Pennants are very similar to symmetrical triangles except that they generally occur over a shorter time frame and tend to be asymmetrical, although they don't have to be. They also offer more of a bias to continue in the underlying direction than triangles and can be recognised by their squat or squashed corrective nature. They are often best distinguished by the presence of a pole, a vertical move to which the pennant attaches itself.

Construction is effected by drawing a resistance line sloping down across the tops of the corrective price bars, generally starting at the recent high. The lower side of the pennant is drawn as a straight line across the bottoms of the corrective price bars.

Pennant in an up trend

In the example below the underlying trend is to higher prices. There is, therefore, a greater probability for price to break out of the pennant to the high side. Nevertheless a break down from the pennant would have also generated a valid signal, but a signal to sell.

Pennant in a down trend

Pennants will sometimes only consist of the minimum number of bars in the correction, as in the example below. In this case, the pole is formed as a result of a break down from a congestion area higher. The underlying direction to lower prices provides a most probable direction for the break down from the pennant under formation.

Construction is required at the first sign of a retracement to the predominant direction. Three or four bars is the minimum requirement and will generally yield at least the start of a pennant, if not a complete pennant as in the example below. However the pennant could change shape and form into a more complex triangle or flag shape.

A down market pennant is more likely to produce a break down to lower prices, than a break out to higher prices.
