Hello, I am currently unable to connect Sierra Chart to my Rithmic account. The error message is: “Connection error message from service: Rithmic Direct - DTC | Logon error received from server: permission denied.” The important point is that this issue is occurring on both Sierra Chart versions: the standard Windows version, which was working correctly until recently; the ARM version, which I also tested separately. I have already performed the following checks: Completely shut down Sierra Chart, Windows, and Parallels before retrying. Made sure only one Sierra Chart instance was running. Manually deleted and re-entered my Rithmic Trading Username and Password, without copy/paste. Confirmed that Market Data Username/Password and Historical Data Username/Password are blank. I am using Rithmic Direct - DTC [trading]. Server selected: LucidTrading-Chicago Area-Non-Aggregated. I have already signed all required Rithmic agreements/documents and I do not currently see any new agreement pending. The same Rithmic account and Sierra Chart configuration were working correctly before this issue started. I have also opened a support ticket with Lucid Trading so they can verify the account permissions/entitlements on the Rithmic side. Could you please confirm whether there is anything on the Sierra Chart side that could cause this specific “permission denied” response, or whether this message indicates that the connection is being rejected directly by the Rithmic server/account permissions? If useful, I can also provide the Message Log / Trade Service Log and screenshots of my Data/Trade Service Settings. Thank you. |
