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.
Double Bottom formula
| Output | Calculation |
|---|---|
| Neckline | High between the two lows |
| Target | Neckline + (neckline − lows) |
How to read Double Bottom in your code
| Signal | Meaning | Condition |
|---|---|---|
| Forming or confirmed | Detection status | status and is_confirmed |
| Breakout | Price closed above the neckline | breakout_occurred is true |
| Target | Measured-move projection | projection_price |
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.
