Interactive Brokers TWS release notes highlighting commission-free trading with IBKR Lite and Fixes.

Commission-Free Trading with IBKR Lite

With the release of IBKR Lite, all clients will have access to streaming, real-time, non-consolidated market data for US stocks with CBOE ONE for free. TWS version 978 contains changes to support this feed.

Introducing Broker (iBroker) master users who offer commission-free trading to their clients can use TWS 978 and higher to manage client accounts and orders. Any order placed in TWS 978 and higher will route to the commission-free ZERO destination.

Additionally, TWS now includes fields for manual order route and cancel times (when applicable) for institutional users who are required to report such information under FINRA Rule 7440.

Fixes

An issue with Start and End times for orders related to a Daylight Savings time zone issue has been fixed.
