Struct AdvancedZigZagEngine 

pub struct AdvancedZigZagEngine { /* private fields */ }

Advanced ZigZag engine with backstep, ATR-mode deviation, and explicit confirmation status.

Implementations

impl AdvancedZigZagEngine

pub fn new( depth: usize, backstep: usize, deviation: ZigZagDeviationMode, atr_len: usize, ) -> Self

pub fn with_defaults() -> Self

pub fn nodes(&self) -> &[ZigZagNode]

Confirmed swing history, oldest first.

pub fn current_leg(&self) -> Option<&ZigZagNode>

The still-forming leg’s current extreme, if any (may not yet be in Self::nodes or may be the unconfirmed last entry there).

pub fn reduce(nodes: &[ZigZagNode], deviation_pct: f64) -> Vec<ZigZagNode>

Recursively re-simplifies an already-reduced node sequence at a coarser deviation threshold, the “dual-/recursive levels” swing-degree technique: apply the same alternating-extreme simplification to the higher-degree input instead of raw bars.

pub fn project_to_timeframe( nodes: &[ZigZagNode], target_tf: Timeframe, utc_offset_seconds: i32, ) -> Vec<ZigZagNode>

Projects a node sequence onto a higher timeframe’s bucket grid, keeping only the most extreme high/low node per bucket per side — the confirmed HTF-equivalent swing points an LTF zigzag implies.
