Gartley

Reversal at the PRZAlso called: Gartley 222

The original harmonic pattern. A five-point XABCD shape where B retraces about 61.8% of XA and D ends near 78.6% of XA.

What it shows

The Gartley describes a correction within a trend. D is the point where the correction is expected to end and the original direction to resume.

How the scanner finds it
  • Four confirmed swings X, A, B and C. AB retraces 58% to 66% of XA and BC retraces 38.2% to 88.6% of AB.
  • The PRZ (potential reversal zone) is where two projections overlap: AD at 76% to 81% of XA, and CD at 113% to 161.8% of BC. No overlap, no pattern.

How the alerts work for this pattern

  1. 1
    Forming

    C is confirmed. The PRZ is drawn on the chart before price gets there.

  2. 3
    Close to signaling

    Price comes within a third of an ATR of the PRZ.

  3. 4
    Time to act

    Price touches the near edge of the PRZ.

  4. x
    Cancelled

    Price closes beyond C first, or takes more than twice the B to C time.

The textbook trade

Trigger
A touch of the near edge of the PRZ.
Stop
Beyond the far edge of the PRZ, plus half an ATR.
Target
61.8% of the AD leg back.

Things to watch

  • The ratios have a tolerance. A pattern at the edge of every range is a weaker fit than one near the middle.
  • D lies inside the X to A leg. If price goes far beyond X, the pattern has failed.
Where it comes from

H. M. Gartley, Profits in the Stock Market (1935); it is often called the "222" after the page it appears on. Fibonacci ratios were added later by Larry Pesavento and by Scott M. Carney, Harmonic Trading, Volume One (2004).

Education, not advice. A pattern describes what many traders watch for; it does not predict what price will do. The textbook stop and target are reference levels, not instructions. Trading involves risk.
