I've been paper trading them on ToS lol. 
  
 Made like 5 K over two weeks(leveraging like 68K a trade LOL) 
  
 It's pretty easy once you get the hang of the ToS UI honestly.

You have to leverage a lot but if you can set really tight stops. You end up missing out on big ticks up sometimes because you get stopped out after 2 quick ticks down but it also saves you from having lots of money and then having to declare bankruptcy.
