congestion - Investment & Finance Definition
An area on a pricing chart that indicates where previous heavy trading volume occurred or an area in which closing prices on successive trading days tended to cluster. Congestion often looks like a rectangle on a price chart, as prices have remained in a narrow range. Usually, when prices break out of the range they resume the price direction that prices had before entering the area of congestion.
