My only concern with buying big pullbacks which I like to do is knowing that I am really catching a falling knife regardless of price support, positive divergences, Fib # etc etc. Sometimes all you have done then is buy into a new downtrend that you haven't recognized. Still better than buying breakouts I think but one can argue that buying breakouts is going with the trend. (much like falling on a rising escalator that is going up regardless of your actions and still getting to the top) And buying pullbacks is still catching a falling knife that can cut you to the quick. Tough argument to decide which is best. Depends on the trader's point of view I suppose.
