strategies like this are very profitable ,Bearish Pennants Similar to rectangles, pennants are continuation patterns formed after strong moves.
After a big upward or downward move, buyers or sellers usually pause to catch their breath before taking the pair further in the same direction. Because of this, the price usually consolidates and forms a tiny symmetrical triangle, which is called a pennant.
While the price is still consolidating, more buyers or sellers usually decide to jump in on the strong move, forcing the price to bust out of the pennant formation.
