Hello, I am pretty much just a beginner but I have some "systems" in mind and I want to test them/tweak them a little. I need a software to do this. I saw screenshots from TradeStation, so I searched for it on google but it looks like you have to sign up for a brokerage account and start trading then they will give you the software. I also happen to be 19 years old and without a lotta money. Is there any cheap software I can use that will test strategies and allow me to make my own systems? Thanks.
