The Investors Exchange LLC (IEX) is proposing to change one of its rules, specifically IEX Rule 11.190. They want to stop using one of their two mathematical calculations, called CQI 1, which helps them predict changes in Protected Quotations. They have found that the other calculation, CQI 2, works better and is used more often, making the first one unnecessary. The Securities and Exchange Commission is inviting public comments on this proposed change until April 4, 2025.
