Min — Lowest Value Over Period — min

The lowest value in the input series over a rolling period window.

Inputs: [real] | Options: [period] | Outputs: [min]

Basic

use tulip_rs::indicators::min::{Min};

let close = vec![81.59, 81.06, 82.87, 83.00, 83.61,
                 83.15, 82.84, 83.99, 84.55, 84.36_f64];
let (outputs, mut state) = Min::indicator(&[close.as_slice()], &[14.0], None).unwrap();
println!("{:?}", outputs[0]);

// State continuation — feed new bars without reprocessing history
let partial = close[..8].to_vec();
let (outputs2, mut state) = Min::indicator(&[partial.as_slice()], &[14.0], None).unwrap();
println!("{:?}", outputs2[0]);

let new_close = vec![85.53_f64];
let continued = state.batch_indicator(&[new_close.as_slice()], None).unwrap();
println!("{:?}", continued[0]);

outputs, state = tulip_rs.indicators.min.indicator([close], [14.0])
print(outputs[0])

SIMD

By assets — same options, N assets in parallel:

use tulip_rs::indicators::min::{Min, Indicator};

let inputs: [&[&[f64]; 1]; 4] = [&[a1.as_slice()], &[a2.as_slice()], &[a3.as_slice()], &[a4.as_slice()]];
let results = Min::indicator_by_assets::<4>(&inputs, &[14.0], None).unwrap();
for (i, asset_outputs) in results.iter().enumerate() {
    println!("Asset {}: {:?}", i + 1, asset_outputs[0]);
}

By options — same asset, N option sets in parallel:

use tulip_rs::indicators::min::{Min, IndicatorByOptions};

let opts: [&[f64; 1]; 4] = [&[5.0], &[10.0], &[20.0], &[50.0]];
let results = Min::indicator_by_options::<4>(&[close.as_slice()], &opts, None).unwrap();
for (i, asset_outputs) in results.iter().enumerate() {
    println!("Option {}: {:?}", i + 1, asset_outputs[0]);
}

By assets — same options, N assets in parallel (must be 2, 4, 8, or 16):

simd_inputs = [[a1], [a2], [a3], [a4]]
outputs_list, states = tulip_rs.indicators.min.simd_by_assets(simd_inputs, [14.0])

By options — same asset, N option sets in parallel:

simd_options = [[5.0], [10.0], [20.0], [50.0]]
outputs_list, states = tulip_rs.indicators.min.simd_by_options([close], simd_options)

By assets — same period applied to 4 assets in parallel:

const simdInputs = [[close.slice()], [close.map(v => v * 1.1)], [close.map(v => v * 0.9)], [close.map(v => v * 1.02)]];
const [results] = ti.min.simdByAssets(simdInputs, [14]);
results.forEach((out, i) => console.log(`Asset ${i + 1}:`, out[0]));

By options — same asset, 4 different periods in parallel:

const simdOptions = [[5], [10], [20], [50]];
const [results] = ti.min.simdByOptions([close], simdOptions);
results.forEach((out, i) => console.log(`Period ${simdOptions[i][0]}:`, out[0]));
