The offering is supported by introducing broker, Capital Institutional Services (CAPIS) and will allow clients to trade US equities 24 hours a day, five days a week, extending overnight trading opportunities.
The move extends existing trading capabilities beyond typical market hours, and LiquidityBook clients will be able to monitor trading activity during Blue Ocean’s overnight trading sessions, from 8pm to 4am ET, Sunday to Thursday.
“Buy-side firms have been asking for a simple, reliable way to trade overnight, and we’re thrilled to be the first order management system (OMS) to make that a reality for the institutional side of the market,” said Les Vital, principal sales specialist at LiquidityBook.
“This collaboration with Blue Ocean and CAPIS empowers our clients to act on market-moving news around the clock without needing to piece together external workarounds.”
Through its role as an introducing broker, CAPIS is also expected to further enhance the offering’s trading flexibility and efficiency, by providing access and clearing services for the trades executed through LiquidityBook.
Mark Viani, director of institutional sales and managed account solutions at CAPIS, said: “We’re excited to play a key role in enabling this expanded trading capability for LiquidityBook’s buy-side clients. As the introducing broker, CAPIS is committed to delivering seamless access and clearing services that ensure these trades flow smoothly from execution to settlement.”
