We had the impulse up so I would think we get a little more follow through today to reach the upper BB at about 4130. We've hit a weekly structural trendline but a day or two over it is no big deal if it breaks down next week. Also in the vicinity is the 50 weekly MA at 4135, so if the rally is going to stop anytime soon, that 4130 area (more or less) seems to be a prime choice for sellers to step in.
Good luck!
