Struct Macd 

pub struct Macd { /* private fields */ }

MACD indicator.

Measures the relationship between two EMAs. Produces three outputs:

• MACD line: fast EMA - slow EMA
• Signal line: EMA of MACD line
• Histogram: MACD - Signal

This implementation returns the MACD line. Use MacdSignal for signal line or MacdHistogram for histogram.

Standard Parameters

• Fast: 12
• Slow: 26
• Signal: 9

Example

use quant_indicators::{Indicator, Macd};
use quant_primitives::Candle;
use chrono::Utc;
use rust_decimal_macros::dec;

let ts = Utc::now();
let candles: Vec<Candle> = (0..30).map(|i| {
    Candle::new(dec!(100), dec!(110), dec!(90), dec!(100) + rust_decimal::Decimal::from(i), dec!(1000), ts).unwrap()
}).collect();
let macd = Macd::new(12, 26).unwrap();
let series = macd.compute(&candles).unwrap();

Implementations

impl Macd

pub fn new( fast_period: usize, slow_period: usize, ) -> Result<Self, IndicatorError>

Create a new MACD indicator.

Arguments

• fast_period - Period for fast EMA (typically 12)
• slow_period - Period for slow EMA (typically 26)

Errors

Returns InvalidParameter if fast >= slow or periods are 0.

pub fn standard() -> Result<Self, IndicatorError>

Create MACD with standard parameters (12, 26).

Trait Implementations

impl Clone for Macd

fn clone(&self) -> Macd

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Macd

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

Formats the value using the given formatter.

impl Indicator for Macd

fn name(&self) -> &str

The name of this indicator (e.g., “SMA(20)”).

fn warmup_period(&self) -> usize

Minimum number of candles required before output is valid.

fn compute(&self, candles: &[Candle]) -> Result<Series, IndicatorError>

Compute the indicator values from candle data.
