You can "paper trade" by simply keeping a written diary of how you would have placed your orders. You can get 20 minute delayed stock quotes at fidelity.com (with no account), or several other sites. It's good enough to practice with. Just record your actions. The more details you WRITE down, the better.
If you don't have the discipline to keep a good written record of your "paper trades," then I think you are unwise to venture into real money trading. Most good books on the stock market emphasize daily discipline in keeping written records (spread sheet and diary etc). If you can do this daily, over several months ... that is great rehearsal for the real thing. Just my humble opinion, as I am also relatively new to this game. I wish you all the best.
