The Miami International Securities Exchange, LLC has submitted a proposal to the Securities and Exchange Commission to increase the number of Limited Service MIAX Express Interface Ports available to market makers without changing existing fees. This expansion is needed due to higher customer demand and market volatility, which have increased network traffic. Even though this expansion will come at a cost, the Exchange aims to offer more ports to ensure sufficient and equal access to its systems for all market participants, while maintaining fair competition and efficient port usage. They emphasize that the decision to purchase additional ports is voluntary for market makers.
Simple Explanation
The Miami Stock Exchange is giving market helpers more online tools to use because more people are trading and the system is busier, but the helpers have the choice to use them or not.
