Effective Sunday, February 21 (trade date Monday, February 22), an opt-out by Trade Type and Exchange may be requested in addition to the currently allowed Trade Type opt-out.
These options allow customers to limit their trading to only those trade type or trade type and exchange combinations that they are permissioned to use. If a trade is submitted with a trade type or trade type and exchange combination that has been selected for opt-out, the trade will not pass validation, and a validation message will be sent.
For additional information, please see Trade Type Opt Out Validations.
To initiate a trade type opt-out, please contact Enterprise Application & System Entitlements (EASE) in the U.S. at +1 312 456 1560, Europe at +44 203 379 3802 or Asia at +65 6593 5536.
