Double Bottom: Price Reversal Patterns in Technical Analysis

In this guide to understanding the Double Bottom charting pattern, we’ll show you what this chart looks like and how to interpret it.

What Is the Double Bottom Pattern?

The Double Bottom technical analysis charting pattern is a common and highly effective price reversal pattern.

Chart 1 below of the Dow-Mini future illustrates the Double Bottom reversal pattern:

To create a double bottom pattern, price begins in a downtrend, stops, and then reverses trend. However, the reversal to the upside is short-term.

The price breaks again to the downside only to stop again and reverse direction upwards. With the second bottom of the double bottom pattern, it is usually more bullish if the second low is higher than the first low.

How to Interpret the Double Bottom Chart

The pattern gives a potential buy signal when price breaks the confirmation line to the upside. The confirmation line is drawn across the top of the double bottom pattern (see Chart 1 above).

Retracement

Often, after price penetrates the confirmation line, price will retrace for a short time, sometimes back to the confirmation line. This retracement offers a second chance to get into the market long.

Volume

Volume also plays an important part of interpreting the Double Bottom pattern; this is illustrated in Chart 2 below of Pfizer (PFE):

Generally, volume should explode when the confirmation line is penetrated as it did in the chart of Pfizer (PFE).
