Quote from Piffle:
Also, we need to be clear on what it means when rules "work". Work means they have a positive expectation, not that they make every trade profitable. There is no set of rules that makes every trade profitable. One of the biggest problems losing (heck and even some winning) traders have is that they don't embrace expectation and how it works and focus too much on the current trade, IMO.
quality gem. copy on a post-it note and keep pasted in front of evolving trader's screen.
