Struct Supertrend 

pub struct Supertrend { /* private fields */ }

Supertrend trend-direction indicator.

Returns +1 for uptrend, -1 for downtrend at each bar.

Example

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

let ts = Utc::now();
let candles: Vec<Candle> = (0..20).map(|i| {
    let d = rust_decimal::Decimal::from(i);
    Candle::new(dec!(100) + d, dec!(110) + d, dec!(90) + d, dec!(105) + d, dec!(1000), ts).unwrap()
}).collect();
let st = Supertrend::new(10, dec!(2)).unwrap();
let series = st.compute(&candles).unwrap();

Implementations

impl Supertrend

pub fn new( atr_period: usize, multiplier: Decimal, ) -> Result<Self, IndicatorError>

Create a new Supertrend indicator.

Parameters

• atr_period: ATR lookback period (standard: 10–14)
• multiplier: Band width multiplier (standard: 2.0–3.0)

Errors

Returns InvalidParameter if atr_period is 0 or multiplier is non-positive.

pub fn atr_period(&self) -> usize

Accessors for config (used by signal generators that need the params).

pub fn multiplier(&self) -> Decimal

Trait Implementations

impl Clone for Supertrend

fn clone(&self) -> Supertrend

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Supertrend

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

Formats the value using the given formatter.

impl Indicator for Supertrend

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.
