Struct ta::indicators::ChandelierExit

pub struct ChandelierExit { /* fields omitted */ }

Chandelier Exit (CE).

Developed by Charles Le Beau and featured in Alexander Elder’s books, the Chandelier Exit sets a trailing stop-loss based on the Average True Range (ATR). The indicator is designed to keep traders in a trend and prevent an early exit as long as the trend extends. Typically, the Chandelier Exit will be above prices during a downtrend and below prices during an uptrend.

Formula

Chandelier Exit (long) = Max(period) - ATR(period) * multipler Chandelier Exit (short) = Min(period) + ATR(period) * multipler

Parameters

• period - number of periods (integer greater than 0). Default is 22.
• multipler - ATR factor. Default is 3.

Example

use ta::indicators::ChandelierExit;
use ta::{Next, DataItem};

let value1 = DataItem::builder()
.open(21.0).high(22.0).low(20.0).close(21.0).volume(1.0).build().unwrap();
let value2 = DataItem::builder()
.open(23.0).high(24.0).low(22.0).close(23.0).volume(1.0).build().unwrap();

let mut ce = ChandelierExit::default();

let first = ce.next(&value1);
assert_eq!(first.long, 16.0);
assert_eq!(first.short, 26.0);

let second = ce.next(&value2);
assert_eq!((second.long * 100.0).round() / 100.0, 17.74);
assert_eq!((second.short * 100.0).round() / 100.0, 26.26);
