Tradestation has 2 ways to trade futures. Either through their platform, you have a very limited selection of futures contracts available. They also have the futures 4.0 platform that trades through RJ O'brien as pit traded. Options are available on the latter and a wider selection of futures.
Yes. Sometimes people need to realize that contrary to what they were taught in politically correct high school, there *are* such things as dumb questions. The overblown sense of entitlement is sometimes a sight to behold. FWIW, Tradestation only offers US futures and German futures AFAIK, and trading is only possible on US futures at present.
