# Alt Data Directory This folder holds supporting datasets that are separate from the core market-data pipeline. - `options/` contains raw and processed options datasets. - `institutional/` contains institutional flow and positioning datasets. - `external/` contains macro, index, FX, and other outside-market reference data. - `metadata/` contains research notes and supporting documentation for alternate datasets. Keep the same `raw/` and `processed/` split inside each alternate-data area where possible.
