What is Double Bottom?

A Double Bottom is a bullish reversal pattern where price tests a low twice, bounces in between, then breaks above the neckline. The endpoint returns both lows, the intervening high, the neckline and a projected target.

Limitations: Geometric pattern detection depends on pivot settings, so tune deviationATR and depth or lookback values on your own market. A confirmed pattern is not a guaranteed move. Nothing on this page is financial advice.
