Price patterns are often found when price "takes a break," signifying areas of consolidation that can result in a continuation or reversal of the prevailing trend. Trendlines are important in identifying these price patterns that can appear in formations such as flags, pennants and double tops.


Volume plays a role in these patterns, often declining during the pattern's formation, and increasing as price breaks out of the pattern. Technical analysts look for price patterns to forecast future price behavior, including trend continuations and reversals.
