1) There are different parts in successful trading/investing. One of them is trade identification/analysis. While there might be other parts such as position sizing, trade management, psychology, one should be as consistent as possible while dealing with each part.
2) When identifying chart patterns consistency is key. There is a tendency to see patterns when actually they don't exist. A good way to avoid this is to focus on successful chart pattern completions and keep on looking for similar setups.
3) I.e. H&S bottom reversal should form after a downtrend. Preferably the chart pattern should have a horizontal neckline and symmetry between the right and left shoulder. Breakout should clear not only the neckline but also the 200-day average. 
4) Different examples that show consistency in identification of H&S bottom reversal.
