Hello, I am trying to export Market Depth data using the Sierra Chart DTC protocol with a python script. However, "Separate subscription for market depth updates not supported." I'm getting error. In the settings section, the "Use Separate Connection for Market By Order Data" section is recorded as "NO". I subscribe to Denali depth data and Sierra Chart "10" features. Is the problem in transferring this data a technical code error? Or is subscription "10" not enough to export market depth data? Here are the log records of the error I received: 2025-02-12 09:41:06.676 | DTC Protocol server | Incoming connection from 127.0.0.1. 2025-02-12 09:41:06.677 | DTC client #2. 127.0.0.1 (2) | Creating socket. 2025-02-12 09:41:06.677 | DTC client #2. 127.0.0.1 (2) | New receive buffer size: 262144 2025-02-12 09:41:06.677 | DTC client #2. 127.0.0.1 (2) | Allocated send buffers: 32 of 131072 bytes. 2025-02-12 09:41:06.678 | DTC client #2. 127.0.0.1 | Set DTC encoding to JSON 2025-02-12 09:41:06.681 | DTC client #2. 127.0.0.1 | Requested heartbeat interval: 5 2025-02-12 09:41:06.681 | DTC client #2. hello. 127.0.0.1 | Received logon request. 2025-02-12 09:41:06.681 | DTC client #2. hello. 127.0.0.1 | Sent successful Logon response message to client.
