PriorStates HFT trading system demo
Table of Contents
This page is a capture in the inbox bucket of the product backlog — a pre-sprint idea, not yet pulled into a sprint as a story.
1. What
A public, browser-based demo of a C++ low-latency (HFT) trading system, at https://priorstates.com/demo/?tab=demo. Its author has extended it to cover CME, BrokerTec and Tradeweb. Besides live trading processes, the site shows reference data and a linear-model research process. It also supports other ML models: XGBoost, scikit-learn fitted models and PyTorch fitted models.
2. Why
A working reference for how a trading system presents itself on the web: live processes, reference data and model research on one site. Look at it when designing ORE Studio's ores.web trading and research screens, and when deciding how model research (linear and ML) fits next to pricing and risk.
