Dynamically dispatchable IndicatorConfig

Required Methods

fn init( &self, initial_value: &T ) -> Result<Box<dyn IndicatorInstanceDyn<T>>, Error>

Dynamically initializes the State based on the current Configuration

fn over(&self, inputs: &dyn AsRef<[T]>) -> Result<Vec<IndicatorResult>, Error>

Evaluates dynamically dispatched IndicatorConfig over series of OHLC and returns series of IndicatorResults

use yata::prelude::dd::*;
use yata::helpers::{RandomCandles};
use yata::indicators::Trix;

let candles: Vec<_> = RandomCandles::new().take(10).collect();
let static_config = Trix::default();
let dyn_config: Box<dyn IndicatorConfigDyn<_>> = Box::new(static_config); // here we are loosing information about `IndicatorConfig`s type.
let results = dyn_config.over(&candles).unwrap();
println!("{:?}", results);

fn name(&self) -> &'static str

Returns a name of the indicator

fn validate(&self) -> bool

Validates if Configuration is OK

fn set(&mut self, name: &str, value: String) -> Result<(), Error>

Dynamically sets Configuration parameters

fn size(&self) -> (u8, u8)

Returns an IndicatorResult size processing by the indicator (count of raw values, count of signals)
