Optimizing chart responsiveness

I have been using Sierra Chart with complete fluidity. Looking for a broader overview, more clarity and better visibility of past levels of support/resistance, I reduced my quantity of charts while expanding their size. Essentially now: one screen = one chart. I notice the responsiveness of each chart has decreased, which makes perfect sense. To judge the responsiveness of a chart, I rely on Chart Settings -> Performance -> Chart Drawing Time in Milliseconds. If I zoom in on a 5" chart, a shorter timeframe of data is now on display therefore the chart becomes 1.5x ~ 2x more responsive in milliseconds. If I zoom out, the chart becomes increasingly unresponsive. A maximized 60" chart is more stable. Despite being fullscreen and showing up to 20 previous days, it stays ~ as fluid whether zoomed in or not. I suppose this is because each 60" bar contains less detail, less data, less underlying complexity. Question: I would like to obtain the same behavior from my 5" chart. My 5" chart is fullscreen so it displays up to 6 days back. I only need the 5" chart to "know" the full complexity of data (level 2 data, tick by tick, etc...) for the current day. Is there a way to trim down the complexity of the data "known" by the chart for the past days in order to improve its performance? In other words, barebones green and red bars. No studies are present except a basic moving average and volume. My second question regards PC specs. I have: - Processor : AMD Ryzen Threadripper 1950X 16-Core Processor, 3400 Mhz, 16 Cores, 32 logical processors - Two simultaneous graphics cards : NVIDIA GeForce GTX 1060 6B + NVIDIA GeForce GTX1080 - 32 GB of RAM I have one main instance of Sierra and three sub-instances to spread out the load. I only consume 5% CPU, 25% memory when trading stocks at the market open. In priority, what part of my PC should I want to upgrade in order to get faster reaction times on my charts? How much of an impact does the speed of my SSD hard drive have here? In the current situation, I have other programs installed on the SSD. Your documentation mentions it is preferable to only have Sierra Chart installed on the SSD. I am going to do this. Would you recommend simply deleting other programs/folders manually or formatting altogether? As long as no other program is running from the same SSD anymore, no matter what method used, it should be right? I'm also considering buying an NVME SSD. How relevant do you think this would be with this concern in mind, for faster chart responsiveness? Date Time Of Last Edit: 2025-03-04 18:10:46

Oh, don't worry too much. I found out activating Open GL on my charts made them more responsive to begin with, so I no longer worry about them beeing zoomed it or out anymore. They're fast whatever the situation. The way to trim down the complexity of the data known by a chart for the past days in order to improve its performance is via compressing its file data. Sierra Chart has a feature for this. Date Time Of Last Edit: 2025-03-12 15:30:24
