After today's update I'm having (again) similar problem with my cTrader desktop - it's consuming much more RAM (over 1GB) and CPU (ca. 8-16%) than usually, which makes it sluggish and even unresponsive for a few seconds. Market orders seem to be going through rather normally, but they are shown on the screen with a few seconds delay (as is sound) and I can't be sure if the delay is in the processing of the order or just in showing the info. Anyway it's not performing well.
First time this happened was around the time this thread was started (after one of the updates). After the next updates issue seemed to be fixed, but now it's back again, and for me it almost makes cTrader unusable for live trading.
I suppose the issue is connected to the way indicators lines are drawn or redrawn, because I use a lot of custom indicators with a lot of lines (mostly WMAs (which calculated on Open of bar, not on close, to prevent unnecessary CPU usage), and overall, rather a lot of formulas in my indicators are re-calculed on each tick.
There are limits to the way I can optimize those indis, so it would be great if you fixed the issue on your side (I've been using the same indicators for over a year or more without an issue).
I can share my indicators if that helps resolve the problem.
I'm gonna paste the link to that thread in troubleshooting window in cTrader.
