# OpenBB Feature Expansion Plan

> 67 new endpoints across 10 feature groups. All use free providers.

## Prerequisites (Do First)

### P0: Consolidate Shared Utilities
- [ ] Replace duplicate `_to_dicts` in `openbb_service.py` and `macro_service.py` with `obb_utils.to_list`
- [ ] Add `fetch_historical(symbol, days, provider)` helper to `obb_utils.py`
- [ ] Add `serialize_dates(items)` helper to `obb_utils.py`
- **Files:** `obb_utils.py`, `openbb_service.py`, `macro_service.py`, `technical_service.py`, `quantitative_service.py`
- **Complexity:** S
