How are we different?

MEMX offers a simpler platform and features that will benefit both retail and institutional investors, including:

  • • A limited number of order types to promote simple and transparent interactions
  • • Investments in the best and latest technology to deliver fast and efficient execution
  • • Lower pricing on market data, connectivity, and transaction fees

As the only member-owned equities trading platform, MEMX will represent the interests of its members and their collective client base, comprised of retail and institutional investors, on U.S. market structure issues.

Why now?

Competition in the marketplace brings out the best in all the participants and benefits investors. Increasing the diversity of exchanges improves overall market robustness, stability and innovation, which will ultimately result in improved operational transparency and reduced fixed costs.

  • • The largest U.S. online retail broker-dealers, which serve retail investors placing millions of orders each day
