[−][src]Struct ta::indicators::RateOfChange
Rate of Change (ROC)
Formula
ROC = (Pricet - Pricet-n) / Pricet-n * 100
Where:
- ROC - current value of Rate of Change indicator
- Pt - price at the moment
- Pt-n - price n periods ago
Parameters
- length - number of periods (n), integer greater than 0
Example
use ta::indicators::RateOfChange; use ta::Next; let mut roc = RateOfChange::new(2).unwrap(); assert_eq!(roc.next(10.0), 0.0); // 0 assert_eq!(roc.next(9.7).round(), -3.0); // (9.7 - 10) / 10 * 100 = -3 assert_eq!(roc.next(20.0).round(), 100.0); // (20 - 10) / 10 * 100 = 100 assert_eq!(roc.next(20.0).round(), 106.0); // (20 - 9.7) / 9.7 * 100 = 106
