Pennant patterns, or flags, are created after an asset experiences a period of upward movement, followed by a consolidation. Generally, there will be a significant increase during the early stages of the trend, before it enters into a series of smaller upward and downward movements.
Pennants can be either bullish or bearish, and they can represent a continuation or a reversal. The above chart is an example of a bullish continuation. In this respect, pennants can be a form of bilateral pattern because they show either continuations or reversals.
While a pennant may seem similar to a wedge pattern or a triangle pattern – explained in the next sections – it is important to note that wedges are narrower than pennants or triangles. Also, wedges differ from pennants because a wedge is always ascending or descending, while a pennant is always horizontal.
