The newcomers to this thread need to understand one thing about (master)luc(if):
The guy is, as far as we can tell, a pretty competent trader, but he made wrong calls as well in the past. Which means he's not infallible, and/or he sometimes has a different goal in mind when he posts, i.e. he withholds something he knows or believes on purpose.

Shock! Gasp! Someone on the Internet might have an ulterior motive! Why I never would have imagined that!
