Resolved - Pursuant to Rule 11.15 MEMX, on its own motion, in conjunction with other exchanges and FINRA has determined to cancel all trades today in NYSE-listed symbols that did not conduct an opening auction and both 1) occurred after 9:30:00 but before MEMX’s receipt of LULD bands; and 2) executed at a price further from the Reference Price, than the Percentage Parameters, which are defined in Appendix A to the LULD Plan. MEMX plans to process any trade breaks during the day, Wednesday, January 25. This decision cannot be appealed. MEMX will be contacting the affected parties and canceling trades on the participants’ behalf.
