# The Shark Pattern: A Modern Harmonic Setup

Introduction

The Shark pattern is a relatively new addition to the family of harmonic patterns, discovered by Scott Carney in 2011. It is a unique and versatile pattern that can be used to identify high-probability trading opportunities in a variety of market conditions. This article provides a detailed examination of the Shark pattern, covering its structure, the mathematical ratios that define it, and the specific trading rules for its successful application.

The Structure of the Shark Pattern

The Shark pattern is a five-point pattern, but unlike other harmonic patterns, its points are labeled O, X, A, B, and C. The pattern is characterized by a deep retracement of the initial OX leg and a final C point that extends beyond the initial O point. The pattern is defined by a specific set of Fibonacci ratios:

LegRetracement/ExtensionRatio(s)
XRetracement of OA0.382 - 0.618
ARetracement of OX1.13 - 1.618
BRetracement of OA1.618 - 2.24
CRetracement of OB0.50

The most important element of the Shark pattern is the C point, which is a 50% retracement of the OB leg. The formula for calculating the C point in a bullish Shark pattern is:

C = O + (B - O) * 0.50

The 5-0 Pattern: The Aftermath of the Shark

The Shark pattern is often followed by another pattern called the 5-0 pattern. The 5-0 pattern is a five-point pattern that is formed by the O, X, A, B, and C points of the Shark pattern. The 5-0 pattern is a reversal pattern that can be used to trade the reversal of the Shark pattern.

Trading Rules for the Shark Pattern

Successful trading of the Shark pattern requires a disciplined approach and adherence to a set of well-defined rules. These rules cover entry, stop-loss placement, and profit-taking.

Entry Strategy

The entry for a Shark pattern trade is at the C point, which is the completion of the pattern. As with all harmonic patterns, it is advisable to wait for confirmation before entering a trade. Confirmation can come from:

  • Price Action: A reversal candlestick pattern, such as a pin bar or an engulfing pattern, at the C point.
  • Indicator Divergence: A divergence between the price and an oscillator, such as the RSI or MACD.
  • Volume: A spike in volume at the C point, indicating a capitulation move.

Stop-Loss Placement

The stop-loss for a Shark pattern trade should be placed beyond the C point. A common technique is to place the stop-loss at the 0.618 retracement of the OB leg.

Profit-Taking Strategy

The profit targets for a Shark pattern trade are typically based on the Fibonacci retracement levels of the BC leg. The most common profit targets are the 0.382 and 0.618 retracement levels.

A Numerical Example of a Shark Pattern Trade

Let's consider a bullish Shark pattern on the stock of Tesla, Inc. (TSLA):

PointPriceDescription
O$800The starting point of the pattern, a significant low.
X$900A sharp rally from the low at O.
A$850A retracement from the high at X.
B$950A rally from the low at A.
C$875The completion of the pattern and the entry point for a long trade. This is a 50% retracement of the OB leg ($800 + ($950 - $800) * 0.50).
  • Entry: A trader might enter a long position at $876 after observing a bullish engulfing candle form at the C point.
  • Stop-Loss: The stop-loss would be placed below the C point, at $870.
  • Profit Targets: The first profit target would be the 0.382 retracement of the BC leg, at $903.50. The second profit target would be the 0.618 retracement of the BC leg, at $921.50.

Conclusion

The Shark pattern is a modern and effective harmonic pattern that can provide traders with high-probability trading opportunities. Its unique structure and relationship with the 5-0 pattern make it a valuable tool for identifying trend reversals. By mastering the identification of the Shark pattern and adhering to a disciplined set of trading rules, professional traders can enhance their ability to profit from the financial markets.
