Note

OpenYield does not (yet) support two sided quotes. Send in two quotes to make a two-sided market. We use the Side (54) field to decide whether to use the Bid* or Offer* fields.

OpenYield acknowledges all quote messages. All quotes are Good til Cancel.

For Example, the below places a Bid Quote ID FLAME-00003 for ISIN USZ00000ZZ1X for 60 bonds at 100.12 (Offer shown too).
