Why CTP Market Data DLLs Cannot Replace Ronghang APIs Directly

Summary

A forum exchange describes a failed attempt to receive tick data from a Ronghang test interface after replacing its market data DLL with the one used by vn.py’s CTP integration. A participant explains that Ronghang and CTP use incompatible market data servers and APIs, so swapping the DLL alone is insufficient.

The proposed remedy is to rebuild and relink the integration against the appropriate interface. The thread contains no implementation steps, diagnostic details, or confirmation that the rebuild resolved the original issue. It is therefore a narrow integration lesson: a shared underlying market source does not guarantee that two vendors’ APIs or binaries are interchangeable.

Key ideas

  • Replacing a Ronghang market data DLL with a CTP DLL did not produce tick updates.
  • The reply attributes the problem to incompatible servers and APIs.
  • A complete rebuild and relink is suggested, but the thread gives no confirmed resolution.
