Qu'est-ce que « Trade confirmation, affirmation » ?

A trade confirmation is the executing party’s statement of a trade’s terms — security, side, quantity, price, trade and settlement dates, accounts — sent to its counterparty. Affirmation is the counterparty’s (for an institutional trade, the investment manager’s or its custodian’s) agreement that the confirmation is right, after which the trade can be settled without further intervention.
