A pennant is formed in a similar way to a triangle. The key difference is that the upper border of the pennant is directed downwards, the lower one is upwards. Usually the pattern appears after strong impulsive movements in the direction of the main trend.


bull pennant


A bullish pennant resembles a symmetrical triangle. Typically, a bullish pennant continues the current bullish trend. After breaking through the upper boundary of the pennant, a price movement equal to the size of the pennant is possible.

It is recommended to trade in the direction of the pattern breakout - if the price closes above the resistance line - buy, if the price closes below the support line - sell. The purpose of working out is the value of the base of the pattern (H) in points.

Descending triangle

"Descending Triangle" - a pattern of continuation of the downward trend. Formed between a horizontal support level and a descending resistance line. After closing the price below the support level, sales are recommended, the target of working out is the value of the pattern base (H) in points.
