Hi, We are going to support RFQ and Order Placement (without any prior quote) in our new system. What FpML version should we use and what are the corresponding messages to support these 2 flows? After going through the documents, we find that: 1. In 4.9, RFQ is supported but there is no message to support order placement 2. In 5.3, pre-trade messages are not approved yet. So what is your advise for this? Thanks, William
