}

A detected harmonic pattern. Points are labelled X, A, B, C, D; x_* is populated only for the 5-0 (four-point AB=CD patterns have no X). is_bull is true when the pattern completes at a low (a buy setup).

Fields

id: u32

kind: HarmonicKind

is_bull: bool

x_bar: Option<usize>

x_price: Option<f64>

a_bar: usize

a_price: f64

b_bar: usize

b_price: f64

c_bar: usize

c_price: f64

d_bar: usize

d_price: f64

score: f64

Ratio-fit quality in [0, 1]; 1.0 is a textbook-exact pattern.

xa_ext: Option<f64>

5-0 only: |AB| / |XA| (the B-point extension of XA).

bc_ab: f64

|BC| / |AB| — a retracement (< 1) for AB=CD, an extension (> 1) for 5-0.

cd_ab: f64

|CD| / |AB| — 1.0 for AB=CD, 1.27/1.618 for Alternate, ~1.0 for 5-0.

cd_bc: f64

|CD| / |BC| — ~0.5 for the 5-0 completion.

d_xa: Option<f64>

XABCD (Gartley family) only: D as a retracement/extension of the XA leg — the pattern’s defining number (0.786 Gartley, 0.886 Bat, 1.27 Butterfly, 1.618 Crab, 1.13 Alternate Bat). None for AB=CD and 5-0.

prz_low: f64

Potential Reversal Zone (price band where the pattern projects to complete).

prz_high: f64

size_atr: f64

Vertical extent of the pattern (max − min pivot price) in ATR units.
