I like it when price recognises my predictive trend lines
, drawn when the high was put in on August 15th. Even better when it has been acting as a resistance angle. The black dashed vertical line here represents time. It's not telling me direction but suggests that's when another bout of momentum should kick in when price reaches it. The blue box is where I would expect price to reach before COST can take a breather and then think about a move up from there. As price has not dipped to the blue box yet, I'd prefer a short stock or long PUT from this level with targets at the red horizontal lines.
