Quote from Johnny Rotten:
Anyone with half a brain should be able to look at Tuesday's action and say to themselves: a great day to have NOT traded! If you have a method that kept you out of the market on Tuesday then you did a great job. It's as simple as that. But if you insist on trying to "master" such shit days and make money from them, then you are trading for ego not for money. You just become a fool with no discipline or patience.
I'm copying this here to emphasize it. It's just the sort of thing that many who have been here for a while would endorse.
