XAUUSD CSV Data Quality Checker
Before a gold EA backtest can be trusted, the historical data must be clean. This tool checks timestamp order, missing candles, duplicate rows, OHLC validity, abnormal gaps and whether the file looks ready for MT5/Python research.

Why XAUUSD Data Quality Matters
Skipped bars change indicator values, stop timing and breakout tests.
Duplicate bars can make MT5/Python imports reject or distort calculations.
High must be above open/close and low must be below open/close.
Gold can jump, but huge gaps need session/news/context review.
Zero volume is common in some feeds but suspicious if repeated.
MT5 imports fail when dates, separators or column order are wrong.
Turn the calculation into an EA
If the tool exposed a profitable or risky condition, convert it into a coded rule with testing and guardrails.
