The Wave Principle classifies price action as either motive or corrective. Corrective waves move opposite the direction of the primary trend and include the zigzag, flat, triangle and combinations of these patterns. They offer traders an opportunity to rejoin the larger trend. Today, you can watch a lesson from Jeffrey Kennedy's Trader's Classroom in which he teaches you the basics of the triangle, a sideways correction, and shows an example in the chart of Pfizer, Inc. (PFE).
