                The only error we are seeing is the following in SierraChart02: UDPListener (1508). Port 22904 | Error binding to UDP port: 22904.  Windows error code 10048: Only one usage of each socket address (protocol/network address/port) is normally permitted. 
Unless you are specifically doing work with UDP, you can ignore this. But, if you want to resolve it, then in the SierraChart02 instance, go to Global Settings >> Sierra Chart Server Settings and change the entry for UDP Port to a value other than 22904. Some other items of note for SierraChart01: - The following indicates a problem with the study sst_volume_dots: Error loading: D:\Documents\SierraChart01\Data\sst_volume_dots.dll. File not found or may be missing SCDLLName line. - This instance has the Current Selected Service set to SC Data - All Services, but the symbols are for the Sierra Chart Order Routing Service. Open your Chartbooks in that instance and select Edit >> Translate Symbols to Current Service in order to change the symbols to the correct ones. For the most reliable, advanced, and zero cost futures order routing, use the Teton service:  Sierra Chart Teton Futures Order Routing  |
