Crate quantwave_core 

quantwave-core

Core technical-analysis engine for QuantWave: 221 native indicators, Ehlers DSP, price-action detectors, regime features, and the Next<Input> streaming trait that powers batch/streaming parity.

Quick start (streaming)

use quantwave_core::indicators::RSI;
use quantwave_core::traits::Next;

let mut rsi = RSI::new(14);
let value = rsi.next(44.5);

Architecture

• Indicators — indicators module; each implements Next for scalar streaming
• Batch — consumed by quantwave-polars / quantwave-plugins expression plugins
• Features / regimes — ML-oriented transforms in features and regimes
