Alternative Trading System (ATS)
OneChronos operates a U.S. equities Alternative Trading System (ATS) designed to bridge the gap between traditional trading venues and modern trading needs. Utilizing a Smart Market approach, the platform employs mathematical optimization for order matching, which aims to enhance price improvement, liquidity, and fairness. The ATS supports NMS securities, including single stocks, ETFs, and ADRs, and conducts periodic auctions approximately every 100 milliseconds.
Technology and Matching Engine
The OneChronos matching engine is located at Equinix NY5 and does not route orders externally. It constructs a view of the National Best Bid and Offer (NBBO) using data from SIP (NYSE CTA feeds & Nasdaq UTP) and supports a variety of order types, including Limit Orders, Peg Orders, and Expressive Orders. The platform enables Expressive Bidding, allowing participants to specify detailed execution instructions that enhance trading algorithms.
