SPY Trajectory over the week based on the BB Trend

As far as I can tell, there is good reason to believe those entering now will ride along the top of the boillinger band for awhile.

I suggest reducing position size at any point we exceed the band.
I see no reason currently for us to return to the bottom band.
As such, if we do go there, it will be news based. Judge the quality of news to determine issues or buying opportunities.
