In any case, the pattern contains a bullish or bearish ABCD pattern, but is preceded by a point (X) that is beyond point D.
The “perfect” Gartley pattern has the following characteristics:
Move AB should be the .618 retracement of move XA. Move BC should be either .382 or .886 retracement of move AB. If the retracement of move BC is .382 of move AB, then CD should be 1.272 of move BC. Consequently, if move BC is .886 of move AB, then CD should extend 1.618 of move BC. Move CD should be .786 retracement of move XA
