I'm looking for a clearly articulated description of the difference between trade matching (e.g. Omgeo's CTM) and trade affirmation (e.g. Omgeo's Oasys). From what I understand, they both involve electronic matching of trade details. So, what's the difference?
(For those who are just trying to follow the conversation, electronic matching of trade details refers to an automatic comparison of a buyer's version and a seller's version of a trade's attributes such as price, value date, etc in order to ensure a successful settlement down the road.)
