for a free mag it is packed with info; 25 rules by Doug Zalesky, candle charting by Steve Nison, SP clues for day trader by Kevin Pendley, Linda R, John Bollinger, Adrienne Toghraie...and much more.
Yes, it is a very cool resource and it is free (just register with an email). There is even a nifty article re ETF trading from Deron (didn't he have a thread on ET a while back?). What did you find the most interesting, nkhoi?
hard to say because each article deal with diff subject, strategy, psychology etc., but with this kind of ranging market I think Deron has the right idea in exploring diff type of trading vehicles.
