[−][src]Struct ta::indicators::EfficiencyRatio
Kaufman's Efficiency Ratio (ER).
It is calculated by dividing the price change over a period by the absolute sum of the price movements that occurred to achieve that change. The resulting ratio ranges between 0.0 and 1.0 with higher values representing a more efficient or trending market.
Parameters
- length - number of periods (integer greater than 0)
Example
use ta::indicators::EfficiencyRatio; use ta::Next; let mut er = EfficiencyRatio::new(4).unwrap(); assert_eq!(er.next(10.0), 1.0); assert_eq!(er.next(13.0), 1.0); assert_eq!(er.next(12.0), 0.5); assert_eq!(er.next(13.0), 0.6); assert_eq!(er.next(18.0), 0.8); assert_eq!(er.next(19.0), 0.75);
