Struct HtTrendMode 

pub struct HtTrendMode { /* private fields */ }

Ehlers’ Hilbert Transform Trend Mode (HT_TRENDMODE).

Runs the same adaptive Hilbert-transform engine as HilbertDominantCycle, derives the dominant cycle phase, its sine / lead-sine, and an instantaneous trendline, then classifies the market into trend mode (1) or cycle mode (0):

• it is a cycle shortly after the sine and lead-sine cross, while the phase advances at roughly the dominant-cycle rate;
• it is a trend otherwise, and is forced to trend whenever price separates from the trendline by more than 1.5%.

From Rocket Science for Traders (Ehlers 2001), aligned with TA-Lib’s HT_TRENDMODE. The output is 1.0 or 0.0; the first value is emitted after ~50 inputs once the engine’s moving-average chain has filled.

Example

use wickra_core::{Indicator, HtTrendMode};

let mut ht = HtTrendMode::new();
let mut last = None;
for i in 0..120 {
    last = ht.update(100.0 + f64::from(i));
}
assert!(last.is_some());

Implementations

impl HtTrendMode

pub fn new() -> Self

Construct a new Hilbert transform trend-mode classifier.

pub const fn value(&self) -> Option<f64>

Current trend-mode flag (1.0 trend, 0.0 cycle) if available.

Trait Implementations

impl Clone for HtTrendMode

fn clone(&self) -> HtTrendMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HtTrendMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for HtTrendMode

fn default() -> HtTrendMode

Returns the “default value” for a type.

impl Indicator for HtTrendMode

type Input = f64

Type of one input data point (typically f64 for a price, or Candle / Tick).

type Output = f64

Type of one output value.

fn update(&mut self, input: f64) -> Option<f64>

Feed one new data point into the indicator and return the freshly computed output, or None if the indicator is still warming up.

fn reset(&mut self)

Reset all internal state, leaving the indicator equivalent to a freshly constructed instance with the same parameters.

fn warmup_period(&self) -> usize

Number of inputs required before the first non-None output can be produced.

fn is_ready(&self) -> bool

Whether the indicator has emitted at least one value since the last reset.

fn name(&self) -> &'static str

Stable, human-readable indicator name. Used by chaining and diagnostics.
