estimate

object

A point-in-time snapshot of estimated values for a transfer where exact amounts cannot be locked in at quote time (e.g., when the executed rate is determined at execution time and moves with the market).

Present in both pre-execution and post-execution states:

Quoted state: top-level fields whose values cannot be guaranteed are absent; estimate holds their estimated values.
Completed state: top-level fields contain the actual executed values; estimate is retained as an immutable audit snapshot of the pre-execution estimate.
