VeighNa Contract Queries Require a Live Trading Interface
Summary
This forum exchange explains why VeighNa’s contract query may return no data after a manual Mac installation. The key distinction is that contract lookup depends on a connected trading interface, such as CTP or SimNow, rather than on a market-data package such as Tushare.
The suggested troubleshooting steps are to confirm that the interface logged in successfully, run the query from the contract-query screen after connecting, and check account permissions and API compatibility. The post offers operational guidance rather than a backtesting method: it does not describe how to obtain historical data or run a backtest. It also provides no logs or confirmed resolution for the original user’s problem, so the advice should be treated as a checklist rather than a demonstrated fix.
Key ideas
- Contract queries rely on a connected trading interface rather than Tushare data access.
- Confirm successful interface login before attempting a contract query.
- Trigger the lookup from the contract-query screen after connecting.
- Account permissions and API compatibility can also affect query results.
- The exchange does not establish whether these steps resolved the user’s issue.
