Struct FastStochastic

pub struct FastStochastic { /* private fields */ }

Fast stochastic oscillator.

The stochastic oscillator is a momentum indicator comparing the closing price of a security to the range of its prices over a certain period of time.

Formula

Where:

• %K_t - value of fast stochastic oscillator
• C_t - close price of the current period
• L_n - lowest price for the last n periods
• H_n - highest price for the last n periods

Parameters

• length - number of periods (integer greater than 0). Default is 14.

Example

use ta::indicators::FastStochastic;
use ta::{Calculate, Next};

let mut stoch = FastStochastic::new(5).unwrap();
assert_eq!(stoch.calc(20.0), 50.0);
assert_eq!(stoch.calc(30.0), 100.0);
assert_eq!(stoch.calc(40.0), 100.0);
assert_eq!(stoch.calc(35.0), 75.0);
assert_eq!(stoch.calc(15.0), 0.0);
