How are the closing prices disseminated to the world? What is the identifier?
Amex will mark its AOCP will the “M” sale condition modifier in the UTP Trade Data Feed (UTDF). Market data vendors will receive the AOCP from UTDF and display it according to their naming conventions. For instance, the AOCP will be displayed in the Trade Recap page on Bloomberg as condition code “NC” under the exchange code “A”. Firms should contact their vendor to determine how they plan to display this information. See the last FAQ below for each major vendor’s codes.
