This is a list of chart patterns that shows the performance rank of each formation by
its failure rate. A chart pattern fails if price does not move more than 5% away from the breakout price before
reversing trend (a 20% trend change). A rank of 1 (best) means the chart pattern has the smallest failure rate. N/A
means the chart pattern uses a different
method to gauge performance than the other chart patterns (usually the measure from the breakout to the swing high or
swing low, not to the highest high or lowest low before a trend change). Thus, a performance comparison would be
unfair and meaningless. For more information see
the book Encyclopedia of Chart
Patterns, Second Edition.
