How are Account Number Justification and Masking done on Real-time Feeds?
The a/c/e trading platform allows for the entry of a twelve character account e.g. (111111111122). Clearing only recognizes a ten character account, therefore positions 109 through 118 of the TREX record will be populated with the first 10 characters e.g. (1111111111). Customer account numbers will NOT be masked or right or left justified before they are sent to firms in the real time feeds.
