The Butterfly pattern, developed by Bryce Gilmore, is a harmonic pattern that is similar to the Gartley pattern but with a key difference: the CD leg extends beyond the initial XA leg. This makes the Butterfly pattern a effective tool for identifying potential reversals at the end of extended price moves. This article provides a detailed analysis of the Butterfly pattern and its application in the context of iron ore trading.
Structure and Fibonacci Ratios of the Butterfly Pattern
The Butterfly pattern is a five-point reversal pattern with the following structure for a bullish Butterfly:
- XA Leg: A significant price move.
- AB Leg: A retracement of the XA leg, which must be a 0.786 retracement.
- BC Leg: A price move that retraces the AB leg, typically between 0.382 and 0.886.
- CD Leg: A long and extended leg that completes at the 1.272 or 1.618 extension of the XA leg.
The Potential Reversal Zone (PRZ) for a bullish Butterfly pattern is defined by the 1.272 or 1.618 extension of the XA leg and an extension of the BC leg, typically between 1.618 and 2.618:
PRZ = (1.272 to 1.618) * XA + (1.618 to 2.618) * BC
Trading the Butterfly Pattern in the Iron Ore Market
The iron ore market's tendency for strong trends and sharp reversals makes it a suitable environment for the application of the Butterfly pattern. The following table shows hypothetical price data for iron ore, which can be used to identify Butterfly patterns.

Actionable Example: A Bearish Butterfly Pattern in the Iron Ore Market
Let's consider a bearish Butterfly pattern forming on the daily chart of iron ore prices. A trader identifies the following points:
-
X: A swing low at $100.00 on November 10, 2025.
-
A: A swing high at $150.00 on August 4, 2025.
-
B: A retracement to $110.00 on October 13, 2025, which is a 0.786 retracement of the XA leg.
-
C: A rally to $135.00 on September 29, 2025, which is a 0.886 retracement of the AB leg.
-
D: A rally to the PRZ, calculated as follows:
- 1.272 extension of XA: $100.00 + 1.272 * ($150.00 - $100.00) = $163.60
- 1.618 extension of XA: $100.00 + 1.618 * ($150.00 - $100.00) = $180.90
The PRZ is identified as the price range between $163.60 and $180.90. A trader would look for signs of a bearish reversal within this zone and could initiate a short position with a stop-loss placed above the PRZ.
Conclusion
The Butterfly pattern is a valuable tool for identifying potential reversals at the end of extended price moves in the iron ore market. By understanding the specific Fibonacci ratios that define the pattern and by combining its signals with a disciplined approach to risk management, traders can enhance their ability to profit from the market's turning points.
