I have MS 10.1 EOD, I don’t think 11 is any different. Your right, It’s not a trading platform.
It does have a scanning module “The Explorer” and a System back-tester. The system tester is fine but limited in functionality. It will tell you what the results of a system would have been in the past.
I haven’t noticed a ‘simulation’ mode. But, you can look at your indicators /system daily and track ‘trades’ you would have made in a spreadsheet program.
