Troubleshooting CTP Connection Errors by Checking API and Broker Version Compatibility

Article vn.py community
Read the original

Summary

This brief forum exchange addresses an error in which the exchange server appears disconnected during a CTP penetration test, even though the configured address seems correct. A respondent identifies a possible cause: the API version and the broker's trading counter version may not match. The practical lesson is to check version compatibility when endpoint configuration alone does not explain a connection failure.

The discussion is very limited. It does not specify the versions involved, provide diagnostic steps, explain how to change versions, or confirm that the mismatch resolved the original report. The suggestion is therefore a troubleshooting lead rather than a complete procedure, and other causes of a failed connection are not considered. It concerns trading-system connectivity, not a trading strategy or market analysis.

Key ideas

  • A reported CTP test shows an exchange-server disconnection despite an apparently correct address.
  • The reply points to a possible mismatch between API and broker counter versions.
  • The forum does not provide version details or verify the proposed diagnosis.
