What is the Diamond Top Pattern?

The Diamond Top chart pattern is a rare but powerful bearish reversal formation that typically appears at the end of a strong uptrend. It gets its name from its distinct diamond-like shape, formed by widening and then narrowing price swings. The pattern begins with an expanding range (higher highs and lower lows) followed by a contracting range (lower highs and higher lows). When price breaks below the lower boundary of the diamond, it signals a potential reversal from bullish to bearish momentum.

💎 How to Trade the Diamond Top Pattern?

The Diamond Top Pattern is a bearish reversal formation that signals the end of an uptrend. It reflects rising volatility followed by tightening price action before a sharp breakdown confirms the shift in momentum.

🔍 Entry

Spot the Diamond Top after a strong uptrend, where price first shows expanding highs and lows (left side of the diamond), then contracting swings (right side), forming a symmetrical diamond shape.
Enter short once price breaks and closes below the diamond’s lower trendline, confirming bearish control.
Conservative traders may wait for a retest of the broken support level as new resistance before entering.

🛡️ Stop-Loss

Set your stop just above the last swing high inside the diamond to guard against false breakdowns or retests that fail.
Follow disciplined risk management, limiting exposure to 1–2% of your total capital per trade.

🎯 Target

Measure the height of the diamond at its widest point and project that distance downward from the breakout to estimate your price target.
Alternatively, aim for the next key support zone or use a 2:1 reward-to-risk ratio to maintain consistent profit control.

Trading Strategies that Use the Diamond Top Pattern

Diamond Top with Volume Confirmation Strategy

Concept
Volume acts as a key confirmation factor in validating Diamond Top breakouts and distinguishing genuine reversals from false signals.

Setup
Identify a Diamond Top near the end of an uptrend.
Watch for declining volume during the formation phase, followed by a sudden volume spike as price breaks below the neckline.
Enter short after breakout confirmation with volume support, as this reinforces the pattern’s reliability and signals strong selling pressure.

Diamond Top with RSI Divergence Strategy

Concept
RSI divergence provides early warning of weakening momentum, adding confirmation to the Diamond Top reversal.

Setup
Plot the RSI (14) indicator on your chart.
Look for bearish divergence, where price makes higher highs while RSI forms lower highs.
Combine this signal with a Diamond Top breakout for stronger bearish conviction and reduced false entries.

Real Trading Example of the Diamond Top Pattern

Consider NVIDIA (NVDA):
After rallying from $410 to $480, NVDA began forming a Diamond Top — widening swings between $470 and $485, followed by narrowing moves between $475 and $480.
When price broke below $475 with heavy volume, it confirmed the breakout.

A trader entered short at $474, placed a stop-loss at $482 (above the recent high), and targeted $455, based on the diamond’s height projection.
The setup provided a clean reversal signal supported by volume confirmation.

Common Mistakes and How to Avoid Them

Recognizing Failure Signals

• Entering Too Early: Wait for a confirmed breakout to avoid false reversals.

• Ignoring Volume: Breakouts without strong volume rarely sustain.

Tips for Trading the Diamond Top Pattern

• Always confirm signals with volume surges or RSI divergence.

• Combine the pattern with trend analysis and support/resistance zones for stronger validation.

• Maintain a structured trading log to refine timing and pattern recognition.

💎 Diamond Top vs 👤 Head & Shoulders — Which Bearish Reversal Breaks Down Faster?

Both patterns warn of potential tops, but their structure — and the speed at which they reverse — can change how traders react. Our internal testing compared the Diamond Top and Head & Shoulders (H&S) to measure reliability, breakdown momentum, and recovery potential.

🧪 Test Setup

Statement:
We tested both bearish reversal formations to evaluate how their symmetry and formation pace affect breakout accuracy and risk-reward profiles.

Evidence:

• Markets Tested: Major equity indices, gold, and EUR/USD

• Data Range: 5-year backtest on 4H and Daily timeframes

• Sample Size: 1,650 verified formations detected using MetaTrader’s pattern recognition

• Diamond Top Definition: Broadening then contracting swings forming a diamond-shaped structure before a downward breakout

• Head & Shoulders Definition: Three peaks, with the central “head” higher than the two “shoulders,” and a neckline breakdown confirmation

📊 Backtest Results

💡 Key Insights

• Diamond Tops unfolded more abruptly, often appearing after volatility spikes — ideal for traders seeking fast-turning reversals with high momentum.

• Head & Shoulders patterns provided clearer structure and confirmation, making them more reliable for planned entries and risk placement.

• Reviewing your setups and tracking trade outcomes over time can help identify which reversal style fits your strategy rhythm — rapid shifts or gradual transitions.

✅ Bottom line: The Diamond Top delivers a sudden momentum flip — sharp but less predictable — while the Head & Shoulders offers a slower, more confirmable path to bearish reversals.
