that's kind of the point, the monthly bb has "capped" each advance since 03...so for 2 years we've been in a trading range. We've just broken out above that trading range the past couple months, after a middle bb tag on the monthly in oct. So why can't we break up now, and get that upper bb moving up? Because you think the 4 year cycle won't allow it?
As others have pointed out, there's little resistance between 2300 something and 2800+, I have ~2406 as the point we really explode. If we don't turn around now and pop quickly back over 2300 and towards 2400 within the next few weeks, then your scenario of staying in the trading range I'm afraid may be right.
