As previously announced in the May 18, 2022 Alert, MIAX Pearl Equities Exchange will introduce new functionality to accept additional order instruction combinations prior to the Exchange’s opening process being complete and trading during a halt.  MIAX Pearl Equities will accept orders with a Post Only instruction and a time-in-force of Regular Hours Only (RHO), and orders with a Minimum Execution Quantity (MEQ) instruction and a time-in-force of RHO beginning at 7:30 a.m. Eastern Time.  The Exchange will also begin to accept and retain these order instruction combinations during a trading halt.  These orders will queue and be submitted in time priority to the Exchange’s order book when the opening or re-opening process is complete.
