Definitely a professional site. The charts are extremely interesting but I don't have much of a feel for them. Maybe I should go to a lecture or a seminar for chart reading because reading about them in the books never gets me too far.
William O' Neill has had a few different workshops this past couple of months. I wouldn't mind attending one sometime. A bit on the pricey side (I think a full day 9-5 runs about 700.00 per person) but you could easily make it back on a couple of good trades.
