Sites, no - I am not a big surfer of the net, I don't have the time. However, there are lots of links on www.ataa.com.au and some lists that have been published in the ATAA Journal.
There has been a rash of books on day trading published in recent years. I do not advocate day trading, because most people lose money at it. I have not read a book on it that I would recommend. Try The Educated Investor bookshop (link on my site) or Dymocks locally. You could also try US suppliers such as Traders Press (www.traderspress.com) or Traders Library (www.traderslibrary.com). They will all list books on this subject.
