Broadening Bottom Pattern Explained
Swings widen at the lows, and the read turns bullish on a break of the upper line.
What it looks like
Swing lows fall while highs hold or drift — volatility expands downward, often late in a decline before a reversal.
Works best with trend and volume context.

How to identify it
- Find a decline where swing lows keep falling while highs hold or drift.
- Draw the two lines: they spread apart like a megaphone.
- Bullish bias often appears after a clean break above the upper line.
When the read is wrong
Invalid if price keeps making new lows with no recovery toward the upper line.
Common mistakes
- Treating each new low as the turn. The pattern is defined by wider swings, and the lows can go on falling.
- Drawing it from too few swings, which turns normal volatility into a pattern.
Questions and answers
