I have been using Bracket Trader lately. Great little program. I also just changed computers and noticed it doesn't run very well. I had to turn off my real time virus scanner. I'll have to figure out what files are running and add them to exceptions for the scanner.
The AFL I'm working on actually combines several systems that can be turn on and off with the params window. The time of day to allow trades can also be adjusted.
I send an email alert to me handheld so I'll be able to log on and check that the stops and targets have been placed, then just let it go. It's running on the TWS simulated account right now, making play $$.
