Struct DcConfig 

pub struct DcConfig { /* private fields */ }

Configuration for the Donchian Channel (Dc) indicator.

The Donchian Channel tracks the highest high and lowest low over a rolling window of length bars. The source is always the OHLC high/low extremes — the source field is fixed to [PriceSource::Close] and has no effect on computation.

Example

use quantedge_ta::DcConfig;

let config = DcConfig::builder().build();
assert_eq!(config.convergence(), 20);

Trait Implementations

impl Clone for DcConfig

fn clone(&self) -> DcConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DcConfig

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

Formats the value using the given formatter.

impl Display for DcConfig

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

Formats the value using the given formatter.

impl Hash for DcConfig

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IndicatorConfig for DcConfig

type Builder = DcConfigBuilder

Builder type for constructing this config.

fn builder() -> Self::Builder

Returns a new builder with default values.

fn source(&self) -> PriceSource

Price source to extract from each bar.

fn convergence(&self) -> usize

Bars until compute returns Some

impl IndicatorConfigBuilder<DcConfig> for DcConfigBuilder

fn source(self, _source: PriceSource) -> Self

Sets the price source.

fn build(self) -> DcConfig

Builds the config. Panics if required fields are missing.

impl PartialEq for DcConfig

fn eq(&self, other: &DcConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
