“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).
