The Shark is a newer harmonic pattern with its own distinctive labelling. Instead of XABCD, it is mapped as 0-X-A-B-C, and it completes at point C. It often precedes deeper harmonic structures and is known for aggressive, fast reversals after a liquidity grab.
Defining ratios
- AB extends 113% to 161.8% of the XA leg.
- BC extends 161.8% to 224% of AB.
- C completes in the 88.6% to 113% zone of the 0-X leg.
- The pattern uses 0-X-A-B-C rather than XABCD labelling.
The Shark's completion zone around 88.6%–113% means C can slightly overshoot the 0 point, sweeping liquidity before reversing. This makes it feel like a stop hunt followed by a snap-back, which is why confirmation right at C is essential.
Trading the Shark
Enter at C as the completion zone reacts, with a stop just beyond C. Because the Shark often runs into a deeper pattern next, many traders take a quick target and stay nimble rather than holding for a large move. Treat it, like all harmonics, as subjective and probabilistic — never a certainty.
The Shark completes at C in the 88.6%–113% zone using 0-X-A-B-C labelling — a fast reversal trade with a stop just beyond C.
