A bit late to the card trick party, but I got it on my second look at it
I don't know how far one can push the analogy between the illusion and the tendency for people to be fooled by the markets... for me it's not so much illusion as wishful thinking.
Like someone just said above, it pays more to build lightning fast reflexes than to drown in a pit of analysis that leaves you paralyzed. That's what I think it's important to keep entry and exit as streamlined as possible.
my 2 cents with a 1 cent stop.
