The Gartley Pattern is one of the most traded harmonic patterns, which can be applied to many markets and timeframes. Its a 5-point retracement structure that was originally outlined by H.M. Gartley and detailed further by Scott Carney. It has specific Fibonacci measurements for each point within its structure and it's important to note that D is not a point, but rather a zone in which price is likely to reverse, called the Potential Reversal Zone (PRZ). The B point retracement of the primary XA leg lies at 0.618 and the PRZ consists of 3 converging harmonic levels: 1) 0.786 retracement of the primary XA leg, 2) AB=CD pattern and 3) the BC projection is either 1.27 or 1.618.
The first target would be the 382 retracement of AD and the second target the 618 retracement of AD. The stop would go behind the X-point. Conservative traders look for additional confirmation. Gartley Patterns can be bearish and bullish. TradingView has a smart XABCD Pattern
