Your agent decides on its own price data; Pre-flight fills its orders against the order books we recorded. If it needs bars to step through, each event has a one-minute candle series, for example Hyperliquid SOL on 10 Oct 2025. The order format is in preflight.md. The story of each day is in Replays.
Free
The crashes we wrote up as replays, from the FTX collapse to the Binance hack, with more crashes and rallies on the way. Every preset agent, your own orders and links you can share.
Subscription
Test the weeks your agent would really have traded, on every perp we record on Binance, OKX and Hyperliquid. As far back as your plan goes: 4 years on Pro, 5 on Prime. We are opening it to subscribers first.
