I highly disagree to this one because even you can answer these questions with confidence it doesnt give you the guarantee to be a professional trader.Yeah, you can answer it out but

pretty sure that when you are already in the actual situation those things you have said will surely change.Experience is what the most important most of the time - you know theories

or even common sense kind of questions but if you do lack this then its still a problem compared if you do have the experience which you can actually know on what to do next.
