5D Smoothed Lower Breakdown

Use this Skill to compute 5日平滑下轨跌破 / 5D Smoothed Lower Breakdown from caller-provided OHLCV data.

Workflow

1. Load a pandas.DataFrame with open, high, low, close, volume; include date and symbol for cross-sectional research.
2. Call scripts/factor.py::compute_factor(df) to compute the factor column.
3. Call generate_signals(df) for a simple rank-based long/short signal.
4. Review validation_real/report.md before using the factor in a model.

Runtime Contract

• Framework-neutral Python: pandas and numpy.
• The caller owns data vendor, universe, calendar, costs, slippage, and execution modeling.
