Double Top and Double Bottom in Trading

What Is a Double Top or Double Bottom?

A double top is a chart pattern made up of two highs of about the same height with a low between them; a double bottom is its counterpart, made up of two lows with a high between them. On the chart, the double top resembles an M and the double bottom a W. Both are considered reversal patterns, but they are only complete when the price closes beyond the extreme between the two peaks.

Robert D. Edwards and John Magee described both forms in Technical Analysis of Stock Trends (1948) and warned against taking every pair of similar highs for a double top. John J. Murphy summarizes the usual reading in Technical Analysis of the Financial Markets (1999): the pattern exists only with a close beyond this extreme, and its height serves as the measure for the price target.

Among chart patterns, both forms belong to the reversal patterns, as do the triple top and triple bottom and the head and shoulders pattern.

How Do You Identify a Double Top or Double Bottom?

You can spot a double top by a preceding rise, two highs at a similar level, and a clear pullback between them; in a double bottom, the picture is mirrored. The extreme between the peaks gives the neckline, and only a close beyond this line completes the pattern.

• Prior trend: before a double top the price rises, before a double bottom it falls. Without a trend beforehand, there is nothing to reverse.
• Two peaks: both highs or lows sit at a similar level. Small differences are normal, and the second peak does not have to match the first exactly.
• Distance: a clear pullback and enough time lie between the peaks. If they are close together, Edwards and Magee see it more as a pause in the trend.
• Neckline: in a double top it runs horizontally through the low between the highs, in a double bottom through the high between the lows. Some traders draw it at a slant through several lows or highs; the price then crosses it earlier.
• Volume: according to Murphy, volume at the second peak of a double top is usually lower than at the first, and it picks up again at the breakout.
• Completion: the pattern only counts when a candle closes beyond the neckline.

There is no central exchange volume in currency trading; traders there focus mainly on the reaction at the second peak and the close of the breakout candle.

What Lies Behind a Double Top or Double Bottom?

Behind a double top is a failed second attack: buyers push the price back up to the old high but get no further. This suggests that enough sellers are waiting at this level, and each rejection makes more buyers cautious.

The first high hardly stands out when it forms, because at first only a pullback follows. If the price fails on the second attempt, the most recent buyers end up at a loss. If it then falls below the neckline, the sequence of higher highs and higher lows is broken, and the stops of many buyers come within reach.

In a double bottom, it is the other way around: sellers fail twice at the same level. A close above the neckline means the last lower high has been overcome, and many sellers cover their positions.

What Types Are There?

There are two basic forms that mirror each other. Thomas N. Bulkowski also distinguishes by the shape of the individual peaks; also important is the distinction from related patterns with more than two peaks.

Double Top

In a double top, a rise is followed by a high, a pullback, and a second high at a similar level. The neckline sits at the low between them, and a close below it is considered bearish.

Double Bottom

In a double bottom, a decline is followed by a low, a recovery, and a second low at a similar level. The neckline sits at the high between them, and a close above it is considered bullish.

Adam and Eve

In the Encyclopedia of Chart Patterns, Bulkowski describes the peaks by their shape: a narrow, pointed turn is called “Adam”, a wide, rounded one “Eve”. This gives four combinations: Adam and Adam, Adam and Eve, Eve and Adam, Eve and Eve. This changes nothing about the neckline and price target, but it helps to read even peaks that look different as one pattern.

Distinction from Triple Top and Head and Shoulders

If the price fails three times at a similar level, it is a triple top. If the middle one of three highs clearly stands out, it is a head and shoulders pattern.

When Does the Breakout Count, and When Does It Not?

A double top only counts when a candle closes below the neckline, a double bottom when it closes above it. Until then, two similar highs can also be just a pullback in the ongoing trend, after which the price rises above both peaks.

The pattern can also fail after the breakout: if the price closes back on the old side of the neckline and then beyond the two peaks, it is void, and the move often continues in the old direction. A mere return to the neckline, on the other hand, is not yet a failure, as long as the price does not close back on the old side.

In the false-signal chart, the price first falls and forms lows at 104.80 and 105.00 with a high at 109.60 between them. The breakout candle closes at 110.35, above the neckline. Three candles later, the price closes at 108.80, back below it, and eight candles after the breakout it closes at 104.15, below the line through the two lows, which is at 105.20 there. The double bottom has failed, and the decline continues.

Example of Entry, Stop, and Price Target

For a structured trade with a double top, traders wait for the close below the neckline instead of selling at the second high. According to Murphy, the price target follows from the height of the pattern, measured downward from the neckline; for the stop, there is a tight and a wide variant.

