  1. The MTF knows precisely which banks to invite into an auction to trade
  2. The MTF scans IOIs and inquiries (current and historic) as well as trades then proposes potential counterparties to join an auction on the same bond
  3. The best opposite side is selected and the two members anonymously negotiate the price
  4. After the initial auction both members can agree to trade any additional quantity
  5. Other members with active/historical IOIs are then invited to trade at the executed price
  6. Names are given up after trading to perform bilateral settlement
