Struct CentralPivotRange 

pub struct CentralPivotRange { /* private fields */ }

Central Pivot Range (CPR) — the classic pivot point flanked by two “central” levels whose separation gauges the day’s expected character.

pivot = (high + low + close) / 3
bc'   = (high + low) / 2
tc'   = 2·pivot − bc'
TC    = max(tc', bc'),   BC = min(tc', bc')

The CPR is computed from the previous period’s bar (feed it completed daily/weekly bars). The width of the range TC − BC is the headline read: a narrow CPR signals a likely trending day (price has little balance area to chew through), while a wide CPR signals a likely range-bound, balanced day. Price opening above the whole range is bullish, below it bearish, inside it neutral. The tc'/bc' formulas are symmetric about the pivot; this implementation labels the larger as TC and the smaller as BC so TC >= BC always holds.

There are no parameters and no warmup — each completed bar yields one CPR. Each update is O(1).

Example

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

let mut indicator = CentralPivotRange::new();
let prev_day = Candle::new(101.0, 110.0, 90.0, 105.0, 1_000.0, 0).unwrap();
let cpr = indicator.update(prev_day).unwrap();
assert!(cpr.tc >= cpr.bc);

Implementations

impl CentralPivotRange

pub const fn new() -> Self

Construct a new Central Pivot Range. The indicator is parameter-free.

Trait Implementations

impl Clone for CentralPivotRange

fn clone(&self) -> CentralPivotRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CentralPivotRange

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

Formats the value using the given formatter.

impl Default for CentralPivotRange

fn default() -> CentralPivotRange

Returns the “default value” for a type.

impl Indicator for CentralPivotRange

type Input = Candle

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

type Output = CentralPivotRangeOutput

Type of one output value.

fn update(&mut self, candle: Candle) -> Option<CentralPivotRangeOutput>

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.
