Price improvement of $1bn+ in midpoint executions over 10 years

  • Global dark ATS/MTF, operating in 36 countries
  • Technology rejects trades that don’t meet our standards; for example, Liquidity Guard filters out 1 million shares a day in the U.S.
  • Rewards size over speed, using a size-based pro rata matching logic instead of the price-time method many other pools use
  • Minimized information leakage: We do not communicate IOIs or route orders outside POSIT
  • Access to unique institutional block liquidity, readily accessible at the BBO midpoint

ITG is at the forefront of the industry in our commitment to providing transparency. We have published  POSIT Frequently Asked Questions as well as POSIT’s Form ATS.
