A Rectangle is a continuation pattern that forms as a trading range during a pause in the trend. The pattern is easily identifiable by two comparable highs and two comparable lows. The highs and lows can be connected to form two parallel lines that make up the top and bottom of a rectangle. Rectangles are sometimes referred to as trading ranges, consolidation zones or congestion areas.

There are many similarities between the rectangle and the symmetrical triangle. While both are usually continuation patterns, they can also mark trend significant tops and bottoms. As with the symmetrical triangle, the rectangle pattern is not complete until a breakout has occurred. Sometimes clues can be found, but the direction of the breakout is usually not determinable beforehand.
