An experimental desktop tool for replaying event streams and making market-state transitions easier to inspect visually.

Features

  • replay event data at different speeds
  • inspect bid/ask depth changes over time
  • pause on unusual spread or imbalance events
  • visualize queue movement without digging through raw text logs

Why I built it

Text logs are good for precise inspection, but they are weak for pattern recognition. I wanted a tool that made state transitions obvious enough to reason about quickly.

Technical direction

The project is helping me combine performance-sensitive C++ code with a tighter debugging interface, which is a useful combination for systems work.
