Diagnosing a Missing Interactive Brokers API in VeighNa

Article vn.py community
Read the original

Summary

This forum post reports that VeighNa 4.3.0 fails to launch its trader after the user selects a trading interface and application module. The traceback shows the startup process importing the VeighNa Interactive Brokers gateway, which then fails because Python cannot find the `ibapi` module. The report helps identify the failure point: the gateway dependency is missing from the environment used by VeighNa Studio.

The post does not give a fix or confirm whether the issue was resolved. It also does not establish why the dependency is absent, whether installation or environment configuration caused it, or whether other versions behave differently. Treat it as a useful error signature for troubleshooting, rather than a complete installation guide.

Key ideas

  • The reported launch failure occurs while importing the Interactive Brokers gateway.
  • The traceback identifies the missing `ibapi` module as the immediate cause.
  • The post provides an error report but does not document a resolution.
