Stock 15-Minute Return Prediction

Experiments for predicting stock 15-minute returns using high-frequency features.

Data

  • Features: alpha158 computed on 1-minute data
  • Target: 15-minute forward returns (close[t+16]/close[t+1]-1)
  • Normalization: industry, cs_zscore, or dual

Notebooks

Notebook Purpose
01_data_exploration.ipynb Load and explore 15m data structure
02_baseline_model.ipynb Train baseline XGBoost model

Methodology

  1. Load 1-minute kline data via Polars lazy frames
  2. Compute/retrieve alpha158 features
  3. Calculate 15-minute forward returns
  4. Apply normalization (industry-neutralized or cross-sectional z-score)
  5. Train gradient boosting models
  6. Evaluate with IC and backtest
