What the data for this category looks like
Market data for the optoelectronics category comes from public market APIs of the Shanghai, Shenzhen, and Beijing Stock Exchanges, plus an industry index constituent stock database. Real-time market data is updated tick-by-tick after market opening each trading day. A full constituent stock daily report document is generated after market close. Each row in the document corresponds to one individual stock, with fields including security code, security abbreviation, daily price change value, daily transaction amount, daily trading volume, latest closing price, and more. Security codes use a 6-digit numeric format. Price change value is measured in yuan. Transaction amount and trading volume use yuan and shares as units respectively.
What constraints these characteristics impose on form and interaction workflows
Data sources come from exchange public APIs, so forms must support filtering data by security code range and exchange sector. Forms must also validate that security codes follow the 6-digit numeric format to prevent invalid inputs. The tick-by-tick real-time market updates and post-market full document generation schedule require forms to configure a data pull time window. Allow real-time pulls only from market opening to one hour after market close on trading days. Call the full document API after market close. The multi-field structure of single documents requires forms to predefine a selectable field list. This avoids parsing failures caused by users entering non-standard fields. The stock data scale for the optoelectronics category is relatively concentrated. The number of items pulled in batches by the form must match the regular document size to avoid loading timeouts.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
form_field_whitelist | ["sec_code", "sec_name", "price_change", "turnover", "volume", "close_price"] | Matches standard fields of optoelectronics market data documents, filters unnecessary parameters |
api_request_interval | 30 seconds | Matches the tick-by-tick update frequency of exchange market data, avoids frequent calls triggering rate limits |
form_batch_limit | 200 items per request | Matches the regular number of entries in a single optoelectronics constituent stock document, avoids loading timeouts |
data_update_deadline | 60 minutes after market close on the same day | Matches the post-market full data generation time window, ensures access to the latest complete data |
field_format_validation | Enabled | Validates that security codes follow the 6-digit numeric format, avoids invalid inputs |
plugin_timeout | 15 seconds | Matches the standard response time of exchange market APIs, avoids request timeouts |
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. Address each case individually, and test against local samples before finalizing.
Three common errors
- Scenario: After importing form configurations exported from version 4.13.0 and above, the original optoelectronics-specific field mappings are lost. Cause: The "Retain custom field mappings" option was not checked during export, or the corresponding category field template was not matched during import.
- Scenario: Calling the form submission interface returns a 429 status code, and the request is rate-limited. Cause: The
api_request_intervalparameter was not set to a reasonable value, and the call frequency exceeded the rate limit threshold of the exchange market API. - Scenario: Voice-activated market queries fail to return accurate optoelectronics individual stock data. Cause: The optoelectronics sector tag was not bound in the voice recognition configuration, so the recognition scope covers the entire market and does not limit results to the targeted sector category.
How to confirm correct configuration
- Submit a test form, enter an optoelectronics security code in 6-digit numeric format, and verify that the returned data includes all preset fields.
- Adjust the
api_request_intervalparameter, simulate multiple requests, and confirm that no rate-limit related errors are triggered. - Export the current form configuration and re-import it, then verify that the field order matches the preset optoelectronics market data fields.
- Enable voice input testing, enter a market query related to optoelectronics, and confirm that returned results are limited to this targeted sector category.
