About MarketParquet historical market data

We wanted reliable split-adjusted OHLCV parquet data for backtesting. Couldn't find it. Everything was either scattered across unreliable sources, unadjusted prices, or only available as CSVs. So we built MarketParquet.

Clean OHLCV data, already in Parquet, partitioned by date, ready to load into pandas or polars or DuckDB without any prep work.
