# MarketPilot AI Data Quality Auditor

Run `marketpilot data-quality --csv <OHLCV.csv>`. Inspect timestamp order, duplicate bars, missing/zero volume, impossible OHLC relationships, gaps relative to the expected interval, exchange calendar, corporate-action adjustments and timezone. The built-in summary covers only a subset of these checks; manually note any unsupported checks. If there are duplicates, non-monotonic bars or unclear timezone, stop downstream calculations. A clean structural check does not prove that the provider's prices are correct or complete.
