An ultra-fast order matching engine core for exchanges written in Java, built on LMAX Disruptor, Agrona, Eclipse Collections, and OpenHFT. It includes order matching, risk control and accounting, disk journaling/snapshots, and trading/admin APIs with sub-millisecond latency at millions of operations per second.
Use cases
- build a cryptocurrency exchange matching engine
- run a low-latency order book for stock trading
- process millions of orders per second with microsecond latency
- implement risk control and accounting for a trading platform
- create a forex or crypto exchange backend
- benchmark lock-free order matching performance
When to choose
- you need extremely low-latency, high-throughput order matching on the JVM
- you are building a crypto, forex, or stock exchange core
- you want lock-free, disruptor-based architecture with journaling and snapshots
When to avoid
- you need a full turnkey exchange with UI, wallets, and compliance out of the box
- your team is not comfortable with low-level Java performance tuning
- you need active commercial support or frequent updates
