The most common thing that stops a new install is having nothing to backtest against. Recording
your own data takes days before it becomes useful, which is a poor first hour with a piece of
software.
So we have published one trading day of our own recordings, one post per venue, in the
Downloads board.
| Venue | Market | Symbols | Size |
|---|
| Coinbase | spot | 51 | 32.8 MB |
| Kraken | spot | 29 | 20.9 MB |
| Binance Futures | perpetual | 64 | 41.7 MB |
| Coinbase International | perpetual | 30 | 18.3 MB |
| Kraken Futures | perpetual | 32 | 18.3 MB |
All five cover the same window — 2026-08-11 20:00 to 2026-08-12 20:00 ET — at one-minute
resolution, with 68 columns per row: price, per-minute buy and sell volume, turnover, trade
strength, and ten levels of the order book on both sides.
No sign-in needed. Each post explains where to put the file, what to rename it to, and shows a
SHA-256 so you can tell a truncated download from a corrupt database.
One limitation is worth stating plainly: recordings do not carry the venue in the filename yet,
so only one venue can occupy that folder at a time. Swap the file when you want to test another.
It is on our list.
These are our own recordings from each venue's public market data feed, not a paid vendor's. One
day at one-minute resolution is a sample for evaluating the software, it is not a data product
and it is not a substitute for recording your own. Research wants more days than this, and the
one-second frame.
