One page per instrument for the tickers people backtest most: what the archive holds for it,
first and latest bar, a live sample of its newest 5-minute session, corporate actions applied,
and the Python snippet that pulls it out of the per-day Parquet files.
Every one of these symbols ships inside the same files; the archive covers 16,000+ stocks (8,500 delisted),
5,000+ ETFs and ~130 futures contracts -- 21,000+ symbols in total, current through 2026-10-30.
These pages are a curated set. Every symbol in the archive is in the same daily files: open any daily file and filter on the ticker, or search the newest file with the and change the symbol.
