Stricter Limit Order Price Protections
24X changed the limit order price protection percentages used in the Pre-Market, Post-Market, and 24X Market Sessions to match the Core Market Session. The old percentages were 20% for securities $0.00–$25.00, 10% for $25.01–$50.00, and 6% for >$50.00; the new percentages are 10% for $0.00–$25.00, 5% for $25.01–$50.00, and 3% for >$50.00. The rule became operative upon filing on November 28, 2025, and is intended to reject limit orders priced far from the National Best Bid or Offer to provide greater protection to market participants trading on 24X.

2026-17183, Regulation Crypto Assets
The Securities and Exchange Commission ("Commission") is proposing new rules to create a tailored offering regime for certain investment contracts involving crypto assets. The proposed offering regime is intended to facilitate capital formation and accommodate innovation within the crypto asset markets while, at the same time, ensuring that investors are adequately protected and provided with the information they need to make informed investment decisions. The proposed rules would be set forth in a new regulation titled "Regulation Crypto Assets" and would include two exemptions from the registration requirements of section 5 of the Securities Act of 1933. The first exemption would permit offerings of up to $5 million during a four-year period. The second exemption would permit offerings of up to $75 million during each 12-month period. Under both exemptions, issuers would be required to make certain principles-based narrative disclosures available to their investors. In addition, issuers under the second exemption would be required to provide financial statements and would be subject to ongoing reporting requirements. Issuers that rely on these exemptions would remain subject to the antifraud and antimanipulation provisions of the Federal securities laws. The proposed rules also would include a conditional safe harbor from the term "investment contract" in the definitions of "security" in the Securities Act of 1933 and the Securities Exchange Act of 1934. If the conditions of that proposed safe harbor are satisfied, then a crypto asset would be deemed not to be subject to an investment contract for purposes of those definitions of "security."