In the chart, the price first rises and then forms highs at 110.20 and 110.02 with a low at 104.30 between them; the pattern is therefore 5.90 points high. The breakout candle closes at 103.25, below the neckline, and a trader sells at the close. The stop goes just above the last intermediate high before the breakout, at 106.10; the risk is 2.85 points. The price target is 5.90 points below the neckline, at 98.40. Three candles after the breakout, the price returns to the neckline, reaching 104.20, and closes below it. It reaches the price target after 11 candles, which is 4.85 points from the entry. This gives a risk/reward ratio of about 1:1.7.

The wide variant would be a stop just above the higher peak, here at 110.30. The risk would then be 7.05 points, more than the reward of 4.85 points, and the ratio about 1:0.7. The tight stop improves the ratio but is reached more easily; you should therefore decide before entering which variant fits your plan.

How Do You Use Double Tops and Bottoms Across Multiple Timeframes?

Comparing several timeframes shows whether a double top signals a turn in the larger trend or is just a pause on the lower chart. A double top on the lower chart carries more weight when it forms at a resistance on the higher chart or when that chart is itself already turning down.

If, for example, a double top forms on the 1h chart while the 4h and 1d charts are clearly rising, it is often just a pullback in the larger uptrend, and the price target remains doubtful. If the two highs sit at a resistance on the 1d chart, on the other hand, the pattern fits into the overall picture. FinScans shows the trend across the eight timeframes on the signal page and in the cockpit.

How Do News and Scheduled Events Affect Double Tops and Bottoms?

Double tops and bottoms build up over many candles and can be invalidated by a single scheduled event: a price jump after economic data or an interest rate decision can cut through the neckline in one candle without the two peaks before it saying anything about it. You should therefore check whether a breakout falls into such a reaction.

Anyone who checks the economic calendar before entering can see whether an upcoming event could soon put the neckline to the test. Anyone who also checks the news situation in the cockpit can tell whether the breakout comes from the ongoing market or has a report behind it.

How Do You Use Double Tops and Bottoms in the Four Trading Styles?

Depending on the trading style and timeframe, the distance between the two peaks, the height of the pattern, and therefore the distance to stop and price target vary considerably. On short charts the peaks are often only hours apart, on high timeframes weeks.

Double Tops and Bottoms in Scalping

In scalping on the 15m and 30m charts, double tops often form at the high or low of a session, when the price runs to the same mark a second time and turns away. On these charts, many pairs of similar highs are only short pauses; scalpers therefore demand a clear pullback between the peaks and compare the direction with the 1h or 2h chart. A double bottom on a rising 1h chart fits the picture, while a double top on the same chart runs against the larger trend. Entry comes only after the close beyond the neckline, and the stop goes behind the last intermediate extreme. Because the pattern here is only a few points high, the spread eats a noticeable part of the target; if this leaves the ratio of reward to risk too thin, scalpers skip the trade. Trading focuses on the start of the London and New York sessions, when more movement comes into the market; in the quiet Asian session, many double peaks turn into a sideways phase. Positions stay open for a few minutes to a few hours and are closed before the end of the session.

Double Tops and Bottoms in Day Trading

In day trading on the 1h and 2h charts, the two peaks are often many hours apart, and positions are closed before the end of the trading day. The higher-level context comes from the 4h and 8h charts. A typical picture: the price forms a high in the London session, pulls back, and in the overlap with New York runs up to the same level once more without overcoming it. Day traders then wait for the candle to close below the neckline and place the stop above the last intermediate high. On these charts, the price target from the height of the pattern is not always reached before the end of the trading day; they then take profits at the previous day's high or low. If the breakout comes only toward the end of the New York session or shortly before an important scheduled event, many skip the entry. If the price returns to the neckline from the outside after the breakout, this pullback offers a second entry point with a tighter stop.

Double Tops and Bottoms in Swing Trading

In swing trading on the 4h and 8h charts, traders hold positions for days to a few weeks; the two peaks here are often several days apart. For context, swing traders consult the 12h and 1d charts. A double bottom at a zone of support and resistance on the daily chart carries more weight for them than one in the middle of a range. After the close of the breakout candle, the stop goes below the last intermediate low in a double bottom and above the last intermediate high in a double top, while the price target is compared with higher-level zones. Since the position runs overnight and often over the weekend, swing traders allow for overnight risk and, in currencies, possible weekend gaps, while cryptocurrencies trade continuously. If a pullback to the neckline holds after the breakout, many trail the stop behind this new extreme. If the price instead closes back on the old side of the line, they exit the position early rather than wait for the stop.

Double Tops and Bottoms in Position Trading

In position trading on the 12h and 1d charts, trades last weeks to months; a double top on the daily chart can mark the end of a large uptrend. There is no timeframe higher than 1d in FinScans; the context therefore comes from the 1d chart over several months. The warning from Edwards and Magee applies well here: if the two highs are only a few days apart, it is more of a pause; a distance of several weeks makes the pattern more credible. A double top after a rise lasting several months is a reason for existing long positions to tighten the stop or take partial profits even before the breakout. Position traders open new positions only when a daily candle closes beyond the neckline, and at the same time they check whether interest rate policy and macro data support the direction. Because the pattern is tall on this chart, the price target and stop sit far from the entry; position traders cushion weekend gaps and interest rate decisions with a smaller position size.

