The Shark pattern, discovered by Scott Carney, is a five-point reversal pattern that is one of the newer harmonic patterns. It is a unique pattern that is similar to the M and W patterns, but it is defined by specific Fibonacci ratios. The Shark pattern is a reversal pattern that can be used to predict where the next reversal in the market will be. It is a high-probability pattern that can be used in all timeframes and in all markets.

Anatomy of the Shark Pattern

The Shark pattern is composed of five points: 0, X, A, B, and C. These points form four distinct legs: 0X, XA, AB, and BC. The pattern can be either bullish or bearish, depending on the direction of the initial 0X leg.

  • Bullish Shark: The 0X leg is a strong upward move, and the pattern signals a potential bullish reversal at point C.
  • Bearish Shark: The 0X leg is a strong downward move, and the pattern signals a potential bearish reversal at point C.

Fibonacci Ratios in the Shark Pattern

The Shark pattern is defined by a specific set of Fibonacci ratios that distinguish it from other harmonic patterns. The most important of these is the 1.130 extension of the 0X leg, which defines the C point.

LegFibonacci RatioDescription
XANo specific ratioThe XA leg can be any length.
AB1.130 to 1.618 extension of XAThe B point must be an extension of the XA leg.
BC1.618 to 2.240 extension of ABThe C point is a significant extension of the AB leg.
0C0.886 to 1.130 extension of 0XThe C point, the completion of the pattern, must be an 88.6% to 113% extension of the initial 0X leg.

The Shark Pattern Formula

The mathematical representation of the Shark pattern is as follows:

B = XA * (1.130 to 1.618)
C = AB * (1.618 to 2.240)
C = 0X * (0.886 to 1.130)

Trading the Shark Pattern

Trading the Shark pattern requires a good understanding of its structure and a disciplined approach. The pattern's ability to identify reversals at extreme price levels makes it a valuable tool for traders looking to enter the market at the beginning of a new trend.

Entry and Exit Strategy

  • Entry: The entry point for a Shark pattern trade is at point C, the completion of the pattern. For a bullish Shark, a long position is initiated at C. For a bearish Shark, a short position is initiated at C.
  • Stop-Loss: The stop-loss is placed just below point C for a bullish Shark and just above point C for a bearish Shark.
  • Take-Profit: The take-profit levels are typically set at the 50% and 61.8% retracements of the BC leg.

Example: Bearish Shark in EUR/JPY

Consider a bearish Shark pattern forming on the daily chart of EUR/JPY. The 0X leg is a strong downward move from 135.00 to 130.00. The XA leg is a retracement to 132.00. The AB leg extends to 128.00, a 1.618 extension of the XA leg. Finally, the C point completes the pattern at 136.13, which is a 1.130 extension of the 0X leg.

PointPrice (EUR/JPY)
0135.00
X130.00
A132.00
B128.00
C136.13

In this scenario, a trader would initiate a short position at 136.13, with a stop-loss just above 136.13. The take-profit levels would be set at 132.06 (50% retracement of BC) and 131.00 (61.8% retracement of BC).

Conclusion

The Shark pattern is a effective reversal pattern that can help traders identify high-probability trading opportunities at extreme price levels. Its unique structure and reliance on specific Fibonacci ratios make it a valuable addition to any trader's toolkit. However, like all harmonic patterns, the Shark pattern should be used in conjunction with other forms of technical analysis and a sound risk management strategy. By mastering the Shark pattern, traders can improve their ability to spot reversals and capitalize on new trends.
