Module registry 

Indicator registry — create indicators by name at runtime.

Mirrors indicators/registry.py and indicators/factory.py:

• IndicatorRegistry ↔ class IndicatorRegistry
• register! macro ↔ @register_indicator decorator
• IndicatorFactory::create(name, params) ↔ IndicatorFactory.create(name, **params)

Usage

use crate::registry::REGISTRY;

// list what's available
let names = REGISTRY.list();

// create by name with typed params map
let params = [("period", "20")].into();
let indicator = REGISTRY.create("sma", params).unwrap();
let output = indicator.calculate(&candles).unwrap();
