Questions

Can I use the archive for backtesting?

That is what it is for. Each file holds prices as they stood at that scan, with nothing backfilled or smoothed, so a backtest sees only what was on the board then. It comes with prices, never picks.

Why does the archive start on June 4, 2026?

That is the first day we kept every scan. Nothing earlier exists anywhere, so we do not sell it. The archive grows by one file every day.

Is the archive free?

No. The archive is part of the subscription and needs your key. The last 7 days of the regular export stay free, and so does the sample file at /data/sample.csv: one finished NFL game, New York Jets at Chicago Bears, from every book.
