Yes, you're correct. I like reading Don's blog for his trading insight - I usually wind up thinking of a new addition to my own personal trading and coaching process after a quick visit.
I enjoy blogs that focus on a static set of financial instruments (i.e., XTrends and Don Miller............).
I believe that if you trade a single stock, ETF or Index Future for long enough time, you develop a 6th sense for its movements - thus are better able to "feel" trends.
Which is why, I personally trade the SSO the majority of the time. My traders have also benefitted immensely from taking this "get to know my cash cow" method as well. I was never one for scanning like a mad man for "in play" stocks...
Cheers!
