Propr Open-Sources A/B Booking Algorithm
Summary
Propr announces it has open-sourced its hybrid A/B booking algorithm and explains A-book vs B-book routing through Hyperliquid. The post links the ab-booking repository, details replicated order book matching for B-booked traders, and previews open sourcing of the paper trading engine plus UI indicators showing A or B treatment. This improves transparency and trust in the community.
Great to see new faces in the community.
A few of you asked about our booking model. We run a hybrid A/B system. In the spirit of transparency, we've just open-sourced our A/B booking algorithm: https://github.com/XBorgLabs/ab-booking. It will evolve as our model matures.
A-booked traders are routed through Hyperliquid's order book directly. B-booked traders are routed through a replicated Hyperliquid order book where we match depth 1:1, more details here: https://discord.com/channels/1111607533883367535/1446593350097436732/1478716826786725909. We will also look to open source the core of our paper trading engine.
The user interface will show whether the system treats your orders as A or B booked. A longer post is coming on our commitment to transparency
