Bullish — W◐ Heuristic
◆ The PatternTwo troughs at the same level — the "W" formation
The Double Bottom is the bullish mirror of the double top — price tests support twice and bounces. The "W" shape forms with a peak between two troughs. Breakout above the neckline (the middle peak) confirms the reversal.
Target = Neckline + (Neckline − Trough)
A "spring" — where the second bottom slightly undercuts the first before reversing — can be especially powerful.
// Double Bottom — W formation
Key insight: The strongest double bottoms have increasing volume on the second bounce — it shows buyers stepping in more aggressively at the support level.
Pattern bridge: Two bounces off the same floor mirror activation floors in neural nets.
