Struct ADX 

pub struct ADX { /* private fields */ }

Average Directional Index (ADX) calculator

Measures trend strength (not direction). Values above 25 typically indicate a strong trend, while values below 20 suggest a ranging market.

Also provides +DI and -DI for trend direction via trend_direction().

Implementations

impl ADX

pub fn new(period: usize) -> Self

Create a new ADX with the given period

pub fn update(&mut self, high: f64, low: f64, close: f64) -> Option<f64>

Update with HLC data, returning the ADX value if warmed up

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

Get the current ADX value

pub fn plus_dir_index(&self) -> Option<f64>

Get the +DI value

pub fn minus_dir_index(&self) -> Option<f64>

Get the -DI value

pub fn trend_direction(&self) -> Option<TrendDirection>

Returns trend direction based on DI crossover.

• +DI > -DI → Bullish
• -DI > +DI → Bearish

pub fn is_ready(&self) -> bool

Check if the ADX has enough data

pub fn period(&self) -> usize

Get the period

pub fn reset(&mut self)

Reset the ADX state

fn clone(&self) -> ADX

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ADX

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