Technical analysis library for Rust.

## Status

The library is in development.

## Goals
* Implement flexible and easy to use library in pure Rust
* Support most popular technical analysis indicators
* Have a good documentation for every indicator

## Roadmap

That's the list of things to be done before first stable release 0.1.0.
More indicators can be added later.

* [ ] Indicators
  * [x] Trend
    * [x] EMA
    * [x] SMA
  * [ ] Oscillators
    * [x] RSI
    * [x] Fast stochastic
    * [x] Slow stochastic
    * [ ] MACD
  * [x] Other
    * [x] Minimum
    * [x] Maximum
    * [x] True Range
    * [x] Average True Range
    * [x] Rate of Change
* [ ] Good test coverage
  * Unit tests
  * Integration tests
  * Ensure every indicators implements traits:
    * Default
    * Next<T>
    * Reset
    * Display
    * Debug
    * Clone
* [ ] Documentation
  * Good README and lib doc, that explain the idea behind traits `Next<T>`, `Reset`.
  * `How to contribute` section in README
  * Every indicator must have:
    * Description
    * Formula
    * Example


## Get started

Add to you `Cargo.toml`:
```
[dependencies]

ta = "*"
```

Example:

```rust
use ta::indicators::ExponentialMovingAverage;
use ta::Next;

let mut ema = ExponentialMovingAverage::new(3).unwrap();
assert_eq!(ema.next(2.0), 2.0);
assert_eq!(ema.next(5.0), 3.5);
assert_eq!(ema.next(1.0), 2.25);
assert_eq!(ema.next(6.25), 4.25);
```
