In this presentation from STAC Summit Chicago 2014, Azul CTO Gil Tene describes Zing ReadyNow! technology that allows systems to achieve optimum performance and consistency at the start of the trading day. Where common warm-up techniques may sometimes optimize for the wrong conditions, ReadyNow! technology prevents most de-optimization that otherwise would occur when "real" trades differ from the profile used for warm-up.
