Hi Bobby,
thank you for your post. I used Bracket Trader for a little while but would recommend that you look into Button Trader should you want real performance. Unfortunately, I don't hold shares of that company so this is free advice, lol. They offer you a 6 months free trial simulation mode with full features (provided you have an IB account which you have). Just look at it and I am convinced you'll be amazed of that powerful trading engine. Especially when trading commodities this is a valuable tool.
Best of all trades,
Peter
