SKF illustrates perfectly why it's smart to be prepared in advance for anything to happen and why you must take profits when the market offers them up. Instead of suffering the loss of $3 of your total gain on the pullback, the prepared trader puts that $3 plus $ 3 more on the short into their account and never suffers the emotional turmoil of watching your unrealized gains disappear.
Markets telegraphed what the high probability trade was in advance. Human nature told the story way before that.
