As mentioned in previous idea about COST (linked) if you think this has run too far too fast, think again. As mentioned then, the critical level is this inner resistance near 300, which if broken can open the floodgates for COST. If it closes 305 convincingly, this thing can feasibly hit 400 without much trouble. Just because a chart looks straight up in "Auto" charting mode doesn't mean it's overextended. Take another look from the right perspective and things become much clearer. Congrats if you bought then. Happy hunting and GLTA!!
