Technical analysis library for Rust.
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();
asserteq!(ema.next(2.0), 2.0); asserteq!(ema.next(5.0), 3.5); asserteq!(ema.next(1.0), 2.25); asserteq!(ema.next(6.25), 4.25); ```

A data item which represent a stock quote may implement the following traits:
OpenHighLowCloseVolumeIt'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<T> (often Next<f64> and Next<&DataItem>) - to feed and get the next valueReset - to reset an indicatorDebugDisplayDefaultCloneSo far there are the following indicators available.
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.
