I can only agree with the answers but here is a technical answer. Bob showed us a picture with price changing trend every 6.6 weeks (just an example) on average. To me that means the later I enter the trend the less chance I have to win or win big with small lots assuming I play from line to line or for longer term. The issue here is that I enter when the indicators show a nice trend but in fact it is time for price to turn around or just rest and do some ranging before deciding which way to go. Both can be dangerous and disheartening. This is why I use 10.2 as a filter and go for the short term with it. Others, who have more time for trading or more experience can catch the trend early.
