These are improper symbols. There are no symbols in Sierra Chart that have the word "GLOBEX" at the end. You need to change these symbols to what they should be (most likely "-CME").

F.US.SR3U23 and F.US.SR3Z24 is a CQG symbol, but you are connected to Interactive Brokers.


2026-01-06 09:21:23.767 | Error loading: C:\SierraChart TEST FESX ONLY\Data\sst_volume_profile.dll. File not found or may be missing SCDLLName line.

There is a problem with this DLL file and it can not be loaded. You need to talk to the developer and get it corrected.


2026-01-06 09:21:24.083 | sst_volume_dots.dll is not 64-bit
2026-01-06 09:21:24.156 | sst_volume_dots_2151.dll is not 64-bit
2026-01-06 09:21:26.099 | TicinoMathV3.0.dll is not 64-bit
2026-01-06 09:21:26.236 | TicinoMathV3.0_2151.dll is not 64-bit



You are not using the 64-bit version of these studies and you need to be since you are on a 64-bit system. You would need to get the updated versions from the developer, or remove them from your system.


2026-01-06 09:21:29.035 | Circular chart reference detected. Charts: 5, 2. Chartbook: FESX 13-05-24.Cht.
2026-01-06 09:21:36.548 | Circular chart reference detected. Charts: 2, 5. Chartbook: FESX 13-05-24.Cht.
2026-01-06 09:21:37.420 | Circular chart reference detected. Charts: 5, 2. Chartbook: FESX 13-05-24.Cht.

This is quite likely what is causing you the issue. Refer to the following:
High CPU Usage | Inactive User Interface | Poor Performance | Long Time to Load Chart Data | Charts Reloading Often: 30.9 References to Other Charts / Continuous Full Recalculation of Charts

There are also numerous mentions of charts recalculating due to being tagged, which means that there is a reference to another chart (most likely a Study/Price Overlay). These could also create Circular References that the software did not find. So you would need to look through your charts.

As it states, you are not authorized to use this study, so you should not have it on any charts.



2026-01-06 09:30:25.167 | Message from IB: Market data farm connection is inactive but should be available upon demand.usfuture.il. IB Error Code: 2108. Request ID: -1. | Number times message added: 1

This indicates some kind of issue with the connection to Interactive Brokers. This could also be a reason for the system not updating, as when it loses connection to the trading service, the data stops as well.

We do not have any insight as why there is an issue or what exactly these errors indicate. You would need to discuss with Interactive Brokers.

Another set of messages from IB indicating some issue with connectivity.

From here there was a reconnection to the data feed and the issues repeat.
