CORE FIX Included in LULD Repricing
If you enter limit-priced orders using CORE FIX or OUCH order entry protocols, those orders will be repriced on entry under the Exchange's Limit Up‑Limit Down rules the same way as OUCH orders, per proposed Equity 4, Rule 3100(b)(1)(A)(i)e.2.a). This update is part of the Rule 3100 changes and is planned for implementation on August 10, 2026.
Rule 3100 Becomes Operative Immediately
The amended Rule 3100 framework (including the CORE FIX update) was made operative upon filing after the SEC waived the usual 30‑day delay, and the Exchange proposes to implement it on August 10, 2026. This allows the Exchange to bring the approved Rule 3100 into operation in its current form.
