Troubleshooting CTP Connectivity and Programmatic Trading Approval Tests

Summary

This account describes connecting VeighNa to CTP before and after new programmatic-trading requirements, with particular attention to error codes 4040 and 4097 and a subsequent testing process. The author recommends a recent VeighNa version and contrasts two futures brokers: one public test account worked through the CTP test interface, while another account produced errors across test and live gateway configurations. Replacing interface DLL files did not resolve the second case.

The practical workaround was to select the test environment on the broker’s CTP gateway; despite an error message, order placement and cancellation reportedly worked. The broker confirmed it could see activity associated with the application ID, enabling testing with Feitai. The described process used programmatic orders, screenshots from Feitai’s tool, review, and an electronic evidence file before the broker’s approval process. This is one user’s broker-specific experience, not a general fix: gateway behavior and approval requirements may differ, and the account supplies no independent verification or performance evidence.

Key ideas

• The author encountered different CTP connection outcomes across two brokers under newer programmatic-trading requirements.
• Replacing the broker-provided interface DLLs did not fix the reported 4040 and 4097 errors.
• A test gateway configuration reportedly allowed orders and cancellations despite an error message.
• The described approval workflow included programmatic test orders, screenshots, evidence collection, and broker review.
• The workaround and process are based on one account and may depend on broker configuration.
