| The Results Snapshot shows the important results of diamond tops and bottoms. In appearance, the only difference between the two diamond patterns is
 the price trend leading to the formation. For diamond tops, the prior price
 trend is upward, whereas diamond bottoms have price trends that lead down to
 the formation.
 The performance of the two types is similar. Both act as reversals of die
 prevailing price trend with a volume trend that diminishes over time. Volume
 on the day of the breakout is also high.
 The failure rate for tops, at 25%, is more than double the rate for bottoms.
 I consider failure rates above 20% to be alarming, so you might consider
 tops unreliable.
 The average decline (21%) and rise (35%) is about what you would expect
 for reversals, with bottoms a bit shy of die usual 40% rise for bullish formations.
 However, the most likely decline for tops is near the average, suggesting
 that there are few large declines to distort the average. Diamond bottoms, with
 a likely rise of just 15%, are well away from the 35% average gain. This suggests
 there are a high number of formations with smaller gains that balance a
 few larger ones.
