Please reply regarding the question posed below. Thank you ---------- Forwarded message --------- From: Matt <REDACTED> Date: Mon, May 27, 2024, 9:50 AM Subject: Testing order types available for comment To: <rule-comments@sec.gov> What broker(s) or exchange member(s) may I test all order types (particularly new ones) that are or will become available for comment (SEC rule making) which are released by NASDAQ, IEX, NYSE or any and all other exchanges and ATS? Recent examples being MELO and D-Limit. How may I obtain samples (historical or real time) of how those orders are interacting with the limit order book, when exactly they began to do so and how to identify them, for example which MPIDs are sending and seeing the order types and which MPIDs can use them now and which MPIDs they match with? Respectfully, Matthew Ryan McCurley
