The double bottom chart pattern is a technical analysis trading strategy in which the trader attempts to identify a reversal point in the market. Traders look for two consecutive low points separated by an intervening peak, creating a “W” shape on the price chart.

Identifying a Double-Bottom
To identify a Double Bottom chart pattern, look for two distinct lows in the security’s price that form a “W”-shaped pattern. Generally, the pattern should be visible on an intraday and daily chart.
After identifying the two bottoms, look for a confirmation of a trend reversal by watching for a breakout either above the upper resistance line or below the lower support line. If the security price breaks out above the resistance line, it could signal that the security has completed its reversal.
In contrast, a break below the support line could signal a resumption of the downtrend. However, further confirmation of this stock chart pattern should not be relied upon until prices have moved beyond these levels.
Trading a Double Bottom
To trade double-bottom chart patterns, traders should look for a stock that has formed two consecutive low points with an intervening peak. Once the price breaks above the intervening peak neckline, the trader would enter long, with a stop loss set below the neckline. The target can be determined by measuring the height of the lows and setting the target at that distance above the neckline.
Traders should also consider volume when trading a double-bottom chart pattern. Higher volume on the breakout is often considered a confirmation of trend reversal in this setup (see above chart). Traders should be vigilant and wait for higher volumes before entering a trade on any breakout situation.
How Reliable is a Double Bottom Pattern?
A double-bottom stock chart pattern has an 88% success rate on a reversal of an existing downtrend. When the price breaks through resistance, it has an average 50% price increase.
The double bottom occurs when the security price hits the bottom twice, creating a “W”-shaped pattern. This pattern often indicates that the security’s price could soon increase. However, it should be noted that this indicator does not guarantee a reversal in direction.
| Chart Pattern | Success Rate | Average Price Change |
| Double Bottom | 88% | 50% |
Trading Timeframe
Double bottoms can form on any timeframe, from intraday to weekly charts. The most reliable timeframe is on a daily chart that spans multiple months. Intraday timeframes are less reliable because large block trades by institutions can disrupt the pattern.
The Double Bottom pattern typically takes weeks or even months to form. Traders should monitor the stock over a long-term period on a daily chart and be prepared to enter at any time to maximize potential profits.
It can be helpful to use trend lines or other technical indicators, such as moving averages or RSI, to identify the double bottom pattern.
Entry and Exit Points
The entry point for a Double Bottom pattern is at the break of resistance after the second bottom. Traders should place a stop-loss order below the lower low to protect against potential losses. The exit point can be determined by placing an initial target near the resistance level/neckline and then trailing stops behind it until the trend reverses.
It is also important to remember that double bottoms can fail at a rate of 11%, and traders should always have an exit strategy in case of a failed pattern. Furthermore, managing risk during any trade is essential, as the potential for loss is still real. Using proper risk management techniques, traders can maximize profits while limiting losses.
What Happens After Double Bottom Pattern?
Two decades of research by Tom Bulkowski show that after a double bottom pattern is confirmed on a break of the neckline at a higher volume, the price increase averages +50%.
Once the double bottom pattern is confirmed, traders should consider opening a long position near the support area and placing a stop-loss order below the lower low. This will help them better manage their risk as they enter a potential trade.
What Happens with a Failed Double Bottom Pattern?
A double bottom in a bull market fails 12% of the time. When a double-bottom pattern fails, the stock price falls below the support area and continues to decline. This can be used as an opportunity for traders to short-sell or place stop-loss orders at the support level. Proper risk management is essential when attempting to capitalize on failed patterns to limit losses.

Double Bottom Pattern Breakout
When the double bottom is successful, the price breaks out of the support area and continues to rise. This can create a great opportunity for traders to capitalize on the potential gains while limiting losses by placing a stop-loss order above the lower high.
A Double Bottom Uptrend
The double bottom can also form within an existing uptrend. This is usually a sign of strength and often results in the continuation of the uptrend. Traders should be aware that this pattern may provide false signals, as it does not guarantee that the trend will continue, and prices could reverse at any time.
Measuring the Price Target
If the distance from the trough to the neckline is 8%, the logical price target should be 8% above the neckline. It is calculated by adding the pattern’s height to the breakout point. This gives traders a good indication of where to expect prices to move following a successful breakout. Once the double bottom breakout is confirmed, traders should set their stop-loss order below the neckline.
In the chart above, you can see the height/depth of the double bottom is equal to the price target.
