How to Use This Report

A high score does not guarantee profitable backtests. It means the file is structurally clean enough to inspect. A low score is not automatically a rejection: legacy forex exports often have zero volume and spread, which is acceptable for price-only research but not for spread-sensitive strategies.

Always check the largest gap, duplicate count, OHLC violations and weekend bars before training a model. For ML, use the ML-ready datasets; for a custom date range, use the Custom Data Builder.
