YATA

Yet Another Technical Analysis library

YaTa implements most common technical analysis methods and indicators.

It also provides you an interface to create your own indicators.

Method usage example

use yata::prelude::*;
use yata::methods::EMA;

// EMA of length=3
let mut ema = EMA::new(3, &3.0).unwrap();

ema.next(&3.0);
ema.next(&6.0);

assert_eq!(ema.next(&9.0), 6.75);
assert_eq!(ema.next(&12.0), 9.375);

Indicator usage example

use yata::helpers::{RandomCandles, MA};
use yata::indicators::MACD;
use yata::prelude::*;

let mut candles = RandomCandles::new();
let mut macd = MACD::default();

macd.method1 = "sma-4".parse().unwrap(); // one way of defining methods inside indicators

macd.signal = MA::TEMA(5); // another way of defining methods inside indicators

let mut macd = macd.init(&candles.first()).unwrap();

for candle in candles.take(10) {
	let result = macd.next(&candle);

	println!("{:?}", result);
}

Current unsafe status

By default, there is no unsafe code in the crate. But you can optionally enable unsafe_performance feature throw you Cargo.toml or by --feature flag in your CLI.

unsafe_performance enables some unsafe code blocks, most of them are unsafe access to a vector's elements. For some methods it may increase performance by ~5-10%.

Features

• serde - enables serde crate support;
• period_type_u16 - sets PeriodType to u16;
• period_type_u32 - sets PeriodType to u32;
• period_type_u64 - sets PeriodType to u64;
• value_type_f32 - sets ValueType to f32;
• unsafe_performance - enables optional unsafe code blocks, which may increase performance;

Rust version

YaTa library supports Rust stable except that you can't run benchmarks with it.

Suggestions

You are welcome to give any suggestions about implementing new indicators and methods.
