1. mostly they sell em often there is a free trial for a month even though they charge like $500
2. It depends a lot on what kind of a tool you need. If you need one that uses prior data to back-test you will probably have to pay a steep price. If a "position analysis" tool that will predict the future results under specified circumstances, you can get "The Options Toolbox" for free at http://www.cboe.com/LearnCenter/Software.aspx
