Day 1

A quick update on our first day of trading.  We executed our first trade at 7:48:43 AM, 100 shares of ED at $73.90.  Over the course of the day, MEMX traded 60,957 shares on 857 executions and had 25 firms execute trades.  All in all, it was a successful first day and another important step in our journey to transform the exchange landscape. 

We greatly appreciate all the engagement from our members.  While we are only trading seven symbols, the reason we go through a phased rollout like this is so we can identify how the system performs in a variety of conditions and with gradually increased activity. Today was incredibly helpful in those efforts. Getting through our first settlement cycle will be an important next step.  We look forward to expanding our symbol universe. But, first and foremost, we are committed to minimizing any potential market disruption. 

We also took the time today to honor an amazing woman and her contributions to our country. At 2:27PM we observed a moment of silence in recognition of Ruth Bader Ginsburg – serving twenty-seven years as the second woman appointed to the Supreme Court.   

We start again tomorrow with pre-market trading at 7AM EST in advance of our normal trading session at 9:30AM EST.  

We will keep you updated on our progress, thank you for your support!
