OneChronos

OneChronos operates an equity trading technology that uses a Smart Market approach to match orders. It supports expressive bidding and combinatorial auction techniques to improve price, liquidity, and fairness in U.S. equities, with integration into existing algorithmic workflows.

OneChronos offers an automated U.S. equities alternative trading system (ATS) that matches orders using mathematical optimization and combinatorial auction techniques. It enables Expressive Bidding, provides point-in-time auctions roughly every 100ms, and matches within or at the NBBO with a single clearing price per symbol. The platform supports standard FIX 4.2 order flow, customization of execution objectives through constraints, non-displayed trading with no data feeds, and multi-objective execution aligned with VWAP, IS, liquidity seeking, and more. It can facilitate single-security and multi-security strategies, ETF synthesis, pairs trading, and portfolio hedging, and is designed to fit into existing routing workflows.

Who it’s for: Institutional traders and brokers seeking enhanced execution and liquidity through a combinatorial auction-based, non-displayed, fast-matching ATS for US and international equities.
