A double bottom pattern is a bullish reversal chart pattern that forms after a decline. Price falls to a low, rebounds, falls back to roughly the same level, then rallies again. The result looks like the letter “W.” The two lows mark a support level that held twice, and the pattern is confirmed only when price closes above the peak between them. Until that close, the shape is a possible double bottom and nothing more.

What Is a Double Bottom?

The double bottom (also called a W bottom or W pattern) is a classical reversal pattern. It signals that a downtrend may be ending and that buyers have started to absorb selling at a particular price.

The pattern has four parts:

1. A prior downtrend. A double bottom needs a decline to reverse. Two similar lows inside a sideways range are just a range.
2. The first low. Selling exhausts itself and price bounces.
3. The intermediate high. The bounce stalls and price turns down again. This peak is often called the neckline or pivot high, and it becomes the confirmation level.
4. The second low. Price returns to the area of the first low, finds support again, and turns higher.

The double bottom breakout is the close above the intermediate high that completes the pattern. A drop below the lows instead cancels the setup and suggests the downtrend has resumed.

How a Double Bottom Pattern Works

The buyer and seller story

The pattern describes a contest between sellers and buyers. Sellers drive the downtrend to a first low, where buying (including short covering) produces a bounce that is still read as a correction, so sellers usually try again. This time the earlier low holds, which suggests selling pressure has weakened or the outlook has changed. Traders who shorted the second decline now hold positions near support, and a move back above the intermediate high can force them to cover, adding to the rally.

Is a double bottom bullish?

Yes, once confirmed. It suggests an important low is in place and that price may retrace higher, possibly starting a new uptrend. Before the breakout, the second low is only a retest of support, and support tested twice can still break on the third attempt.

Timeframe and spacing of the lows

The pattern is generally treated as an intermediate to longer term formation, so daily and weekly charts are the standard place to look for it. The more time separates the two lows, the more meaningful the pattern: lows weeks or months apart reflect a broader shift in supply and demand than two dips a few bars apart.

Day traders use the same structure on intraday charts, but short timeframes produce many more W shapes, and many are noise. A pattern on a 5 minute chart carries the weight of a 5 minute chart, not a weekly one.

Volume confirmation

Volume is watched closely during formation. In the textbook version, volume expands on the two rallies: the bounce from the first low and the push from the second low toward the neckline. A clear rise in volume as price breaks the intermediate high adds weight to the signal. A breakout on thin volume is easier to reverse.

Spot forex has no centralized exchange volume. Forex charts usually show tick volume, the number of price changes in a period. It is widely used as a proxy for activity, but it does not report traded amounts.

Fundamental confirmation

Stock traders often look for a reason behind the reversal, such as improving earnings expectations, sector strength or a firmer broad market. A double bottom that lines up with better fundamentals is more convincing than one that appears while the company’s outlook is still deteriorating. For currency pairs, the equivalent is a change in the macro picture, such as a shift in rate expectations between the two economies.

How to Trade a Double Bottom Pattern

The classical approach uses three levels taken straight from the pattern.

Entry. The standard entry is a long position on a daily close above the intermediate high. Waiting for the close rather than an intraday poke filters out some failed breakouts. Some traders wait for a pullback to retest the broken neckline as support, which gives a better price but misses moves that do not pull back.

Stop loss. The usual stop sits below the second low. If price breaks that level, the pattern is invalid. Many traders place the stop a little beyond the low rather than exactly on it, often using a volatility measure such as the Average True Range to size that buffer.

Target. Measure the height of the pattern: the distance from the lows to the intermediate high. Add that distance to the breakout level for the minimum target. A more aggressive target uses twice the height.

In formula form:

• Pattern height = intermediate high − low of the pattern
• Minimum target = intermediate high + pattern height
• Aggressive target = intermediate high + (2 × pattern height)

Some traders look at entries before the breakout, often called an early pivot point entry, by buying as price lifts off the second low. This gets a much tighter stop but trades on an unconfirmed pattern.

Example of a Double Bottom Pattern

Hypothetical example for illustration only.

A stock falls from $70 to a first low of $50.00. It rebounds to an intermediate high of $55.00, a 10% bounce, then slides back to a second low of $50.80, which is 1.6% above the first low. Volume rises on the push from the second low, and the stock closes at $55.20, above the neckline.

• Pattern height: $55.00 − $50.00 = $5.00
• Minimum target: $55.00 + $5.00 = $60.00
• Aggressive target: $55.00 + $10.00 = $65.00
• Entry at the breakout close: $55.20
• Stop just below the second low: $50.70

Risk per share is $55.20 − $50.70 = $4.50. Reward to the minimum target is $60.00 − $55.20 = $4.80, only about 1.07 to 1. This is structural: with entry at the top of the pattern and the stop at the bottom, risk on a confirmed entry is close to the full pattern height, and the minimum target offers roughly the same distance. The trade improves only if price runs past the minimum target, the stop is tightened (for example, on a neckline retest), or the entry comes earlier at the cost of confirmation.

With $10,000 in the account and a 1% risk limit ($100), the position would be about 22 shares ($100 ÷ $4.50). The position size calculator runs the same arithmetic for currency pairs, where lot size and pip value enter the calculation.

Must the Two Lows Be the Same?

No. The lows only need to be close. A frequently cited guideline is that the second low should fall within about 3% to 4% of the first.

A slightly higher second low is often read favorably: sellers gave up before reaching the prior low, which suggests demand arrived earlier. A slightly lower second low that quickly recovers can resemble a bear trap, where a brief break of support shakes out sellers before the reversal. If the second low breaks well below the first and stays there, the pattern has failed.

Lows that land at an identical price do occur, and they make that level stand out as a defined support zone.

Types of Double Bottom Patterns

Analysts classify double bottoms by the shape of each low:

• Adam and Adam: both lows are sharp, narrow V shaped spikes.
• Eve and Eve: both lows are wide, rounded troughs formed over more bars.
• Adam and Eve: a sharp first low followed by a rounded second low.
• Eve and Adam: a rounded first low followed by a sharp second low.

The trading rules are the same for all four. The labels help traders describe the pattern consistently and compare results across their own records.

Patterns Often Confused With a Double Bottom

The last row matters in practice. Many traders check whether the RSI or MACD makes a higher low while price makes an equal or lower low. That divergence suggests downside momentum faded on the second test. It supports the double bottom reading without replacing the breakout requirement.

Limitations of a Double Bottom Pattern

Identification is subjective. Two traders can look at the same chart and disagree about whether the lows are close enough, whether the prior decline was large enough, or which peak is the neckline. Automated scanners apply fixed rules, but someone chose those rules.

Many W shapes never confirm. Price can stall below the neckline and roll over into a third, lower low.

Breakouts fail. A close above the neckline can reverse back into the range, especially on light volume or in a market still dominated by a strong downtrend on a higher timeframe.

Targets are reference points, not forecasts. The measured move describes a level that classical analysis associates with the pattern. It says nothing about how often price reaches it on a given market or timeframe.

The Bottom Line

Traders who spot a W shape on daily or weekly charts can use the double bottom to frame entries, stops and targets from the pattern itself. The signal counts only after a close above the intermediate high, ideally on rising volume, and the confirmed trade often offers little more reward than risk. Treat measured targets as reference points and expect some breakouts to fail.
