that uv dv narrows it down to today's a reversal breakout and we pop higher into the close or we converge the uv dv and we pull back to the mean, the drop to morning lows is not a scenario for todays picture,so lucy its 3 or 4 pics it makes it narrows down the scenarios for the day .....add in the divergence from the two spx 3 day and trans 3 day charts and it tilts towards the mean reversion
