data-vendor-cross-validation-for-backtests skillA

data-vendor-cross-validation-for-backtests is agent-read markdown (skill) from himanshuj16/algo-trading-skills: Use before trusting a single vendor's history, to cross-check OHLCV bars against a genuinely independent second source for price discrepancies, phantom volume, stale prints and missing-bar coverage..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
