Post From: Very bad performance for VbP Study when extending POCs

Hi, I noticed a strange performance issue today: I have a 30 minute candlestick chart (ES). It's an intraday chart that shows 365 days. The only study on this chart is a Volume by Price study. I configured it to show a profile for each candle (e.g. "Volume Graph Period Type = Multiple Profiles Based on Fixed Time" and "Fixed Time = 30 Minutes"). Everything runs smoothly as long as I do not activate the option to extend the POCs in the VbP study. However, as soon as I enable the option "Extend Point of Control" and set it to "Until Future Intersection" Sierra Chart becomes virtually unusable. I can barely scroll any of my charts anymore, and everything is very laggy and delayed (including the dialogs & settings windows, e.g. it takes almost 5 seconds after pressing F6 until the chart study settings dialog opens). I experimented with the settings and it seems the only way to fix this is to either deactivate the extension of the POCs in the VbP study, delete the VbP study (hiding it is not enough) or reduce the loaded days in the chart signficantly from 365 to e.g. 14 days. I am even more surprised because I checked CPU and memory usage in the Windows task manager and my computer would have more than enough free resources, so the performance view in the Windows task manager doesn't give a clue to why Sierra Chart is struggling so much here. Seems to be neither the CPU nor the memory (CPU usage is only at 8 %, memory at 35 %). Is it a "known issue" that the performance of the VbP is so terrible with the POCs extended (although it's running on a very strong computer)? Is there any reasonable way to optimize this (other than to significantly reduce the number of loaded days)? |
