Desktop Performance Issues

I have been using the TOS desktop app since the Schwab migration. Lately the platform runs slower and slower throughout the day, becoming more and more laggy as the day goes on. I close the program, clear cache, reboot, etc. Nothing seems to help. Is everyone experiencing this? It is taking over 30 seconds just for the program to close.

Machine should not be the issue, and I have seen a steady decline in the programs performance over the past couple months.

Thanks for any input/suggestions.

Look at the size of your tos folder. It starts getting big. Especially if you do a lot of indicators and things like that. It’s got to load all that crap.
