## Getting started
Add to you `Cargo.toml`:
```
[dependencies]
ta = "0.4.0"
```
Example:
```rust
use ta::indicators::ExponentialMovingAverage;
use ta::Next;
// it can return an error, when an invalid length is passed (e.g. 0)
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);
```
See more in the examples [here](https://github.com/greyblake/ta-rs/tree/master/examples).
Check also the [documentation](https://docs.rs/ta).
## Basic ideas
A data item which represent a stock quote may implement the following traits:
* `Open`
* `High`
* `Low`
* `Close`
* `Volume`
It's not necessary to implement all of them, but it must be enough to fulfill requirements for a particular indicator.
You probably should prefer using `DataItem` unless you have reasons to implement your own structure.
Indicators typically implement the following traits:
* `Next` (often `Next` and `Next<&DataItem>`) - to feed and get the next value
* `Reset` - to reset an indicator
* `Debug`
* `Display`
* `Default`
* `Clone`
## List of indicators
So far there are the following indicators available.
* Trend
* Exponential Moving Average (EMA)
* Simple Moving Average (SMA)
* Oscillators
* Relative Strength Index (RSI)
* Fast Stochastic
* Slow Stochastic
* Moving Average Convergence Divergence (MACD)
* Percentage Price Oscillator (PPO)
* Commodity Channel Index (CCI)
* Money Flow Index (MFI)
* Other
* Minimum
* Maximum
* True Range
* Standard Deviation (SD)
* Mean Absolute Deviation (MAD)
* Average True Range (AR)
* Efficiency Ratio (ER)
* Bollinger Bands (BB)
* Chandelier Exit (CE)
* Keltner Channel (KC)
* Rate of Change (ROC)
* On Balance Volume (OBV)
## Features
* `serde` - allows to serialize and deserialize indicators. NOTE: the backward compatibility of serialized
data with the future versions of ta is not guaranteed because internal implementation of the indicators is a subject to change.
## Running benchmarks
```
