Struct TdPressure 

pub struct TdPressure { /* private fields */ }

TD Pressure volume-weighted pressure oscillator.

Implementations

impl TdPressure

pub fn new(period: usize) -> Result<Self>

Construct a TD Pressure with the given averaging window. A common default in DeMark’s literature is period = 5.

Errors

Returns Error::PeriodZero if period == 0.

pub const fn period(&self) -> usize

Configured window.

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

Latest emitted value if available.

Trait Implementations

impl Clone for TdPressure

fn clone(&self) -> TdPressure

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TdPressure

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

Formats the value using the given formatter.

impl Indicator for TdPressure

type Input = Candle

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, candle: Candle) -> 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.
