On December 17, 2024, the New York Stock Exchange LLC and several related exchanges proposed a rule to the Securities and Exchange Commission to change their connectivity fee schedules. This involved adding fees for connections from the Mahwah Data Center to trading floors. However, by December 31, 2024, the exchanges decided to withdraw these proposed changes. The proposed changes had been briefly open for public comment as part of the regulatory review process.
Simple Explanation
The New York Stock Exchange and some related exchanges wanted to change how much they charge for certain connections, but they decided not to make these changes right before the new year. They didn't say why they changed their mind, but it was something they thought about for a little bit.
