Island Reversal: A Powerful Gap-Based Pattern

Island reversals are one of the most reliable reversal patterns in forex. They’re visually obvious and carry strong psychological weight—when price isolates itself in an “island” before reversing, it’s a sign that the trend is exhausted.

What Is an Island Reversal?

An island reversal occurs when:

1. Price is in a trend (uptrend or downtrend)
2. A gap occurs in the opposite direction of the trend (a gap down in an uptrend, gap up in a downtrend)
3. 1-3 isolated candles form on that gap (separate from the main trend)
4. Another gap occurs in the same direction as the first gap (further away from the trend)
5. Price has created a visual “island” that’s separated from both the previous trend and the new direction

The pattern signals that the trend has lost momentum and is reversing.

Visual Example: Uptrend Island Reversal

Uptrend:    ↑ ↑ ↑ ↑ ↑ ↑

Gap Down:   ↓ (gap occurs)

Island:     ↓ ↓ (1-3 candles isolated)

Gap Down:   ↓ (another gap down)

Result:     Island is now visually separated
            Reversal to downtrend begins

How to Identify Island Reversals

Step 1: Confirm the Trend Is price in a clear uptrend (higher lows, higher highs) or downtrend (lower highs, lower lows)? You need a established trend for a reversal pattern to be meaningful.

Step 2: Spot the First Gap A gap is when price opens below the previous close (in an uptrend) or above the previous close (in a downtrend) with no overlap. The two candles don’t touch.

Step 3: Identify the Island Candles The candles after the first gap that don’t overlap with the trend candles form the “island.” Usually 1-3 candles.

Step 4: Wait for the Second Gap The second gap should occur in the same direction as the first gap, further isolating the island from the trend.

Step 5: Confirm Visually You should now see a clear “island” of candles separated from both the trend and the new direction. This is your signal.

Trading the Island Reversal

Entry Enter when the second gap closes (at the end of the second gap candle). Some traders wait for the next candle to confirm, but entering at the gap close is more aggressive.

Stop Loss 5-10 pips beyond the far edge of the island. If the island is formed by gaps down, your stop is 10 pips below the lowest candle of the island.

Profit Target Measure the trend distance before the reversal. Your target is often 50-100% of that distance in the opposite direction.

Example Trade: EURUSD is in a strong uptrend from 1.0700 to 1.0900 (200 pips).

A gap down occurs at 1.0890 (opens at 1.0885). Two candles form an island. Another gap down at 1.0870 completes the pattern.

You enter short at 1.0870 (on the second gap close). Stop: 1.0880 (10 pips above the island low) Target: 1.0800 (50% of the 200-pip trend)

Risk: 10 pips. Reward: 70 pips. Ratio: 7:1

Price falls to 1.0800. You close 70 pips profit.

Why Island Reversals Work

Psychological: Gaps scare traders. When price gaps away from a trend, momentum players get nervous. When it gaps again away, they panic and exit. This panic selling/buying drives the reversal.

Technical: Gaps often signal capitulation. The island represents the last gasp of buyers (before a downtrend) or sellers (before an uptrend). After that exhaustion, the opposite side takes control.

Volume: Island reversals often have higher volume on the second gap, confirming the shift in momentum.

Common Mistakes

Trading Single-Candle Islands A single candle island is weaker than a 2-3 candle island. More candles on the island = more traders trapped = stronger reversal signal.

Entering Before the Second Gap Entering after the first gap but before the second gap is premature. Wait for both gaps to form the complete pattern.

Target Too Tight Island reversals often deliver 100+ pips. If you target only 30 pips and get stopped at 70, you’re leaving money on the table. Be patient.

Ignoring Volume Low-volume gaps are weak signals. High-volume gaps are strong. If the second gap has lower volume than the first, it might not complete the pattern.

Placing Stop Too Wide A 20-pip stop encourages overholding. Keep your stop tight (5-10 pips). If the pattern fails, exit quickly and move on.

Island Reversals on Different Timeframes

Daily and Weekly Island reversals on daily/weekly are very reliable. They signal major trend reversals that can last weeks/months. Take these seriously.

4-Hour Island reversals on 4H are still reliable. They signal intermediate trend reversals that might last days.

1-Hour Island reversals on 1H are noisier. They work but with lower reliability. Use them more as confirmation of 4H/daily patterns.

Avoid 1H islands on volatile pairs (GBPTRY, EURMXN) because noise creates false patterns.

Multi-Timeframe Island Reversals

A “super island reversal” occurs when:

• Daily has a completed island reversal
• 4H has a completed island reversal
• 1H is about to reverse into alignment

This is maximum conviction. Risk big (within your 1% rule) when all three align.

Journaling Island Reversals

1. Log the Trend Distance From trend start to reversal point (in pips). This helps you calculate targets.

2. Record Gap Sizes First gap size and second gap size. Larger gaps = stronger pattern.

3. Document Volume Was volume high on the gaps? Higher volume = stronger signal.

4. Note the Number of Island Candles 1 candle vs. 3 candles. Track which count produces better results on your pairs.

5. Record Entry Timing Did you enter on the second gap or after confirmation? Compare win rates.

6. Track Target Achievement Did price reach your target? How far before reversing? This teaches you optimal target distance.

Tools

Use the Pip Calculator to calculate position size based on your tight 5-10 pip stop. Island reversals allow wider targets, so your R:R is favorable.

Final Thought

Island reversals are reliable because they’re visual, they have psychological weight, and they often come with volume confirmation. They’re most powerful on daily/weekly charts where they signal major reversals.

The traders who win with islands are the ones who:

1. Only trade them on 4H+ timeframes
2. Wait for both gaps to complete the pattern
3. Set targets aggressively (not tight)
4. Keep stops tight (5-10 pips)
5. Journal volume and gap sizes to see which setups work best on their pairs

Start watching for island reversals on your charts. Once you see a few, the pattern becomes obvious.
