Channels are part of the pattern strategy but will be explained separately because of its specific requirements. • It begins a trend reversal if successful or becomes a continuation pattern if invalidated. E.g. link1, link2, link3 • Points ABCD make an harmonic pattern and point C is the minimum target for this and at point C the decision to successfully breakout of invalidate is made • Identify a channel first then, the ABCD harmonic pattern within it. • After point D is made, it must maintain its trendline to be successful or else it invalidates and goes lower.
