same risk, huge payoff, and the assumption of price goes into wedge/flags/triangle would come out in the expected direction (as stated in Jack, Schwager's book on TA) gives you the edge?
it's like hitting on a woman, before you speak, you want to see the right signs in a short spread of time..
da longer it takes gives you more doubt, might miss a great ride (better think in the trading context)
ROFL
