Well, look what gets published tomorrow! This prevents Shitadel from selling underneath the NBBO by using crossed and locked orders. Or something. This was discussed in DD last week.

Because the proposed rule change does not: (i) significantly affect the protection of investors or the public interest; (ii) impose any significant burden on competition; and (iii) become operative prior to 30 days from the date on which it was filed, or such shorter time as the Commission may designate, if consistent with the protection of investors and the public interest, the proposed rule change has become effective pursuant to Section 19(b)(3)(A) of the Act and Rule 19b-4(f)(6)(iii) thereunder. At any time within 60 days of the filing of such proposed rule change, the Commission summarily *may temporarily suspend such rule change *if it appears to the Commission that such action is necessary or appropriate in the public interest, for the protection of investors, or otherwise in furtherance of the purposes of the Act. If the Commission takes such action, the Commission shall institute proceedings under Section 19(b)(2)(B)17 of the Act to determine whether the proposed rule change should be approved or disapproved.

** It is effective immediately. If any opposition arises they will temporarily suspend it until resolved.**
