The Gartley Pattern and Its Synergy with Butterfly Spreads

Introduction to the Gartley Pattern

The Gartley pattern is a harmonic chart pattern that is based on Fibonacci numbers. It was first introduced by H.M. Gartley in his book "Profits in the Stock Market." The pattern is a five-point reversal pattern that can be used to identify potential turning points in the market. This article will provide a detailed analysis of the Gartley pattern and explore its synergy with the butterfly spread.

Constructing a Gartley Pattern

The Gartley pattern consists of five points: X, A, B, C, and D. The pattern is defined by the following Fibonacci ratios:

• The AB leg should be a 0.618 retracement of the XA leg.
• The BC leg should be a 0.382 or 0.886 retracement of the AB leg.
• The CD leg should be a 1.272 or 1.618 extension of the BC leg.
• The AD leg should be a 0.786 retracement of the XA leg.

Formula for Gartley Pattern:

$B = XA \times 0.618$ $C = AB \times (0.382 \text{ or } 0.886)$ $D = BC \times (1.272 \text{ or } 1.618)$ $D = XA \times 0.786$

Synergy with the Butterfly Spread

The Gartley pattern can be a effective tool for identifying entry and exit points for butterfly spreads. The completion of a Gartley pattern at point D often signals a reversal in the market, which is the ideal condition for a butterfly spread. A trader who identifies a bullish Gartley pattern could enter a long call butterfly spread with the expectation that the stock will trade in a narrow range around the completion of the pattern.

Actionable Example: Gartley Pattern and Butterfly Spread

A trader identifies a bullish Gartley pattern on the daily chart of stock XYZ. The pattern completes at point D, which is at a price of $100. The trader decides to enter a long call butterfly spread with the following options:

• Buy 1 XYZ 95 Call
• Sell 2 XYZ 100 Calls
• Buy 1 XYZ 105 Call

Conclusion

The Gartley pattern is a effective tool for identifying potential turning points in the market. When used in conjunction with the butterfly spread, it can provide traders with a high-probability strategy for profiting from low-volatility market conditions. By understanding the construction of the Gartley pattern and its synergy with the butterfly spread, professional traders can enhance their trading performance.
