Close-Order Timing May Lower Trading Fees
The NYSE changed how it defines “last modified” for D Orders that execute in the close, effective December 5, 2025. The new definition removes order cancellations and the prior broker-badge/firm/symbol/side restriction and defines “last modified” as the later of entry time or the final modification; this can move orders out of the Late D Order bucket (last 1 minute before close) into Mid (10 minutes up to 1 minute) or Early (earlier than 10 minutes) buckets and may result in lower fees for member firms that enter or modify D Orders earlier. The fee differentiation applies after the first 10,500,000 ADV of aggregate executions at the close by a member organization.
