Trading from theory can only lead to theoretical profits. That is why paper trader's love to use all the complicated crap to show how "universal" or "cosmic" the markets are.....bull Trading (when you get there) is very simple set of rules. It is the the guy who can execute that will make and save and prevent losses. An old gunfighter once said "I was never the fastest or loudest or smartest.....but when the time came, I always pulled the trigger when it needed too be pulled"
