RustTI

A configurable technical indicators Rust library for all of your technical analysis needs.

Everything is configurable in the RustTI functions.

Many of the functions accept parameters that allow the caller to move the technical indicators away from their default behaviour. For example, if a TI uses the mean to calculate the indicator, it can be told to use the median, or mode instead.

For this reason, RustTI is a more advanced Technical Inidcators package, and users should have some knowledge of the indicators they plan on using.

Examples

Simple Example

Single example, where the moving average needs to be calculated for the entire vector

use rust_ti;

let prices = vec![100.2, 100.46, 100.53, 100.38, 100.19];

let ma = rust_ti::moving_average::single::moving_average(
    &prices,
    &rust_ti::MovingAverageType::Simple
);
assert_eq!(100.352, ma);

let sma = rust_ti::moving_average::single::moving_average(
    &prices,
    &rust_ti::MovingAverageType::Smoothed
);
assert_eq!(100.34228938600666, sma);

let ema = rust_ti::moving_average::single::moving_average(
    &prices,
    &rust_ti::MovingAverageType::Exponential
);
assert_eq!(100.32810426540287, ema);

// The values used in the example for the personalised moving average are random.
// If using the PMA, it is recommended to look into how the moving averages are calculated before using values.
let pma = rust_ti::moving_average::single::moving_average(
    &prices,
    &rust_ti::MovingAverageType::Personalised(&5.0, &3.0)
);
assert_eq!(100.27405995388162, personalised_ma);

Bulk example, where the moving average is calculated for a period.

Behind the scenes, the function will be calculating the moving average for a period of 3. The slices [100.2, 100.46, 100.53], [100.46, 100.53, 100.38], and [100.53, 100.38, 100.19] will be derived from prices. The function will return the moving averages for the 3 periods as a vector.

let prices = vec![100.2, 100.46, 100.53, 100.38, 100.19];
let period: usize = 3;

let ma = rust_ti::moving_average::bulk::moving_average(
    &prices,
    &rust_ti::MovingAverageType::Simple,
    &period
);
assert_eq!(
    vec![100.39666666666666, 100.456666666666666, 100.36666666666667],
    ma
);

let sma = rust_ti::moving_average::bulk::moving_average(
    &prices,
    &rust_ti::MovingAverageType::Smoothed,
    &period
);
assert_eq!(
    vec![100.43842105263158, 100.4442105263158, 100.32157894736842],
    sma
);

let ema = rust_ti::moving_average::bulk::moving_average(
    &prices,
    &rust_ti::MovingAverageType::Exponential,
    &period
);
assert_eq!(
    vec![100.46285714285715, 100.4342857142857, 100.29285714285713],
    pma
);

let pma = rust_ti::moving_average::bulk::moving_average(
    &prices,
    &rust_ti::MovingAverageType::Personalised(&5.0, &3.0),
    &period
);
assert_eq!(
    vec![100.5125581395349, 100.40279069767443, 100.22441860465118],
    pma
);

S&P 500 Example

An example using the Rust TI for the S&P 500 can be found in GitHub

and under examples/main.rs

The code in examples/main.rs can be run by cloning the repo, and running:

cargo build
cargo run --example sp500

Available indicators:

All indicators are grouped and split into modules based on their analysis area.

The modules are split into two sub modules: bulk and single.

Bulk indicators calculate the indicator for a given period and return a vector of the indicator.

Single indicators calculate the indicator for the entire vector and return a single value.
