Hello,

I am unable to connect to the "Rithmic Direct - DTC" service from Sierra Chart. I consistently receive the following error when attempting to log in:

"Rithmic Direct - DTC | Logon error received from server: permission denied"

I contacted my broker (Apex Trader Funding / Rithmic), and they confirmed that everything is correctly configured and enabled on their end for this account; they referred me to you for further investigation.

Checks already performed on my end:
- No other active Rithmic sessions running simultaneously (R Trader Pro closed and verified via Task Manager before each attempt)
- Rithmic agreements accepted (Market Data Subscription Agreement + Self-Certification Non-Professional)
- R Trader Pro connects normally using the same credentials

My current configuration in Sierra Chart:
- Service: Rithmic Direct - DTC
- Server: Rithmic 01-Chicago Area (tested both Aggregated and Non-Aggregated versions)
- Trading Username / Market Data Username: APEX-658840

Can you help me identify what is blocking the connection? Is there a specific setting to check, or a Sierra Chart-specific configuration step I might have missed?

Thank you in advance for your help.

Best regards,
Angel Quinteros
