Why this problem is worth solving
Market data is the most ephemeral input in trading infrastructure. Every order-book update replaces the last one. When something goes wrong at a fill — or right, and you need to understand why — the state is already gone.
A screenshot proves what a chart looked like. It cannot be stepped back through, and there is no way to verify how the numbers behind it were derived. Replay hands back the state itself — reconstructed deterministically, exact to the decimal, and identical on any machine that loads the same session.
Instead of watching each market update replace the last one, Replay lets people return to the moment that matters and inspect the state produced there.
What Replay is
Matchstick Replay is a browser-based tool for stepping through recorded market data and inspecting the order-book or candle state at any event.
Load a session, move the cursor forward or backward to any retained timestamp, and read the order-book ladder or candle state the engine reconstructs at that point. The same session and the same cursor always produce the same state.
Matchstick Replay is software for replaying recorded order-book data in your browser. It is not a trading platform and does not place orders. It is not the barter challenge of the same name, and it is not about candlestick charts.
Matthew Hendricks
Founder
Matthew was a product manager at a futures trading platform, where he worked on its market replay and tick replay. His work started with customer discovery, interviews, bug reports and QA on the older replay, then moved into product management for the new ones, driven by what users needed.
He is now building Matchstick Replay, with open input formats: a focused tool for loading recorded sessions, reconstructing market state deterministically, and moving through events to inspect exactly what happened.
Deterministic state reconstruction, fixed-point values, and open input formats make Replay sessions reproducible and auditable.
