Trader Alert 21-29: New feature release Monday, September 27, and UAT and DR connectivity Testing on Saturday, September 25, 2021

On Monday, September 27, 2021, MEMX is releasing a new feature where Members can opt to change the behavior when the aggregate gross and net exposure limits are breached. The default behavior of the aggregate risk controls is to reject new orders and cancel open orders. The new functionality permits Members to optionally let open orders remain, while rejecting all new orders. This functionality is currently available in MDE and will be available during the UAT this Saturday, September 25, 2021. Please contact Market Operations to enable this functionality.

Reminder: This Saturday, September, 25, 2021, MEMX is offering connectivity pre-testing for the MEMX Regulation SCI Disaster Recovery Testing in October.
