YaTa implements most common technical analysis [methods](https://docs.rs/yata/latest/yata/methods/index.html#structs)
and [indicators](https://docs.rs/yata/latest/yata/indicators/index.html#structs).
It also provides you an interface to create your own indicators.

## Method usage example
```rust
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
```rust
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`](https://crates.io/crates/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](https://github.com/amv-dev/yata/issues) about implementing new indicators and methods.
