From Theory to Practice: A Comprehensive Case Study of Trading a Gartley Pattern in Albemarle (ALB)

This series of articles has explored the theory and application of harmonic patterns in the battery metals sector. Now, it is time to put it all together in a comprehensive case study. This article will provide a step-by-step walkthrough of identifying, validating, and trading a bullish Gartley pattern in the stock of Albemarle (ALB), the world's largest lithium producer.

Step 1: Identifying the Pattern

The first step is to identify a potential Gartley pattern on the daily chart of ALB. We are looking for a five-point reversal pattern with the following characteristics:

  • XA Leg: A strong upward price move.
  • AB Leg: A 0.618 retracement of the XA leg.
  • BC Leg: A 0.382 to 0.886 retracement of the AB leg.
  • CD Leg: A 1.272 to 1.618 extension of the BC leg, with the D point being a 0.786 retracement of the XA leg.

After scanning the chart, we identify a potential bullish Gartley pattern with the following points:

  • X: $100
  • A: $150
  • B: $120 (a 0.600 retracement of XA)
  • C: $140 (a 0.667 retracement of AB)
  • D (PRZ): $110.70 (a 0.786 retracement of XA)

Step 2: Validating the Pattern

Once we have identified a potential pattern, the next step is to validate it with other technical indicators. We are looking for a confluence of signals that will increase our confidence in the trade.

  • RSI: The RSI is in oversold territory, suggesting that the downward momentum is exhausted.
  • MACD: The MACD is showing a bullish divergence, with the price making a new low but the MACD failing to do so.
  • Volume: The volume is declining on the CD leg, suggesting that the selling pressure is abating.

Step 3: Formulating a Trading Plan

Now that we have identified and validated the pattern, it is time to formulate a trading plan. This includes defining our entry price, stop-loss, and profit targets.

  • Entry: We will enter a long position as the price enters the PRZ at $110.70.
  • Stop-Loss: We will place a stop-loss order just below the X point at $99.
  • Position Size: With a $100,000 account and a 1% risk per trade, our position size will be: ($100,000 * 0.01) / ($110.70 - $99) = $1,000 / $11.70 = 85 shares
  • Profit Targets: We will take partial profits at the 38.2% retracement of the AD leg ($125.50) and the 61.8% retracement ($134.80).*

Step 4: Executing and Managing the Trade

With our trading plan in place, we are ready to execute the trade. We place a limit order to buy 85 shares of ALB at $110.70. The order is filled, and we are now long ALB.

The stock then begins to rally, and it reaches our first profit target at $125.50. We sell half of our position (42 shares) and move our stop-loss to our entry price of $110.70. This makes the trade risk-free.

The stock continues to rally and reaches our second profit target at $134.80. We sell the remainder of our position and exit the trade.

Conclusion

This case study has demonstrated the power of harmonic patterns in the battery metals market. By combining the predictive power of harmonic patterns with a disciplined approach to risk management, traders can develop a robust and profitable trading strategy. The battery metals sector will continue to be a source of immense opportunity for years to come, and for those who are willing to do their homework, the rewards can be substantial.
