I tried the stripped down version of Trend and it's a "no go" for me. The interface is beautiful, but everything they stripped out is something I wanted to use.
Tradehawk is really good. They recently had an update that seems to have helped with some of the issues I was having. This software is how most other brokers software looks and feels. But, it's very limited in what it can do, so don't expect all the tools you get from IB or TOS.
