Introduction

This is ta-rs-improved, an improved version of the technical indicator library in Rust. There are two notable changes that makes this application improved.

• Dynamic Window Sizes. This means you can do a 30 day SMA and a 15 hour SMA.
• Correct calculation of the Relative Strength Index (RSI)

This library is used to power NexusTrade, an AI-Powered automated investing research platform. NexusTrade allows even non-technical users to perform financial research, create automated strategies, and optimize those strategies with an easy-to-use UI. Users can then deploy their strategies live to the market with the click of a button.

These indicators are implemented in NexusTrade. NexusTrade is an AI-Powered algorithmic trading platform that lets users create, test, optimize, and deploy automated trading strategies. Try it now for free!

Getting started

Add to you Cargo.toml:

[dependencies]
ta = { git = "https://github.com/austin-starks/ta-rs-improved" }

Example:

use ta::indicators::ExponentialMovingAverage;
use ta::Next;

let mut ema = ExponentialMovingAverage::new(Duration::seconds(3)).unwrap(); // window size of 3 seconds
let now = Utc::now();

assert_eq!(ema.next((now, 2.0)), 2.0);
assert_eq!(ema.next((now + Duration::seconds(1), 5.0)), 3.5);
assert_eq!(ema.next((now + Duration::seconds(2), 1.0)), 2.25);
assert_eq!(ema.next((now + Duration::seconds(3), 6.25)), 4.25);

See more in the examples here. Check also the documentation.

Basic ideas

Indicators typically implement the following traits:

• Next<T> (often Next<f64>) - to feed and get the next value
• Reset - to reset an indicator
• Debug
• Display
• Default
• Clone

So far there are the following indicators available.

• Trend
  • Exponential Moving Average (EMA)
  • Simple Moving Average (SMA)
• Oscillators
  • Relative Strength Index (RSI)
• Other
