Yes, there was a follow up study released showing that day trading in stocks had FAR better results, but I can't find an English link to provide the data. 
  
 But basically the ones trading paper stocks had a consistent 40% of the sample making money, while futures traders were taking up the ass everyday.

Frankly future really aren't designed for trading.  There are two reasons to fuck with futures: hedging risk in some way or arbitrage.  There is just no room for day traders there. 
  
 Personally, I'm not sure day trading stocks is a great idea either unless you're already rich enough it doesn't matter what you do.
