This page scores descending scallop chart patterns. Patterns with scores above 0 show gains averaging 34% (upward breakouts) and declines averaging 21% (downward breakouts). Scores below 0 show gains of 10% and declines of 10%. High scores do not guarantee good performance, nor does a low score mean you found a stinker.
