"Trader Workstation Trailing Stop Orders and Island 1/10 Cent Order Entry
You asked for it, and IB delivers. As of August 1st, you will be able to enter trailing stop orders with "Smart" order routing, and enter 1/10 cent pricing for Island using Trader Workstation. Although trailing stops have been introduced because of demand, IB does not encourage the use of trailing stop orders as they create a false sense of security, and accentuate volatility in rough markets. A new version of TWS, revised User's Guide and updated release notes will be posted just prior to implementation by August 1st."
