Machine Learning Feature Engineering for Financial Predictions

machine learning feature engineering predictive analytics
Prompt
Create a PostgreSQL pipeline that prepares advanced machine learning features for financial time-series prediction. Develop SQL functions that generate complex derived features including rolling volatility, exponential moving averages, relative strength indices, and cross-asset momentum indicators. The solution must support dynamic feature generation, handle missing data intelligently, and output standardized feature matrices compatible with scikit-learn and TensorFlow machine learning frameworks.
