Instructions for order handling for fixed income markets.

Only Best may be applied to resting and aggressing orders and:

  • Prevents submission of an order if the order’s price is not equal to or better than the best price on the book.
  • Cancels an order from the book if a new order with a better price enters the queue.
  • This order condition permits the order to be alone at the best price level or join other orders at the best price level.

Not Held (applies only to US Repo) eliminates quantity remaining from an FaKi order (tag 59=3) and ensures it will it not be included in a work-up session; however, the order can still trigger a work-up session.

AONs will have a separate book with a separate ISIN. The AON orders that cannot trade immediately can rest in the AON book. They can only trade with AON orders on the other side of the AON book that have the SAME PRICE and SAME QUANTITY.
