Seeing is believing - I don't know why this works this way except that everyone uses pivot points and so it makes sense to buy and sell in a channel such as this.
We've got a little BOB along with some tweezer bottom action and Brett Steenbarger's Bull Bar at 13:15. But it can't break the pivot point barrier.
If someone told you that the Q's were stuck in a 14 cent range today would you have believed him? I doubt it.
