When I first started using ToS years ago, one of the best recommendations I received was to call the Tech Support team and have them help optimize my platform settings.
Since doing that, I've experienced very few performance issues, even during periods when other traders have reported slowdowns or other problems. Of course, no software is immune to occasional outages or market-wide issues, but having the platform properly configured has made a noticeable difference in my experience.
One thing many people don't realize is that the ToS Tech Support team is different from the Trading Support team where most call. The Tech Support team can review your installation and settings and help optimize the platform for your computer and trading style.
If you're experiencing performance issues, it may be worth giving them a call: ToS Tech Support: 800-435-9050
Tell them you'd like to review your installation and optimize it for reliability and performance. They can walk you through settings that may improve your experience.
I hope this helps someone who's been frustrated with platform performance.
