When trading, I monitor 4 different futures at the same time with the corresponding cash times. My question: What is best for optimal data processing, opening 4 individual instances or opening 4 chart books in the main instance at the same time? Thank You very much. I read the manual but it wasn't clear to me. |

The benefits of having multiple instances are that each one can run on different cores in your CPU and you can view all chartbooks at the same time. The main drawback to using multiple instances is that more RAM is used. When 100% of memory is used, the OS must swap pages of virtual memory in and out to disk, which adds delays. With sufficient RAM you can improve performance using multiple instances.

So you are telling me to run faster, I must open more instances (chart books)? Really, my 24 cores need 24 instances? Thanks |

No you don't need 24 instances for your 24 cores. Since you monitor 4 markets, you can use 4 instances or less. It depends of the workload of your 4 chartbooks. Open your Task Manager => Performance Tab, right clic on the graph => Change graph to => Logical Processors, and check on which core runs Sierra Chart (on my screenshot, it is the first one, core 0) Ideally, this core workload should not exceed 50-60% of its maximum during rest time because during high market activity (like during the NY open) it can rise 10-30%. You don't want your core to be overloaded because it can cause latency. My rule of thumb is when my core is loaded to more than 60%, it is usually time to create a new instance and to distribute the workload. When using multiple instances, there are a few drawbacks like : - If you do a Market Replay, you can't have a perfect sync between instances. - Some shortcuts like Recenter Trade DOM Scales don't work across instances.
