The likelyhood of becoming sucessful at day trading is far less than swing or position trading (which itself has around 90% mortality in the 1st year, probably much like poker).

There's too much pressure to be on your A1+ game every day, and many successful longer term traders have been quoted as saying that having a real-time quote screen on their desk is akin to having a one-armed bandit sitting there.

Day-trading appeals to gamblers and action junkies and actively encourages their vice through the perpetually flashing red and green quotes sending them into a trance.

The commission and slippage costs for day-trading would also be extremely difficult to overcome, and so you'd be limited to trading markets that move in a sufficiently wide daily channel.

Having said this, that graph (if true) is the dog's bollox.
