Rust

ferro_ta_core is the compute engine. Use it directly from any Rust project — no PyO3, NumPy, or JavaScript runtime.

Installation

[dependencies]
ferro_ta_core = "1.2.0"

Or:

cargo add ferro_ta_core

Docs.rs: https://docs.rs/ferro_ta_core

Basic Usage

Functions take borrowed &[f64] slices and return owned Vec<f64> (or tuples of vectors). Leading warmup bars are NaN.

use ferro_ta_core::{momentum, overlap};

fn main() {
    let close: Vec<f64> = (0..40).map(|i| 44.0 + i as f64 * 0.1).collect();

    let sma = overlap::sma(&close, 5);
    let rsi = momentum::rsi(&close, 14);
    let (macd, signal, hist) = overlap::macd(&close, 12, 26, 9);
    let (upper, middle, lower) = overlap::bbands(&close, 5, 2.0, 2.0);

    assert!(sma[0].is_nan());
    assert!(rsi[13].is_nan());
}
