Profiles to scale
If this is checked, multiple profile panels in the same window will be correctly scaled on the price axis. However, if you are looking at profiles from different periods of time, the prices may be very different, making it difficult to see them side by side. TPA provides both a menu item and a toolbar button for making all of the profiles in a window snap to the top of the window for easy viewing and vice versa. If you want the default to be profiles all lined up at the top of the window (not to scale) then uncheck this box.
