_DOMAINS | Official stock exchange domains, internal compliant data source domains | Filter non-compliant data sources to ensure the authority and validity of parsed content |
The parameter values provided on this page are common starting points for configuration setup. Actual values are affected by material format, data volume, and business rules. Specific scenarios require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Issues
- Scenario: Parsing a Yuque public link returns an unsupported format error and empty fields. Cause: The Yuque domain is not added to the
ALLOWED_PARSE_DOMAINSwhitelist, and web parsing adaptation rules are not enabled. - Scenario: Calling an HTTP tool shows successful parameter parsing, but the tool does not execute and returns a 403 status code. Cause: The whitelist domain for tool calls is not configured, or required authentication parameters are missing from the request header.
- Scenario: An imported PDF financing daily report cannot be previewed in search results. Cause: The
ENABLE_FILE_PREVIEWparameter is not enabled, or associated information from the original PDF pages is not retained during parsing.
How to Confirm Correct Configuration
- Upload a standard-format securities financing daily report file. Verify that the parsed chunk content retains the field and unit associations from the original table.
- Add the domain of the test data source to
ALLOWED_PARSE_DOMAINS. Attempt to parse the corresponding link or file, and confirm the task completes normally without errors. - After configuring tool call-related parameters, run a test request. Confirm the tool trigger logic works correctly.
- Import a PDF-format financing daily report. Verify that the parsed content can be previewed normally in search results.
