I trade with the trend and look for pullbacks, regressions to the mean to signal a potential trading opportunity. It is when the pullback loses steam and the trend begins to reassert itself that I am prepped for entry. The basis for establishing pullback losing momentum and trend reassetting itself can be determined from any number of technical perspectives or even discretionary ones. I prefer using technical procedures and processes as discretionary trading falls foul, for me, of the Cold-Hot Gap.
