Matchstick Replay

Replay the book. See what changed.

Bring a market depth recording (a Tardis order-book file) and Replay plays it back event by event. Pause at any moment, step through every book change, and see exactly what the book looked like when you made a decision.

It runs in your browser. Your files never leave your machine, and every session is labeled with where it came from and what you're allowed to do with it. The public demo is open to everyone; the app is invite-only while Replay is in beta.

    Formats
