Improved
"OptionDeliverable.amount" documented as non-nullable for delayed settlement
October 7th, 2026
Clarifies the amount field on the OptionDeliverable schema. The field is a non-nullable string: when deliverable settlement is delayed and the amount is not yet determined, the API returns "0" with delayed_settlement set to true (previously documented as nullable). Response behavior is unchanged.