Double Top or Triple Top?

Both patterns show highs that were rejected several times and are only complete with a close beyond the neckline. The difference lies in the number of peaks and in the time the pattern needs.

In a triple top, the price fails three times, and the neckline connects two lows. If a double top stays incomplete and the price runs up from the neckline a third time, it can turn into a triple top. The price target is derived the same way for both: from the height of the pattern, measured from the neckline.

What Mistakes Are Common with Double Tops and Bottoms?

Many losses when trading these patterns come from anticipating them or declaring any two highs to be one. What counts is therefore the prior trend, the distance between the peaks, and a full candle close.

• Entering before the neckline: anyone selling at the second high is betting on a pattern that does not yet exist; from there, the price can also rise above both highs.
• Peaks too close together: two highs just a few candles apart are usually only a hesitation in the trend, not a double top.
• No prior trend: two highs in a sideways phase are the upper boundary of a range, not the turn of a trend.
• Wick instead of close: a wick beyond the neckline does not complete the pattern; only the candle close counts.
• Accepting stop and target without looking at the chart: if strong support sits well before the price target, or if the position size is not adjusted to the stop distance as part of sound risk management, the ratio of reward to risk tips.

How the Triggers Are Named in FinScans Signals

On the signal page, the triggers appear in the trigger table, each with an arrow: ▲ means FinScans counts the trigger on the bullish side, ▼ on the bearish side. Two names stand for the pattern itself:

• “Double Top” (▼): double top with two highs at a similar level.
• “Double Bottom” (▲): double bottom with two lows at a similar level.

Both triggers can appear before the price has closed beyond the extreme between the peaks, because a neckline can also be drawn at a slant. According to the textbook, the pattern is not yet complete at that moment, so comparing it with the chart remains your task.

On older signals, you will also find two names containing “Retreat”. At FinScans, the word stands for a bounce: the price runs to the neckline and turns away instead of breaking through it. The pattern is therefore not completed, which is why the arrow points the opposite way:

• “Double Top Retreat Up” (▲): after the second high, the price bounces upward from the neckline.
• “Double Bottom Retreat Down” (▼): after the second low, the price bounces downward from the neckline.

For these triggers, the signal page also shows a class. It describes how the trigger came about in the last candles:

Such a trigger rarely stands alone: FinScans combines it with the other triggers of the same signal into an overall direction. Whether it runs with or against the larger move is shown by the trend across the eight timeframes and the overall assessment.

The following block shows current data on these triggers. The hit rate should always be read relative to the average: if it is above, the trigger has a statistical edge; if it is below, it is better used as a hint than as the sole reason to enter. The rates can vary considerably by trading style, because there is more noise on short timeframes. The distances to target and stop also play a role: a tight stop is hit more often than a wide one, a distant target less often than a near one.

What the Machine Reports, What You Check Yourself

On the signal page, the triggers appear with their arrow and class for the monitored forex and crypto pairs. Whether the two peaks on the chart really belong together and whether the breakout falls into a consistent environment is something you check yourself in the spirit of hybrid trading.

• The machine reports “Double Top” or “Double Bottom”; you check on the chart whether a trend came before it and whether the peaks are clearly separated at a similar level.
• The signal page shows trigger and class; you check whether a candle has already clearly closed beyond the horizontal neckline or whether only a wick extends through it.
• The machine provides the trend across eight timeframes; you check whether a nearby support and resistance zone on the higher chart blocks the path to the price target.
• The data block shows the hit rate so far; you check the economic calendar to see whether an upcoming event such as an interest rate decision could trigger a false breakout.
• The signal page gives target and stop; you compare them with the height of the pattern and the last intermediate extreme and size the position according to your risk management.

Frequently asked questions

Is a Double Top Bullish or Bearish?

According to the textbook, it is bearish, and a double bottom is correspondingly bullish. This is only settled, however, when a candle closes beyond the neckline; until then, two similar highs are just an observation, and the price can rise above both.

How Do You Calculate the Price Target of a Double Top?

You measure the height of the pattern from the higher peak to the neckline and project it downward from the neckline; for a double bottom, the same applies upward. The result is a guide: if a strong zone lies before it, many traders take some profit there.

How Far Apart Must the Two Peaks Be?

There is no fixed number, because the distance depends on the timeframe. According to Edwards and Magee, the highs on the daily chart should be several weeks apart. On every chart, a clearly visible pullback should lie between the peaks.

What Applies If the Price Rises Above Both Peaks After the Second High?

If the price closes beyond both peaks before the neckline has given way, the pattern is void, and the trend simply continues. If this happens after a breakout, the breakout has failed, and many traders close their position by then at the latest.
