Double bottom pattern

A bullish reversal pattern with two lows at the same support, complete when price closes above the high between them.

SupportNecklineMeasured targetFirst lowSecond lowBreakout
A double bottom: two lows hold the same support, the neckline runs through the high between them, and the rally after the close above it is about as tall as the pattern.

A double bottom pattern forms when price falls to a low, bounces, falls again and holds near the same level. On the chart it looks like the letter W, which is why traders also call it the W pattern. It is complete only when price closes above the neckline – the high between the two lows.

What is a double bottom pattern

A double bottom is a bullish reversal pattern. After a downtrend price makes a low, bounces, then returns to the same area and holds. Sellers tried to extend the decline twice and failed at the same level.

It is the mirror image of the double top pattern and is read the same way on stocks, crypto, forex and commodities.

How to identify a double bottom chart pattern

On Charts the trend line and rectangle tools mark the support and the neckline. What to check:

  • Prior downtrend – the pattern needs a decline to reverse. Two equal lows in a sideways market are just a range.
  • Two lows at about the same level – an exact match is rare. The second low can hold slightly above the first or dip slightly below it.
  • A clear high between the lows – the bounce should stand out on the chart, and the lows should be well separated in time.
  • Neckline – a horizontal line through the high between the lows. It acts as resistance until it breaks.
  • Volume – often lower on the second low and higher on the breakout above the neckline.
  • Confirmation – a candle close above the neckline. Until then the pattern is not complete.

The W pattern: what each leg shows

The W pattern has four legs. The first leg down is the end of the downtrend. The first leg up is a bounce that sets the neckline. The second leg down tests whether sellers can make a new low. The second leg up is the breakout: buyers take price through the neckline.

The second low matters most. A low that holds on lower volume, or with a higher RSI reading than at the first low, is read as selling pressure fading.

How to trade a double bottom pattern

A double bottom gives a long trade, and only after the neckline breaks.

  • Entry – on the candle close above the neckline, or on a pullback to the neckline from above. Pullbacks are common, but not every breakout gives one.
  • Stop – below the second low. A stop just below the neckline is tighter, but a deeper pullback takes it out more often.
  • Target – the measured target: the height of the pattern, from the lows up to the neckline, added to the neckline.
  • Example – lows at 100, neckline at 123. The pattern is 23 points tall, so the measured target is 123 + 23 = 146.
  • The target is an estimate, not a level price has to reach. The nearest resistance on the way is a common place to take part of the profit.

When the second low is higher or lower

A second low slightly above the first shows buyers stepping in earlier. Traders read it as the stronger version of the pattern.

A second low that dips below the first and closes back above it takes out the stops under the first low before turning. In smart money terms this is a liquidity sweep. It is still a double bottom as long as price does not close and stay below the first low.

Common mistakes with the double bottom pattern

  • Buying the second low before the breakout – in a downtrend a level that held once often breaks on the next test.
  • Calling any two lows a W pattern – without a prior decline and a clear bounce between the lows there is nothing to reverse.
  • Lows too close together – two lows a few candles apart are one bottom, not two.
  • Ignoring a failed pattern – a close below both lows cancels the double bottom, and the downtrend continues.
  • Chasing a breakout far above the neckline – the stop below the second low is then too far away for the size of the target.

Frequently asked questions

What is a double bottom pattern?

A bullish reversal pattern of two lows at about the same level with a high between them. It forms after a downtrend and is confirmed when price closes above that high, called the neckline.

Is a double bottom pattern bullish or bearish?

Bullish. It marks a failed second attempt to break support and is read as a reversal from a downtrend to an uptrend.

What is a W pattern in trading?

Another name for the double bottom. The two lows and the bounce between them draw the letter W. The opposite shape, the M pattern, is the double top.

How do you calculate the target of a double bottom chart pattern?

Add the height of the pattern to the neckline. With lows at 100 and a neckline at 123, the height is 23 and the target is 146.

Double bottom vs inverse head and shoulders: what is the difference?

A double bottom has two lows at about the same level. An inverse head and shoulders pattern has three, with the middle one lower. Both are bullish reversals confirmed by a close above the neckline.

Does the double bottom chart pattern appear on every timeframe?

Yes. The shape appears on any timeframe and in any liquid market. Patterns built over weeks on a daily or weekly chart get more attention than intraday ones, where false breakouts are more frequent.
