I was having major problems with TradeStation.  It was slow, lagging, the matrices were not cable of taking trade orders sometime.  Because I had heard and read so many terrible reports, the problem must be on the version that I was using.  Well, being a computer illiterate, I started to try and learn what was with this box I have on my desk.  The major problem was that I was using OneDrive to save and transfer files.  This is a big no no!!!  OneDrive was saving all my TrafdeStation Desktops and Workspaces.  I got rid of OneDrive  and it helped a bit more.  I was ready to go down to what Kevin is using.  It would be much work to do all the charts.  I read more about what might be causing this lag and crashing.  I did some research and found that I had many corrupt Desktops and Workspaces.  It's a lengthy process but not as lengthy as redoing everything as you would have to do to go back down to the Basic Version.  I look at all the charts that weren't loading properly and the Desktops that seemed to lag and deleted them.  The MultiWalk website has good directions to save Desktop and Workspace foolders, rename them, and save them.  I then deleted TradeStation completely and started it up again taking time to make sure I wasn't loading back corrupted charts, workspaces or desktops.  Since then, I have had no problems with crashing and everything has been running smoothly.  My Excel sheets are clean and in the correct format.  There are two things that I do regularly.  One, which Kevin suggests is to delete the cache.  I do this every weekend.  There is something else that I do quite often.  This is to clear the computer of junk.  I am using Version:  10.00.09.1405 Update 85
