Double Top & Double Bottom

What Is the Double Top and Double Bottom?

The double top and double bottom are among the most frequently occurring reversal patterns in forex. They represent the market’s failure to break through a significant price level on two separate attempts — and that failure triggers a reversal.

A double top forms when price reaches a resistance level, pulls back, rallies back to the same level, and fails again. The resulting neckline break signals a bearish reversal.

A double bottom is the mirror image: price hits support, bounces, drops back to the same support, and bounces again. The neckline break signals a bullish reversal.

With a 72-73% success rate according to Bulkowski’s research, these patterns offer reliable trading opportunities — especially when combined with volume analysis and indicator divergence.

How to Identify the Double Top

Structure

The double top has four phases:

1. First peak — Price rallies to a resistance level and pulls back, establishing the neckline
2. Pullback — Price retraces to an intermediate support level (this becomes the neckline)
3. Second peak — Price rallies back to the same resistance level (within 1-3%) and fails again
4. Neckline break — Price breaks below the pullback low, confirming the reversal

The double bottom mirrors this structure at market lows.

Key Identification Rules

The peaks must be at a similar level. They do not need to be at the exact same price, but they should be within a reasonable tolerance. A second peak that falls significantly short of the first suggests a head and shoulders rather than a double top.

There must be a preceding trend. A double top requires a prior uptrend; a double bottom requires a prior downtrend. Without a preceding trend, what looks like a double top is just range-bound price action.

Adequate separation between the peaks. The two tests should be separated by enough time and price movement to represent distinct attempts at the level. A general guideline is 20 or more candles between the peaks on your trading timeframe.

Divergence Confirmation

One of the strongest confirmation signals is indicator divergence between the two peaks. If price makes two equal highs (double top) while RSI or MACD makes a lower high, it confirms that momentum is fading. This divergence significantly improves the pattern’s reliability.

Trading Rules

Entry

Standard entry: Enter when a candle closes below the neckline (double top) or above the neckline (double bottom). This confirms the break and reduces false signal risk.

Retest entry: After the neckline breaks, price often returns to retest it — the old support becomes new resistance (or vice versa). Entering on this retest gives you a tighter stop and better risk-to-reward, but you will miss trades that move straight through.

Aggressive entry: Some traders enter at the second peak or trough, using a reversal candlestick like an engulfing or pin bar as confirmation. This gives the best entry price but carries higher risk since the pattern is not yet confirmed.

Track which entry method you use in your journal. After 20+ trades, your PipJournal analytics will show which approach gives you the best results.

Target Calculation

Measure the height of the pattern — the distance from the peaks to the neckline. Project that distance from the neckline break point.

Example: If the two peaks are at 1.2500 and the neckline is at 1.2380, the pattern height is 120 pips. If the neckline breaks at 1.2375, your measured move target is 1.2255.

Use the risk-reward calculator to verify that the target gives you at least a 1:1.5 or better risk-to-reward ratio before entering.

Stop Placement

For double tops, place your stop above the higher of the two peaks, plus a buffer of 10-20 pips (depending on the pair’s typical spread and volatility). For double bottoms, place it below the lower of the two troughs.

This stop level represents the invalidation point — if price exceeds both peaks, the pattern has clearly failed.

Journaling This Pattern

Double tops and bottoms are common enough that you can build a meaningful sample size quickly. This makes them ideal candidates for data-driven analysis through journaling.

Record these variables for every double top or bottom trade:

• Pattern type: Double top or double bottom
• Peak/trough levels: Were they at exactly the same level or offset?
• Time between tests: How many candles separated the two peaks?
• Divergence: Was RSI or MACD divergence present?
• Entry method: Break, retest, or aggressive at the second test
• Trend context: Was the pattern with or against the higher timeframe trend?
• Pair: Some pairs form more reliable double tops and bottoms than others

Use PipJournal’s tagging system to segment your results by these variables. You might discover that double bottoms with RSI divergence on EUR/USD have a 85% success rate in your trading, while double tops on GBP/JPY without divergence only hit 55%. That kind of insight only comes from structured data.

Common Mistakes

Calling the pattern too early. The most common mistake is entering at the second peak before the neckline breaks. The second touch is not confirmation — it is anticipation. Many second tests lead to brief pullbacks followed by breakouts through the level.

Ignoring the trend context. A double top forming in a strong bull trend is less reliable than one forming after an extended move where the trend is exhausting. Always assess the broader picture before trading a reversal pattern.

Confusing ranges with double tops. If price has been oscillating between two levels for weeks, a touch of resistance is not a double top — it is range-bound behavior. Double tops require a clear preceding uptrend.

Tight stops. Placing your stop exactly at the second peak invites stop hunts. Allow a buffer. In forex, institutional order flow frequently pushes price slightly past obvious levels before reversing.

When It Fails

Double tops and bottoms fail when:

• The broader trend overwhelms the pattern (a double top in a raging bull market)
• A fundamental catalyst (central bank decision, NFP surprise) drives price through the level
• The pattern forms on a timeframe that is too low, where noise dominates structure

A failed double top can trigger a powerful breakout higher. The two tests of resistance act like a launchpad once the level finally gives way. Conversely, a failed double bottom can lead to an acceleration lower.

Journal your failures alongside your successes. Understanding when and why the pattern fails is just as valuable as knowing when it works. PipJournal’s analytics let you filter your losing double top trades to find common threads — time of day, pair, news proximity — so you can avoid repeating the same mistakes.
