Technical analysis: Example of a Double Bottom

Technical analysis: Example of a Double Bottom

In technical analysis, a decline in the price of a stock is followed by a comeback and then a drop back to the original drop level. The pattern resembles the letter W.

This pattern is considered a positive for the stock in technical analysis. The stock has bottomed out, and technical analysts expect it to rise in the future.

What is a Double bottom pattern?

Double-bottom patterns are the inverse of double-top patterns. The conclusions drawn from this pattern are diametrically opposed.

A single rounding bottom is followed by a double bottom, which can be the first sign of a possible change in direction. Rounding bottom patterns are most common at the end of a long bearish trend. 

When there are two rounded bottoms in a row, this can be a sign that investors are watching the asset to make money off of its last drop toward a support level.

A double bottom usually means that the market is about to turn up, so investors can profit from a bullish rally. Common trading strategies following a double bottom include long positions that profit from rising security prices.

A Double Bottom Example

In the case that Advanced Micro Devices is in a general downtrend, the above daily trading chart shows a double bottom (AMD). After a sudden, sharp drop, there is a lot of buying interest at the first low.

This creates a long, light candlestick and a bullish engulfing line, which are both bullish reversal patterns based on candlestick analysis. The next high is almost 10% higher than the first low.

Since most bounces from the first low are between 10% and 20%, investors should be looking for another move down at this time.

The pattern's second low is within 3% to 4% of the first, strengthening it. Since solid support has been achieved and challenged twice, traders could expect a pullback upward or a fresh uptrend now that the double bottom is in place.

The pattern breaks when the price falls below the double-bottom lows, indicating a probable decline. A daily closing above the intermediate high indicates a major change and maybe a new uptrend.

When detected correctly, double-bottom formations are quite effective. They can, however, be exceedingly harmful if they are misinterpreted. As a result, before leaping to conclusions, one must exercise the utmost caution and patience.

The most important example is a second bottom around the previous low, followed by confirmation of bullish trend days or weeks later. These patterns are most noticeable on daily and weekly charts.

Identify A Double- Bottom Pattern

A step-by-step tutorial on spotting the double bottom pattern on a chart:

  • Determine the two separate bottoms that are identical in width and height.
  • The distance between the bottoms should not be too close - this will depend on the time frame.
  • Confirm the neckline/price level of resistance
  • Other technical indicators, like moving averages and oscillators, can be used to support double-bottom bullish indications.
  • Try to avoid trading against strong trends.

Importance of Double Bottom

A double-bottom is an indicator of positive signals since the stock has achieved its low, and the second bottom is usually followed by a continuing climb in the stock price.

How is Trading Performed During a Double Bottom?

A double-bottom reversal, as previously indicated, is a bullish movement in stock prices. There are two lessons in it. Looking at Diagram 1, we can see that the initial low occurs after a bearish movement in stock prices, followed by a bullish movement to hit the neckline.

The following event is the second low, which is then followed by a bullish movement. In order to form a double bottom, the second bullish movement that follows the first bullish movement needs to be more important than the first.

Traders who trade during the double bottom typically go long during the second low, anticipating a bullish surge.


Double bottoms are one of the most important chart patterns for figuring out long-term trends because they show that a key low has been reached for the foreseeable future.

After the second low, the pattern usually predicts a 10% to 20% bounce back, but there may be more upside if the fundamentals have changed in favor of the securities.

For example, a strong forecast for future earnings could spark a new rise. Visually spotting double bottoms requires reasonably long-term charts. The lows should be 3% to 4% apart.

The first bounce back's 10% highs set the minimum objective threshold for potential growth. If the new bottom is within 3% to 4% of the previous low, the pattern is considered to have been completed by a retreat and the second test of downward support.

Following the formation of a double-bottom pattern, investors should anticipate upward momentum. If the high that marks the middle of the pattern is broken after the second bottom, this indicates that there is additional upside potential and maybe the beginning of a new uptrend.
