## Feature Engineering

+### ACF/PACF Analysis
+
+Serial autocorrelation analysis confirmed predictive relevance of key engineered features:
+
+| Feature Group | Autocorrelation Finding | Implication |
+|--------------|------------------------|-------------|
+| Session-tagged returns | Significant lag-1 autocorrelation during London+NY overlap | Session labelling is predictive |
+| ADX (2-period) | Strong partial autocorrelation at lags 1–3 | Short-window ADX captures momentum persistence |
+| CCI ratio (2/20) | Decaying ACF with slow taper | CCI ratio is a trend-following signal, not noise |
+| Keltner width | Significant at lag-1, drops at lag-2 | ATR-based volatility is a 1-bar leading indicator |
