“The Deep Crab pattern evolved from two patterns—invalid Bat patterns and a specific type of Crab pattern that Scott Carney developed as a further refinement of the basic structure. The Deep Crab is similar to the original Crab pattern, as it is a 5-point extension structure that utilizes exclusively a 161.8% XA projection for the defining level in the Potential Reversal Zone (PRZ).The difference can be found at the B point which must be an 88.6% retracement of XA. In fact, the Deep Crab pattern usually possesses a B point that is beyond the 88.6% level but it does not violate the initial point (X).
