A double bottom pattern is a technical analysis charting formation that signifies a significant change in a market trend, typically indicating a shift from a bearish (downward) trend to a bullish (upward) trend. This pattern is characterized by two distinct lows at approximately the same price level, separated by a peak.
Structure of a Double Bottom Pattern
In a double bottom pattern, the price movement of a security forms the following stages:
- First Bottom: The price decreases to a low point, marking the first bottom.
- Peak or Rally: After reaching the first bottom, the price rises to a peak or resistance level, often representing a short-term reversal or rally.
- Second Bottom: The price declines again, forming the second bottom at roughly the same level as the first bottom.
- Confirmation: Upon reaching the second bottom, the price rises again, breaking through the peak or resistance level set in the previous rally.
The breakout above the peak confirms the double bottom pattern and suggests a trend reversal.
Identifying Double Bottom Patterns
Volume Considerations
Volume trends are crucial in confirming double bottom patterns. Ideally, higher trading volumes accompany the peaks and breakouts, indicating strong market interest and further validating the pattern.
Time Frame
The time frame between the two bottoms can vary, ranging from a few weeks to several months. Longer time frames generally indicate a stronger and more reliable pattern.
Example of a Double Bottom Pattern
Consider a stock that has been experiencing a downward trend. Over three months, the price drops from $150 to $100 (first bottom), then rallies to $120 (peak), falls back to $100 (second bottom), and finally breaks out above $120, indicating a potential upward movement.

Historical Context and Importance
Double bottom patterns have been used by traders and analysts for decades. Their reliability in predicting trend reversals has made them a staple in technical analysis. Notable examples include the long-term double bottom formations seen during major market recoveries, such as after the dot-com crash in the early 2000s.
Applicability in Trading and Investment
Trading Strategies
- Entry Point: Traders often enter long positions when the price breaks above the peak after the second bottom.
- Stop-Loss Orders: Set just below the second bottom to minimize potential losses in case the pattern fails.
- Target Price: The distance from the bottoms to the peak can be projected upwards from the breakout point to estimate potential profit targets.
Comparison with Other Patterns
Double Top Pattern
A double top pattern is the inverse of the double bottom pattern, indicating a trend reversal from up to down. It consists of two peaks at approximately the same level, separated by a trough, and signifies a potential bearish trend after the breakdown below the trough level.
Head and Shoulders Pattern
Another reversal pattern, the head and shoulders pattern, involves three peaks: a central higher peak (head) flanked by two lower peaks (shoulders). A breakdown below the trough connecting the shoulders confirms the pattern and indicates a bearish reversal.
Related Terms
- Bullish Divergence: A situation where the price forms lower lows, but an indicator (e.g., RSI) forms higher lows, often preceding a bullish reversal.
- Support Level: A price level where a downward trend can be expected to pause due to a concentration of demand.
