Can I practice day trading

Hi guys, I am trying to figure out the best way to get my feet wet in day trading stocks. I have tried paper trading many times but I dont think that gives me a good idea of how to read the flow of orders. I found a few websites but do you know of any others? I tried ninja and I have a problem because it says I need a data vendor. Is there an easier way to use? Tradingsim looks nice because I dont have to do that but I dont get to see my trading performance. maybe they will fix that? The third one, it seems like I need a data provider as well?

would you guys give me a hand?

1) www.ninjatrader.com
2) www.tradingsim.com
3) www.tradingsimulatorsoftware.com

Thanks for the response. Those two you recommended to me are forex brokers. I would like to practice equity trading.

I have searched all day long...I think tradingsim.com probably is my best bet for now, especially because I am at work and cannot install anything on my computer.

Let me know if you guys come accross any others.

Thanks
