Hi, I like to use bondTransaction element from extension schema for non derivative bond trading. after check bondprice type, sounds there are only four fields available here, cleanPrice, dirty price, accruals and dirty price. so we questions are: 1) how to express yield, is there anything like fixml/FIX Yield block? 2) when trading bond, the price can be yield, discount or spread. how express it if trading rather than par. (i guess the clean price is for par) Thanks in advance. Regards, Glen
