Factor Alpha101 Alpha158 Alpha191

Use this skill to compute deterministic Alpha101, Alpha158, and Alpha191 factor-library values from long-form OHLCV market data.

Core Workflow

1. Read references/input_schema.md before preparing the input JSON.
2. Choose alpha_sets: alpha101, alpha158, alpha191, or any combination.
3. Use alpha_names and exclude_alpha_names to select factors. Qualified names such as alpha101:alpha_001, alpha158:ma.p5, and alpha191:alpha_018 are supported.
4. Run the unified CLI:

python scripts/compute_alpha_factors.py --input examples/compute_input.json

5. Read references/output_contract.md before consuming generated artifacts.

Output Contract

The skill writes wide CSV factor values and JSON metadata under the configured output directory:

• alpha101_values.csv when Alpha101 factors are computed
• alpha158_values.csv when Alpha158 factors are computed
• alpha191_values.csv when Alpha191 factors are computed
• alpha_compute_summary.json
• skipped_factors.json
• run_config.json

Boundaries

This is a factor-library computation skill. It does not compute IC, ICIR, portfolio returns, backtests, or trading recommendations.
