Hello gentlemen, As context, I'm trying to achieve a setup of running three Sierra instances, each with two chartbooks open, of which each chartbook has a dozen charts of various types (footprint, depth histogram, renko, candlestick, volume profile, etc.), and each chart running between five and fifteen studies. It's a lot to ask I know. For what it's worth the PC is a new build with an Ultra 7 CPU and nothing else running on it. That said, a few questions about reducing lag and maximizing performance: - When Market Depth Data Days To Load is set to 0 both globally and on a specific chart, but the chart includes a study that uses depth, does the chart only load and processs depth data starting from the moment it is opened, but not load or process depth data before that moment? (And if so, that would imply that any depth-dependent lookback study would only work after the chart has been opened long enough to receive depth data to match the lookback period?) - If a chart does not need depth data but it continues to load when the chart is opened (maybe happens because a chart had a depth study like bid/ask depth bars, the study was removed, depth data still loads), what can I do to make it stop loading? - Is there a maximum update interval in Chart Settings > Display > Chart Update Interval and/or will it accept something big like 30000 for 30 seconds, that I can use for clunkier charts that don't need updates even at the second level, or even 3600000 to update hourly something more long-term like a daily or weekly TPO? - Is there any way to keep charts in a chartbook but somehow tell them not to update or calculate studies until they're called upon to do so? Or is that best accomplished by moving those charts to a separate chartbook and opening that chartbook as needed? I know your time is valuable so don't expect anything in depth but any other quick tips to free up CPU cycles and maximize performance are greatly appreciated, beyond removing unused studies and grouping as many important studies into the fewest amount of high-refresh charts as possible. Thanks as always for your help and your awesome software. Date Time Of Last Edit: 2026-03-02 15:23:50

- When Market Depth Data Days To Load is set to 0 both globally and on a specific chart, but the chart includes a study that uses depth, does the chart only load and processs depth data starting from the moment it is opened, but not load or process depth data before that moment? (And if so, that would imply that any depth-dependent lookback study would only work after the chart has been opened long enough to receive depth data to match the lookback period?)
When you open a chart the Market Depth data is going to be loaded for that chart. There is no loading of any data prior to a chart being opened. As such, if you are wanting to access historical market depth data from a chart, then that chart must be open and must have the data fully loaded. - If a chart does not need depth data but it continues to load when the chart is opened (maybe happens because a chart had a depth study like bid/ask depth bars, the study was removed, depth data still loads), what can I do to make it stop loading?
If the Market Depth data is loading for a chart, then there is some reason for it to be doing so. You would have to look at what item is causing it to be loaded. Keep in mind the market depth loading will show as a loading message with the file for the market depth that is being loaded at that time, so it will show with a file extension of .depth. The .scid files are the normal data files, so these will always load. - Is there a maximum update interval in Chart Settings > Display > Chart Update Interval and/or will it accept something big like 30000 for 30 seconds, that I can use for clunkier charts that don't need updates even at the second level, or even 3600000 to update hourly something more long-term like a daily or weekly TPO?
The maximum value is 1200000. - Is there any way to keep charts in a chartbook but somehow tell them not to update or calculate studies until they're called upon to do so? Or is that best accomplished by moving those charts to a separate chartbook and opening that chartbook as needed?
There is no way to do this. The only option is to set the "Chart Update Interval" to a very large number. I know your time is valuable so don't expect anything in depth but any other quick tips to free up CPU cycles and maximize performance are greatly appreciated
