What Is A Double Bottom Chart Pattern?

In technical analysis, a double bottom pattern, also known as a "double bottom reversal pattern", is a bullish price reversal chart pattern that forms on the price charts of financial markets when the market forms two prominent swing low support levels or troughs and then the price reverses from a bearish trend to a bullish trend. The pattern is confirmed when the price breaks out above the resistance level, also known as the "neckline", of the pattern.

The double bottom pattern is shaped like the letter "W" on a price chart.

Double Bottom Pattern Components

Double Bottom Pattern Components

In order to identify a double bottom pattern, there are three components required.

The three components of a double bottom pattern are:

  • A swing low support level on the left: This is the first swing low level of the double bottom pattern that forms on the left side of the pattern. It is marked "1" on the chart above. It is the first of the two bottoms of the double bottom pattern.
  • A swing low support level on the right: This is the second swing low level of the double bottom pattern that forms on the right side of the pattern. The low is at the same price area as the first swing low price. It is marked "2" on the chart.
  • A neckline resistance level: The resistance level or the neckline of the pattern is the swing high level before the push into the support level. It is marked "neckline" on the chart above.

Drawing a double bottom pattern requires marking all these three components on the price charts of a market where the pattern forms.

In the 3-minute price chart of EUR/GBP, a double bottom pattern forms at the end of a short-term bearish trend.

It leads to a bullish reversal in the price of the currency pair and a fast move higher once it breaks out above the resistance (neckline) level.

This illustrates that double bottoms can form and work in lower timeframe price charts.

Example Of A Double Bottom Pattern On A Higher Timeframe Price Chart

Double bottom on higher timeframe chart

In the weekly price chart of Apple stock, a double bottom pattern forms at the end of a bearish trend.

The price of Apple stock reverses and breaks out from the pattern and this leads to a multi-year bullish trend in the market.

This illustrates that double bottoms can form and work in higher timeframe price charts.
