Reusable Code Examples

Using Hurst for Regime Detection

use ml::features::price_features::PriceFeatureExtractor;

let hurst = PriceFeatureExtractor::compute_hurst_exponent(&bars, 20);

// Regime classification
if hurst > 0.6 {
    // Trending regime
} else if hurst > 0.4 && hurst < 0.6 {
    // Ranging regime
} else {
    // Mean-reverting regime
}

Using ATR for Position Sizing

use ml::features::feature_extraction::FeatureExtractor;

let extractor = FeatureExtractor::new();
let atr_values = extractor.calculate_atr(&bars);
let current_atr = atr_values.last().unwrap();

// Dynamic position sizing
let position_size = match regime {
    Trending => base_position * (1.0 + hurst * 0.5),    // Larger in trends
    Ranging => base_position * 0.75,                      // Smaller in ranges
    Volatile => base_position * volatility_factor,        // Risk-managed
};

Using Autocorrelation for Regime Detection

use ml::features::statistical_features::StatisticalFeatureExtractor;

let autocorr = StatisticalFeatureExtractor::compute_autocorrelation(&bars, 1);

if autocorr > 0.6 {
    // Persistent (trending)
} else if autocorr < -0.1 {
    // Mean-reverting (ranging)
} else {
    // Neutral/transitional
}
