Interactive Brokers LLC has announced a material amendment to its ATS-N filing, which outlines significant changes in how the firm manages its alternative trading system (ATS). This amendment is particularly important as it clarifies the acceptance of various order types and the reporting of transactions, impacting all subscribers to the ATS.

Founded in Connecticut, Interactive Brokers LLC operates under the SEC Act of 1934 and has a Central Index Key (CIK) of 0000922792. The firm is known for providing brokerage services and operates out of Greenwich, Connecticut. Recent filings include several ATS-N amendments, with the latest submitted on November 6, 2026.

The recent filing states, "This Material Amendment amends: (i) Part II, Item 5 and Part III, Items 7, 11 and 15 to note that the ATS accepts and price slides orders priced through either the NBBO or the limit up-limit down bands and accepts passive orders priced outside the limit up-limit down bands, but such passive orders are not included in Top of Book Data." This indicates a more flexible approach to order handling, which may enhance the trading experience for clients.

Additionally, the filing notes that trades executed in the ATS during the TRFs' operating hours are reported within ten seconds of execution, while other trades are reported within fifteen minutes of the TRFs' opening. These changes are designed to improve the efficiency and transparency of trade reporting.

Subscribers to Interactive Brokers' ATS may find these updates beneficial as they navigate their trading strategies. The clarity on order acceptance and transaction reporting could lead to more informed trading decisions and potentially enhance market liquidity.

The filing does not specify what happens next, leaving the industry to anticipate how these changes will be implemented and their broader impact on trading practices.
