OneChronos is a U.S. equities ATS designed bottom-up to fundamentally address the growing gap between how trading venues match orders and how traders need to execute.
OneChronos is a Smart Market – the technical term for markets that match counterparties using mathematical optimization. Smart Markets have a proven ability to outperform traditional markets on metrics such as price improvement, liquidity, trade size, and fairness.
Smart Markets enable Expressive Bidding – a tool that gives market participants the fidelity of voice trading and the advantages of an electronic venue. All market participants can benefit from the unique liquidity that Expressive Bidding generates.
Smart Markets have been increasingly adopted in sectors such as manufacturing, logistics, telecom, and advertising given their demonstrated ability to:
OneChronos is pioneering the use of Nobel prize-winning (Economic Sciences, 2020) combinatorial auction techniques and artificial intelligence in financial markets, operating a Smart Market at a speed, scale and computational complexity that was not possible until now.
