Mandatory in a conditional sequence (C2)
This field specifies the date the block trade was agreed between the fund manager and the executing broker.
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 renegociated on a bilateral basis, the trade date reflects the date of renegociation in the amend message.
