I'm glad to see E-Trade as part of the group putting this thing in place:
The new venue is called Members Exchange, or MEMX. Nine banks, brokerages and other firms including Morgan Stanley, Fidelity Investments and Citadel Securities will maintain control over MEMX. MEMX investors also include Bank of America Merrill Lynch and UBS, as well as retail brokers Charles Schwab, E-Trade and TD Ameritrade.
