Description
A double bottom is a bullish reversal chart pattern that forms when price tests a support level twice and fails to break lower on both attempts. The pattern resembles the letter “W” and is commonly seen after strong bearish trends.
Between the two lows, price creates a temporary rally which forms the neckline resistance level. The pattern is generally considered complete once price breaks above this neckline resistance.
Psychology Behind It
The first bottom forms as sellers remain in control and continue pushing price lower. After rejection from support, buyers temporarily gain strength and push price higher.
Sellers then attempt another breakdown and retest the lows, but fail to generate enough momentum to continue the downtrend. This second rejection often signals weakening bearish momentum and increasing buyer pressure.
Once price breaks above the neckline resistance, many traders interpret this as confirmation that buyers have gained control, increasing the probability of an upside move.
Confirmation Signals
- Strong bullish candle breaking above the neckline
- Increase in trading volume during breakout
- RSI bullish divergence
- Weak momentum on the second low
- Failure to create a lower low
- Retest and hold of the neckline after breakout
Pattern Completion Trigger
A double bottom pattern is generally considered confirmed once price closes above the neckline resistance level connecting the high between the two lows.
Many traders wait for either a strong breakout candle or a neckline retest hold before entering a long position.
Weaknesses & Invalidations
- Weak volume during the neckline breakout
- Price quickly falls back below the neckline after breakout
- Second bottom breaks significantly below the first low
- Pattern forms during extremely strong bearish conditions
- No bullish follow-through after confirmation
If price breaks below the second low after confirmation, the bullish setup may be invalidated.
Best Location To Find It
- Major support zones
- After strong sell-offs or impulsive bearish moves
- Near cycle lows or local lows
- At higher timeframe support levels
- During exhaustion phases in bearish trends
Measured Move / Target Projection
Traders often estimate the upside target by measuring the distance between the lows and the neckline, then projecting that same distance upward from the breakout point.
This measured move acts as a guideline rather than a guaranteed target and should be combined with resistance levels and overall market structure.
Example Trade Use
Traders may look for long opportunities once price breaks above the neckline with strong bullish momentum and increased volume. Some traders wait for a retest of the neckline support before entering to improve risk-to-reward.
Stops are commonly placed below the second low while targets are often aimed at the measured move projection or nearby resistance zones.
Risk Management Notes
Double bottom patterns should not be traded in isolation. Volume, trend strength, market structure, and confirmation all influence the quality of the setup.
False breakouts can occur frequently, especially in volatile markets, so traders should always define invalidation levels and manage position sizing appropriately.
