VeighNa Market Data Subscriptions and Contract Queries
Summary
This forum exchange concerns configuring a Huaxin Qidian stock simulation connection in VeighNa and diagnosing why a strategy cannot retrieve some market data. The user reports connecting successfully and seeing securities quotes in the main interface, but later encounters missing data when running a strategy. Replies distinguish the market data API used for subscriptions from the trading API used to query contract information.
That distinction helps explain why a symbol may appear in the interface without appearing in contract-query results or being available through the same strategy workflow. The discussion also notes that individual stock codes work for the user while index codes do not. It does not establish whether index subscriptions are supported, provide configuration steps, or resolve the index-data issue; it is a brief troubleshooting exchange rather than a complete integration guide.
Key ideas
- Market data subscriptions and contract information queries use different APIs.
- Seeing quotes in the main interface does not by itself confirm that a strategy can access the same data.
- The user reports that stock codes work in a strategy while index codes do not.
- The discussion does not confirm whether index data is supported or explain how to configure it.
