Mandatory
This date specifies the date the original deal was agreed between party A and party B or the date of any subsequent agreed change.
Date must be a valid date expressed as YYYYMMDD (Error code(s): T50).
The trade date remains the same when a confirmation is amended (corrected/completed) unilaterally. When the terms of the deal are renegotiated on a bilateral basis, the trade date reflects the date of renegotiation in the message.
