Struct StrategyFactory 

pub struct StrategyFactory { /* private fields */ }

Creates built-in and host strategies by name.

Ten price-action strategies need only strategies; twelve more use the public study calculations when studies is enabled. Inputs are available through Strategy::study_inputs and edited through Strategy::set_input. Entry size and pyramiding come from super::BacktestSettings. Built-ins ignore fill callbacks and decide at bar close, or on forming-bar updates when tick recalculation is enabled.

use egui_charts::strategies::StrategyFactory;
use egui_charts::studies::InputValue;

let factory = StrategyFactory::new();
let mut strategy = factory.create("Consecutive Up/Down").unwrap();
strategy.set_input("length", InputValue::Length(3)).unwrap();
assert!(!strategy.study_inputs().is_empty());
