Struct NakedPoc 

pub struct NakedPoc { /* private fields */ }

Naked (Virgin) POC — the nearest untested point of control from a prior session: a heavily-traded price the market has not traded back through since.

every `session_len` candles forms a session; its POC (heaviest-volume price) is
  recorded as "naked"
a naked POC becomes "tested" once a later candle's high-low range covers it
output = the nearest still-naked POC to the current close (or the close itself
  if every prior POC has been revisited)

A point of control is a magnet — price tends to return to fair value. A naked (or virgin) POC is one that has not yet been revisited, so it carries an outstanding “pull”: untested POCs are high-probability targets and support/resistance on the approach. This indicator records each completed session’s POC, marks them tested as price trades through them, and reports the closest one still outstanding.

The first value lands after session_len candles (the first session’s POC). Each update is O(session_len · bins + naked-count).

Example

use wickra_core::{Candle, Indicator, NakedPoc};

let mut indicator = NakedPoc::new(20, 24).unwrap();
let mut last = None;
for i in 0..60 {
    let base = 100.0 + (f64::from(i) * 0.2).sin() * 5.0;
    let c = Candle::new(base, base + 1.0, base - 1.0, base, 1_000.0, 0).unwrap();
    last = indicator.update(c);
}
assert!(last.is_some());

Implementations

impl NakedPoc

pub fn new(session_len: usize, bins: usize) -> Result<Self>

Construct a Naked POC tracker with the given session_len and profile bins.

Errors

Returns Error::PeriodZero if session_len or bins is zero.

pub const fn params(&self) -> (usize, usize)

Configured (session_len, bins).

pub fn naked_count(&self) -> usize

Number of currently-naked POCs.

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

Current value if available.

Trait Implementations

impl Clone for NakedPoc

fn clone(&self) -> NakedPoc

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NakedPoc

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

Formats the value using the given formatter.

impl Indicator for NakedPoc

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.
