In technical analysis, a break on a chart representing a sudden and large price movement accompanied by high trading volume. Generally speaking, charts do not show price gaps because price movements, even when large, occur smoothly enough to not require a break in the chart. Price gaps may occur, for example, when the price of a security suddenly doubles or halves. As with many charting terms, it may be bullish or bearish; a sudden movement upward is a bullish price gap, while a sudden movement downward is bearish. It is also called a breakaway gap.
