I don't personally agree with the "slow" as most trading applications are giant java behemoths with custom UI kits anyways. As long as you can have 8-12 charts

I don't personally agree with the "slow" as most trading applications are giant java behemoths with custom UI kits anyways. As long as you can have 8-12 charts all updating 30 times a second or what ever update frequency you have and not crash a standard laptop the performance is fine. I do agree with the other part, there is nothing making your application "special". There is no special feature.
