Is Current Selected Service in a File >> New Instance sub-instance permanently locked to DTC - Sub Instance and not changeable via the GUI
Yes. Sub-instances started by selecting "File >> New Instance" are always tied to the main instance and thus have the "Current Selected Service" set to "DTC - Sub Instance". There is not a way to change the way a sub-instance is setup to do what you are wanting. We first want to point out that if the sub-instance has the option for "Trade >> Trade Simulation Mode On" enabled, then that sub-instance is only working in Simulation Mode locally. So no orders are going to the Main Instance, everything is contained within that sub-instance. If the above is not what you want, and you really want to have another instance of Sierra Chart connected to "SC Data", then you need to have a separate "Installation" of Sierra Chart (not started using File >> New Instance). A separate installation is completely independent from other Sierra Chart installations/instances. Refer to the following: Using Multiple Data and Trading Services at the Same Time: Step-By-Step Instructions to Install Multiple Copies of Sierra Chart If you plan on using Sub-Instances in this separate installation, then be sure to note that you need to change the port numbers. Refer to the following: Using DTC Server for Data and Trading in Another Sierra Chart Instance: Resolving DTC Protocol Server Port Number Conflicts For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing |
